2.8 Description

New demands for managing distribution systems call for control devices inherently reliable and



intelligent. Customers require a built-in capability for data gathering and communication, along with an

extremely low maintenance product.

The Jinkwang electronically controlled, three phase automatic recloser (hereinafter referred to as “the

recloser”) provides reliable and economical over-current protection for distribution circuit, ranging from

15 through 38kV.

The recloser senses line current and automatically interrupts the phase of the distribution circuit to

which it is connected when line current exceeds the minimum trip level. Next, it automatically recloses to

restore ser-vice and monitors the line to determine if the fault has been cleared. If the fault is

permanent, the recloser sequences to lockout after one, two, three, or four preset trip operations

Once the recloser sequences to lockout, the recloser must be manually reset to restore service.

Should the fault clear before lockout, the recloser will reset automatically for another sequence of

operations. The recloser can also be set for non-reclosing operation (lock out after the first trip

operation) The recloser can be remotely set for non-reclosing operation via the remote non-reclosing

feature. The trip operations of the recloser can be all fast, all delayed, or any combination of fast

operations and delayed operations up to a maximum total of four. Fast operations clear temporary faults

before branch line fuses are weakened. Delayed operations allow time for fuses or other downline

protective devices to clear to limit permanent faults to the smallest section of line.

The Jinkwang type JK-REC recloser has a characteristic as followings.

1) The recloser meets actively in distribution line protection coordination that change variously by

control technology that use microprocessor, and are being operated locally or remotely.

2) Communication protocols to DAS make the automated protection coordination possible.

3) The control has a total of 48 built-in T-C curves, and a T-C curve, which has a time multiplier and a

minimum response time applied to the fundamental curve and a high current lockout characteristic,

allows programming via keypad or RS232 communication port on the front of control panel.

4) Fault recording for analysis can be backed up using LCD display or handheld controller applying

gradually fault recording that need in the maintenance on the distribution lines.

5) All operating parameters and settings are easily programmable via handheld controller or PC using

RS-232 port on the front panel.

6) The control is equipped with the function of sequence coordination to prevent unnecessary operation

of the upstream reclosers when two or more reclosers are being operated in series.

4. CONSTRUCTION

The recloser shall consist of a mechanism housing including magnetic actuator and vacuum interrupter,

and controller. The vacuum interrupter provides greatly enhanced long contact life.

The vacuum interrupters are installed into tank that is made of stainless steel. The lightweight and

portable gas insulation effectively reduces installation costs.

4.1 Tank

The tank of the recloser is fabricated from cold rolled steel and plate. The material used is 304L stainless

steel (SF6 Gas insulated type only)and the design thickness is a minimum 3㎜.

4.2 Switching module

In contrast to the majority of conventional circuit breakers, this patented design incorporates three

independent magnetic actuators: one per pole. This minimizes the number of moving parts, all of

which are symmetrical about the central synchronization of the poles operation.

The vacuum interrupter and the magnetic actuator are located at opposite ends of a hollow support

insulator. The actuator armature is rigidly coupled to the vacuum interrupter moving contact by a linear

drive insulator within the support insulator. This provides direct linear movement in both directions and

avoids the use of rotating shafts, bearings and bell cranks.

The result is a maintenance free switch module with a long trouble free mechanical life.

The actuators are situated inside the frame. A synchronizing shaft connects the three poles and

performs three functions:

▪- synchronization of the poles operation

▪- control of the auxiliary switches

▪- link-motion drive of mechanical interlocks.

4.2.1 Magnetic actuator

The actuator is held in its two end positions without the use of mechanical latches. in the OPEN position

the armature is held by the opening spring. in the CLOSED position the armature is held by magnetic

flux produced by a ring permanent magnet.

This actuator has only one coil. To close and trip the actuator it is necessary to inject current into the

coil in different directions.

4.2.2 Vacuum interrupters

As soon as the vacuum interrupter contacts open, the interrupting current initiates a so-called

“vacuum arc” that burns essentially in plasma originating from evaporated contact material.

The current continues to flow through this plasma until a current zero. At this moment the arc is

extinguished and transient recovery voltage appears across the open gap.

If the contact surface is locally overheated it produces a lot of vapor, resulting in the deterioration of

the vacuum followed by electrical breakdown. To avoid this, effective control of the vacuum arc is

necessary.

The most effective way to achieve this goal is to apply an axial magnetic field produced by the

interrupting current itself. This method is implemented in vacuum interrupters developed.

Several major benefits result from this design:

▪ High interrupting capacity

▪ Very compact dimensions

▪ Low chopping current (45 amps) This limits inductive switching overvoltage to safe values.

▪ Axial magnetic field minimizes contact erosion and ensures a very long and reliable life.

4.2.3 Operation of switching modules

Closing

In the OPEN position the vacuum interrupter contacts are held open by the force of the

opening spring in the actuator acting through the drive insulator.

To close the vacuum interrupter contacts a current pulse, derived from the closing capacitor in

the control module, is injected into the actuator coil.

▪ The current in the coil produces a magnetic flux in the gap between the upper yoke and the

actuator armature.

▪ Rising coil current increases the magnetic flux and the electromagnetic attraction between yoke

and armature increases to overcome the restraining force of the opening spring. (Line1)



▪ The armature, drive insulator and moving contact start to move.

▪ As the armature moves towards the upper yoke the magnetic air gap decreases and consequently

the magnetic attraction force increases. This increasing force accelerates the armature, drive

insulator and moving contact to a closing speed of 1 m/s. This optimum speed ensures a complete

absence of contact bounce and reduces the probability of pre-strikes of the vacuum gap before the

contacts close. (Line 2)

▪The accelerating armature also generates a back emf in the coil and reduces the coil current (Line 1-

2)

At contact close (Line 2) the moving contact stops but the armature travel continues for 2mm

under rapid deceleration caused by compressing the contact pressure spring.

▪ At the limit of its travel the armature latches magnetically to the upper yoke. (Line 2a) The moving

armature induced back emf collapses and the coil current again increases (Line 2a-3)

saturating the ring magnet.

This saturation increases the power of the ring permanent magnet to a level that generates flux

to hold the armature in the CLOSED position after the coil current has been cut off by an

auxiliary switch. ( Line 3) Testing has proved that this flux is sufficient to hold the actuator

CLOSED even under vibration and impact conditions.

▪The travel of the armature also compresses the opening spring in preparation for the next opening

operation.

▪The synchronizing shaft is also driven through 44°of rotation during the closing operation and

provides position indication, auxiliary switch operation and mechanical interlocking actions.

Opening

▪To open the interrupter a current of opposite polarity, derived from the opening capacitor in the

control module, is passed through the coil for 1520 milliseconds. (Line 4-5)

▪This current partially demagnetizes the ring magnet and reduces the magnetic holding force on

the armature.

Opposing forces from the charged opening spring and the contact pressure spring cause the

armature to release and accelerate rapidly. After 2 mm of free travel it engages with the drive

insulator and thus the moving contact.



▪The peak force produced by the armature at this point exceeds 2000 N which ensures easy

breaking of any micro-welds at the contact surfaces which can appear due to short circuit

current action.

▪The moving contact accelerates rapidly ensuring a high interrupting capacity. (Line 5)

▪At full travel (Line 6) the armature, drive insulator, moving contact assembly is again held open by

the opening spring force.

▪The synchronizing shaft is also driven through 44° of rotation during the opening operation and

provides position indication, auxiliary switch operation and mechanical interlocking actions.

Manual closing

Closing can only be carried out through the control module.

Manual opening

The module may be manually opened.

By rotating the synchronizing shaft a force exceeding the magnetic attraction forces of the ring magnet

is applied to the armature, which then starts to move.

As the air-gap increases the opening spring and contact pressure spring over come any magnetic

holding force and the interrupter opens.

Auxiliary switches

All switching modules are equipped with thirteen auxiliary switches, six normally open (NO) and seven

normally closed (NC). Auxiliary switches are operated by cam that is fitted on the synchronizing shaft.

One NC auxiliary switch is used for interconnection with the control module. All others are available

for external use.

in service.



6. RECLOER OPERATION

Warning

Do not reply on the open position of the open/lock handle(yellow color) or the contact position

indicator; it does not ensure that the line has been de-energized. Always establish a visible disconnect.

Failure to follow proper safety practices can result in contact with high voltage, which will cause severe

personal injury.

Caution

Pushing the yellow manual operating and Lock handle to the closed position will not close the recloser.

All close operations are initiated by the FTU-R200 microprocessor-based recloser control.

6.1 Closing Operation

Closing operation should be performed with a close button on the control panel necessarily. But, before

operating the recloser on the control panel, make sure a position of manual open& lock handle. Check

whether the manual open&lock handle indicate lock position or not.

Note: When the recloser is closed, the manual operating and Lock handle should be positioned in free

condition(upward).

6.2 Opening Operation

The manual operating and Lock handle(yellow color) in the recloser is used to open and lock out the

recloser. If the recloser is opened with a manual operating & lock handle, it automatically operates to

lockout. So, it disable in the electrical and supervisory closing.

The manual operating and Lock handle is designed to be operated with a hot stick. Pulling down the

manual operating and Lock handle open the main contacts of the recloser. Contact position is indicated

by the open flag of the contact open indicator. The handle will remain down in the open position and

not return upward in the close position.

Therefore, when the recloser is closed, the manual operating and Lock handle should be positioned in

free condition.

Note: When the recloser electrically operates to lockout, the open/ lock operating handle will not drop

by the open position. The handle remains in the open position only after manual operations are

performed.



6.3 Lock Operation

When the manual operating and Lock handle has been manually pulled down into the lock position, any

current over the minimum trip rating will cause the control to automatically lock the recloser. The

manual operating and Lock handle does not interfere with manual recloser operation or operation via a

SCADA trip or close signal. The recloser can be opened or closed manually regardless of the position of

the lock handle.



7. MAINTENANCE

Warning

Always use a hotstick when working with the recloser. Failure to do so could result in contact with high

voltage, which will cause severe personal injury.

Caution

The equipment requires routine inspection and maintenance to ensure proper operation. If it is not

maintained it may fail to operate properly. Improper operation may cause equipment damage and

possible personal injury.

7.1 GeneralJin Kwang’s reclosers require inspection and maintenance to ensure proper operation.

If the recloser is not adequately maintained, it may fail to operate properly. Even though the recloser has

been designed as a low maintenance unit, maintenance interval depends on the local climatic condition.

Jin Kwang recommends that the recloser be inspected and maintained for long life.

7.2 Frequency of maintenanceTo assure proper and trouble-free operation, reclosers must be

maintained when they have operated the equivalent of a rated duty cycle.

Note: ANSI C 37.61, “Guide fot the application, Operation and Maintenance of Automatic Circuit

reclosers”, gives a procedure for converting the rated standard duty cycle into an equivalent duty

cycle based on the actual operating duty of the recloser

7.3 Check the operation of low pressure indicatorThe recloser is filled with 0.5kgf/cm2 of SF6 gas in

normal service, however, if gas pressure drops to 0.1 ~ 0.2kgf/cm2 or less by means of any cause, a

low pressure locking device works to prevent the operation of the switch manually and electrically (from

local control panel and from remote location).

At the same time, a low gas pressure indicator located at the side of switch will be shown and a low

pressure indicator lamp on the control panel will illuminate to indicate that switch operation has been

blocked.

7.4 Check the recloser visuallyInspect each of the bushing for breaks, cracks, burn or heavy pollution

and other part of the recloser.

1) If polluted, clean the bushing.

2) If damaged, replace whole of the recloser with new one.



FTU-R200 CONTROL UNIT

8. OVERVIEW

8.1 PROTECTION OF DISTRIBUTION LINE

Distribution lines have their own equipment outdoors, the types of loads are various, and the

configurations of the networks are flexible and complicated. There are many kinds of fault causes such

as direct contact of trees or birds, natural phenomenon of lightning or heavy snow, and fault spread-out

due to customer’s facilities. Among these faults, most of faults are temporary and the dominant fault

type is ground-fault.

For rapid fault detection and fault section isolation, blackout area minimization, many protection devices

such as Recloser, Sectionalizer, and Line Fuse are adopted. Among these devices, Automatic Circuit

Recloser is the most important protection device, whose main functions are fault current trip and auto-

reclosing.

One distribution line has over 2 Reclosers of serial connections or Recloser – Sectionalizer - Line Fuse of

serial connections. This configuration is the concept of Primary Protection and Back-up Protection. In

other words, protection coordination is required in the way that a protection device nearer to fault point

operates first to eliminate the fault and other devices farther from fault point are configured to operate

later with time delays.

8.2 FUNCTION OF AUTOMATIC CIRCUIT RECLOSER

When a fault occurs on the load side of Recloser installed location, Recloser detects fault current, trips

fault current at high speed, and does reclosing actions after the set time to re-activate the faulted

section. In case of temporary fault, the fault can be removed by itself according to high-speed trip and

dead time before reclosing actions. But, in case of

permanent fault, because fault current is still detected after trip and reclosing actions of pre-set counts,

Recloser is locked out finally as opened.

Recloser has the time delay element in protection function of its controller and can be freely configured

for protection coordination with other protection devices.



8.3 MAIN FEATURES OF FTU - R200

Recloser body is connected serially to distribution line to operate open / close of the line, and Recloser

9.5.2.2 IEC60870-5-101

IEC 60870-5-101 is primarily used with relatively slow transmission media on the asynchronous V.24

interface. The standard promises baud rates of up to 9600 bit/s, with much higher baud rates (<115200

bit/s) actually being used. X.24/X.27 interfaces with baud rates up to 64000 bit/s, also part of the

standard's description, could not establish themselves and are rarely used.



9.5.2.3 IEC60870-5-104

IEC 60870-5-104 (also known as IEC 870-5-104) is an international standard, released in 2000 by the IEC

(International Electrotechnical Commission). As can be seen from the standard's full designation

'Network access for IEC 60870-5-101 using standard transport profiles', its application layer is based on

IEC 60870-5-101. IEC 60870-5-104 enables communication between control station and substation via a

standard TCP/IP network. The TCP protocol is used for connection-oriented secure data transmission.

9.6 RECORDING

9.6.1 EVENT RECORDER

9.6.2 WAVEFORM EVENT RECORDER

Fault & PQM waveforms recording function are used to store the measured instantaneous

current/voltage values of pre-fault and post-fault at 128 samples per cycle. Record length, trigger source

and trigger position of pre/post-fault in recorded data are adjustable. The record types are 128 samples

* 20 cycles, 64 samples * 40 cycles, 32 samples * 80 cycles, 16 samples * 160 cycles.



According to the purpose, operators can set the fault recording trigger source and trigger position of

pre-fault/post-fault. Trigger position means the percentage position in recorded fault data, and the pre-

fault data are recorded before this point and rest of the data are recorded as the post-fault after this

point. The recorded fault waveforms are also uploaded to FTU PC S/W, and current/voltage waveforms

at fault and protection elements operation can be analyzed with fault evaluation.

This waveform recording fuction follows the COMTRADE file format rule.

13. PROTECTION FUNCTIONS

13.1 FAULT DETECTION

FTU detects the Phase & Earth Fault and trip the breaker.

The fastest operation time is within 45msec including auto-recloser operating time. There are 58 trip

curves, which can be selected for fast and delayed operation respectively. The Curve can be edited by

using several parameters, i.e. time multiplier, time adder and minimum response time.

And high current trip element can be used for instantaneous trip. It is definite time characteristics.

During cold-load condition, pickup multiplied by cold-load multiplier. During the cold-load condition,

time-delayed curve is applied instead of fast curve. This function can be enabled or disabled by cold-

load multiplier.

Earth fault detection function can be enabled or disabled by ‘Ground Protection Enable’.

operation is required, for example, when closing onto a fault.

In Single Shot Operation the controller goes directly to lockout after one trip and will not auto-reclosing.


Single Shot Time 0~180 10 1 sec

13.1.4 TC CURVE

FTU-R200 has 54 types of built-in TC curves including ANSI, IEC Standard curves. And customer can

define additional 4 curves as his own curves by using PC Software. Basically, built-in curves have inverse

time characteristrics, but can be easily adjusted by three parameters such as multiplier, time adder and

minimum response time. In engineering step, the selection and adjustments of TC curves shall be done

for the protection coordination with other protection devices in the feeder.

The follwing parameters are related to change and editing of TC curve’s characteristics.

ü Time Multiplier

ü Time Adder

ü Minimum Response Time

Time Multiplier is multiplied to the operating time of basic curve (TDM=1.0), then Time Adder is added

to the resulting operating time of the curve adjusted by multiplier. Minimum Response Time defines the

fastest operating time of the curve.

The following tables describe the built-in TC Curve Type and the corresponding numbers in the setting.

13.1.5 EXAMPLE OF TC CURVE EDITING

3-parameters are applied in the follwing order. The values in the parenthesis are examples.

ü Time Multiplier : 1.5

ü Time Adder : 0.03

ü Minimum Response Time : 0.1

In the next figure, for example, the curve A is the basic curve. Assume the operating time of the

basic curve (A) at 16 times pickup current is 0.04 sec. When applying Time Multiplier, curve ‘A’

changes its shape, that is, the curve becomes less steep in t ime axis and operat ion

time becomes longer by a multiplier at the same current value like ‘B’ in the figure. The operating

time at 16 times pickup becomes 0.06 sec. Then Time Adder shall be applied. The operating time

of the resulting curve ‘C’ is 0.09sec. Finally Minimum Response Time cuts the curve part, which is

shorter than this time. Then the actual operating time of the example at 16 times becomes 0.1sec.

[ TC Curve Editing Example 1 ]

There are two additional definite time over-current elements in the controller. The next figure shows 3-

stage over-current protection characteristics. The third stage is prepared for instantaneous protection.

Therefore the harmonic restraint is not applied to third stage elements, but the second stage definite

time over-current element.



[ TC Curve Editing Example 2 ]

13.1.6 AUTO RECLOSING SEQUENCE

The FTU-R200 supports 3-shot reclosing with sequence coordination.

For Permanent fault, under the condition of reclosing enabled, no other restraints such as cold-load,

inrush and no High Current Trip, recloser will be locked out to open the Reclosing Count repeating trip

and reclose according to the preset settings.


Phase

Operation Count 1~4 4 1

Instantaneous Count 0~4 2 1

Earth


Instantaneous Count 0~4 2 1

Phase/ Earth Reclosing

Reclose Interval 1st 0.5~180 0.6 0.1 sec

Reclose Interval 2nd 1~180 2 1 sec

Reclose Interval 3rd 1~180 15 1 sec

Reset Time 3~180 30 1 sec



SEF Reclosing


Reclose Interval 1st 0.5~180.0 0.6 0.1 sec

Reclose Interval 2nd 1~180 2 1 sec

Reclose Interval 3rd 1~180 15 1 sec

Reset Time 3~180 30 1 sec

For example in the below figure, the reclosing sequence is organized in 2F2D, which means

the Recloser protection function operates as Instantaneous(Fast) element during first 2 reclosing shots

and operates as Time-Delayed element during last 2 reclosing shots. This composition also can be

configured.

[ Permanent Fault: 3 shot Reclosing & 2F2D ]

For temporary fault, if the fault is removed before the preset Reclosing Count and no fault is detected

during the preset Reset Time, then the reclosing sequence is initialized to normal operation standby

mode. When a fault is detected again during the Reset Time, the Recloser will be locked out after the

remaining reclosing counts excluding the previously operated reclosing counts.



[ Temporary Faults: Fault Removal during 1st Reclosing Interval ]

13.1.7 SEQUENCE COODINATION

In case that there are over 2 Reclosers which operate in serial connections, Sequence Coordination

function prevents unnecessary trip of source-side Recloser by instantaneous element due to load-side

fault. When this function is set to on and the fault is restored to normal state by load-side Recloser

during source-side Recloser’s time-delayed operation, source-side Recloser only increments the

reclosing counts without tripping. However, source-side Recloser performs tripping at the last reclosing

count. If the Reclosing function is disabled, Sequence Coordination function is no longer carried out.


Seq. Coordination Active OFF/ON OFF

For Sequence Coordination, the following setting items should be issued and checked precisely between

serially connected Reclosers.

ü Identical Protection Characteristics such as TC Curves, Total Operation Count,

Instantaneous Operation Count

ü Identical Reclosing Interval(Dead Time)

ü Source-side TC Curve Time Delay Over 100msec than Load-side

ü Source-side Reset Time longer than Load-side longest Reclosing Interval

(to Prevent Source-side Recloser reset during Load-side Reclosing action)



[ Operation of Sequence Coordination ]

13.2 COLD LOAD PICKUP

Cold Load Pickup is the phenomenon that takes place when a distribution circuit is re-energized

following an extended outage of that circuit. Cold load pickup is a composite of two conditions: inrush

and loss of load diversity. The magnitude of cold load pickup current is a combination of non-diverse

cyclic load current, continuously operating load current, transformer magnetizing current, capacitor

inrush current, etc. The combination can result in current levels that are significantly higher than normal

peak load levels. Cold load pickup current can be high enough to cause instantaneous overcurrent

and/or time overcurrent relays to operate.

Cold load pickup is primarily an overcurrent condition. If degraded voltage is also a concern, then the

application of voltage sensitive relays should also be considered.



[ Cold Load Pickup Current Shape ]

In Cold Load Pickup mode, without changing operational characteristics, pickup level is changed by the

times of Cold Load Multiplier (0~10) and the characteristics of time-delayed element operate even if the

setting is in the Instantaneous element. If the transient current goes down and retrains below the pickup

level within Cold Load Duration, then the normal sequence mode is restored after Cold Load Restore

Time. The Cold Load Restore Time is fixed value of 30msec. These setting exist for both phase fault and

earth fault separately, and the value ‘0’ of Cold Load Multiplier means Cold Load Pickup Function

disabled. Normaly Reclosing Sequence mode is applied.


Phase Detection

Pickup Multiplier 0~10 2 1 ‘0' means disable.

Duration Time 0.00~60.00 3.00 0.01 sec

Earth Detection

Pickup Multiplier 0~10 2 1 ‘0' means disable.

Duration Time 0.00~60.00 3.00 0.01 sec



13.3 SENSITIVE EARTH FAULT(SEF) DETECTION

On the non-grounded network, it is hard to detect fault current because ground current of non-

grounded network is much low. Therefore, FTU-R200 is designed to measure zero-sequence values from

either external core Balanced Current Transformer (or ZCT) or Residual Connection of 3 Phase Current

Transformers to detect earth fault in the non-grounded network. This function is generally called SEF

detection.

In case of earth fault in the non-grounded network, since very small fault current due to line

capacitance component flows into the fault point from both sides, SEF detection also considers the fault

direction even in the radial network. Maximum Torque Angle is for setting the phase difference between

zero-sequence voltage and zero-sequence current, and the protection zone is between -90° and +90°

on the basis of Maximum Torque Angle. And it can be used for alarm or Trip.

[ Phase Diagram of SEF ]



13.4 DIRECTIONAL BLOCKING

Directional Blocking is a protection feature that restricts tripping on faults to a designated side of the

recloser. It prevents nuisance tripping if particular network conditions are causing ‘False’ earth faults. In

radial systems Directional Blocking prevents nuisance tripping by blocking faults in the reverse direction

and only responding to faults in the foward direction.

Protect for faults in the forward and reverse direction. A forward fault may use a different time-current

curve and setting to a reverse fault (i.e. these are individually selectable). Both the forward protection

and reverse protection are operating at the same time. This is an additional protection feature.

13.5 INRUSH RESTRAINTS

Inrush Restraint works by raising the phase and earth currents for a short period of time to allow the

inrush current to subside.

Inrush current is an over-current higher than pickup current level, which is mainly caused by

transformer’s excitation current at closing action. To distinguish inrush current from load current, 2nd

harmonics percentage is adopted as a criterion.

When, in the setting, ‘Fault Detection-Inrush Block’ is set to ‘Yes’ and ‘Fault Detection-Inrush

Detection-Function In Use’ is set to ‘ON’, inrush current over pickup level is considered as normal load

current and reclosing sequence is not processed.

This Function can be used to detect magnetizing inrush condition by comparing 2nd harmonic

component to fundamental frequency component of current.

13.6 OPEN LINE DETECTION(LOSS OF PHASE)

Open Line is detected by Under Voltage characteristics at unbalanced condition.

When the voltage on one or two phases drops below the ‘Volt OFF Level’ setting, the ‘Delay Time’ starts

running. If the voltage on those phases stays below ‘Volt OFF Level’ setting until the ‘Delay Time’ timer

expires, the Loss of Phase will be detected.

If the voltage on detected phase rises to the ‘Vol ON Level’ setting, the Loss of Phase is released

immediately.

13.8 UNDER VOLTAGE PROTECTION

As the supplied voltage to load lowers down, there occur the weakness of illumination intensity and

shortening of life span for lighting load, and the damage to motors because of the over-current flow. To

cope with this situation of damages to equipment, under-voltage protection (UV) is used. UV of FTU

supports the delay time element. Furthermore, UV can be used to generate only alarm signal to

operator instead of trip signal to Recloser.

On the other hand, as the supplied voltage goes up behind the regular load voltage, there occur some

problems of equipment deterioration, insulation breakdown, equipment life span shortening, etc. Over

Voltage Protection (OV) manages this situation. OV of FTU supports the delay time element. OV also

can be used to generate only alarm signal to operator instead of trip signal to Recloser.

13.10 UNDER FREQUENCY PROTECTION

Under Frequency protection (UF) element is used into expenditure that detect under frequency and

separated load or generator. Under Frequency demands for power increase or occurs in control failure

of generator.

Under Frequency protection element acts in case of voltage more than ‘Voltage OFF Level’ is approved

to Voltage A-Phase. UF of FTU supports the delay time element. Furthermore, UV can be used to

generate only alarm signal to operator instead of trip signal to Recloser.

13.11 MULTIPLE PROTECTION GROUPS

The FTU-R200 supports up to 4 Protection Groups, each of which can be confiqured with completely

separate protection characteristics with different inverse time curves and setting currents. The number of

protection group avaliable to the operator can be configured.

And FTU-R200 support Automatic Protection Group Selection. Automatic Protection Group Selection is

used to change the protection group depending on the direction of power flow. This allows the

Recloser to be correctly graded with devices downstream regardless of the power flow direction.

14.1.2 SWITCH INSTALLATION

The FTU-R200 provides a function to set ‘Reference Phase’ and the ‘CT Direction’ according to

the switch installation position and the current flowing direction.

The following figure shows the general and ‘assumed-default’ case of switch installation, in which the

distribution lines with current A, B, C are connected to the phase A, B, C terminals of the switch, and the

current is flowing A/B/C to R/S/T of the switch. In this case, the ‘Referece Phase’ setting value should

‘A’, which means that the phase of current flowing into the phase A terminal of the switch is ‘A’, In

addition, the ‘CT Direction’



setting value should be ‘Foward’, which means that the current is flowing in the direction from the

phase A/B/C terminals to the R/S/T terminals of the switch.

[ Switch installation position and the current flowing direction - Case 1 ]

The following figure shows another case of switch installation, in which the distriburion lines with

means that the phase of current flowing into the phase A terminal of the switch is ‘A’, In addition, the

‘CT Direction’ setting value should be ‘Reverse’, which means that the current is flowing in the

14.2 POWER QUALITY MEASUREMENT FUNCTION

14.2.1 VOLTAGE & CURRENT UNBALANCE

Voltage unbalance (or imbalance) is a condition in which the maximum deviation from the average of

the three-phase voltages or currents, divided by the average of the three-phase voltage or currents,

expressed in percentage. Voltage unbalance can be the result of blown fuses in one phase of a three-

phase capacitor bank. Severe voltage unbalance greater than 5% can cause damage to sensitive

equipments.

14.2.2 SHORT-DURATION VOLTAGE VARIATION

There are three types of short-duration voltage variations, namely, instantaneous, momentary and

temporary, depending on its duration. Short-duration voltage variations are caused by fault conditions,

energization of large loads, which require high starting currents or loose connections in power wiring.

Depending on the fault location and the system conditions, the fault can generate sags, swells or

interruptions. The fault condition can be close to or remote from the point of interest. During the actual


Voltage Unbalance

Detection Level 0~100 30 1 %


Current Unbalance

Detection Level 0~100 30 1 %




fault condition, the effect of the voltage is of short-duration variation until protective devices operate to

clear the fault.

14.2.2.1 SAG

A sag (also known as dip) is a reduction to between 0.5 and 0.99 pu in RMS voltage or current at the

power frequency for a short period of time from 0.5 to 10 cycle. A 10% sag is considered an event

during which the RMS voltage decreased by 10% to 0.9 pu. Voltage sags are widely recorgnized as

among the most common and inportant aspects of power quality problems affecting industrial and

commercial customers. They are particularly troublesome. Since they occur randomly and are difficult to

predict.

Volatge sags are normally associated with system faults on the distribution system, sudden increase in

system loads, lightning strikes or starting of large load like induction motors. It is not possible to

eliminate faults on a system. One of the most common causes of faults

occuring on high-volatage transmission systems is a lightning strike. When there is a fault caused by a

lightning strike, the voltage can sag to 50% of the standard range and can last from four to seven cycles.

Most loads will be tripped off when encounter this type of voltage level. Possible effect of voltage sags

would be system shutdown or reduce effciency and life span of electrical equipment, particularly motors.

Equipment sensitivity to voltage sag occurs randomly and has become the most serious power quality

problem affecting many industries and commercial customers presently. An industrial monitoring

program determined an 87% voltage disturbances could be associate to voltage sags. Most of the fault

on the utility transmission and distribution system are single line-to-ground faults (SLGF).


Detection Level 0.50~0.99 0.90 0.01 PU

Detection Time 0.5~10.0 2.0 0.5 Cycle

14.2.2.2 SWELL

A swell (also known as momentary overvoltage) is an increase in RMS voltage or current at the power

frequency to between 1.01 and 1.5 Pu for duration from 0.5 to 10 cycles. Swells are commonly caused

by system conditions, switching off a large load or energizing a large capacitor bank. A swell can occur

during a single line-to-ground fault (SLGF) with a temporary voltage rise on the unfaulted phases. They

are not as common as voltage sags and are characterized also by both the magnitude and duration.

During a fault condition, the severity of a voltage swell is very much dependent on the system



impedance, location of the fault and grounding. The effect of this type of disturbance would be

hardware failure in the equipment due to overheating.




14.2.2.3 INTERRUPTION

An interruption occurs when there is a reduction of the supply voltage or load current to between 0.1

and 0.49 pu for duration from 0.5 to 10 cycle. Possible causes would be circuit breakers responding to

overload, lightning and faults. Interruptions are the result of equipment failures, power system faults and

control malfunctions. They are characterized by their duration as the voltage magnitude is always less

than 10% of the nominal. The duration of an interruption can be irregular when due to equipment

malfuctions or loose connections.

The duration of an interruption due to a fault on the utility system is determined by the utility

protective devices operating time.




14.2.3 VOLTAGE & CURRENT ALARM

The Total Harmonic Distortion, or THD, of a sigmal is a measurement of the harmonic distortion present

and is defined as the ratio of the sum of the powers of all harmonic components to the power of the

fundamental frequency.

15. STATUS MONITORING & CONTROL

15.1 SWITHCH CONTROL

Recloser can be controlled from remote or local operator place. Operator place can be changed only at

local front panel. ‘REMOTE CONTROL’ push button is to select the operator place. Operator place is

toggled between local and remote by pushing button. LED is lit if remote position is selected. FTU-R200

begins with remote position at power-up. Control is allowed only at the position selected.

Local switch control requires two-step operation. It’s for security of operation. ‘SELECT’ button should be

pushed before ‘CLOSE’ or ‘OPEN’. SELECT LED is lit if SELECT operation is valid. SELECT can be canceled

by pushing SELECT button again or automatically after SBO timeout without operation. CLOSE or OPEN

operation is valid while this LED is lit. Pushing CLOSE or OPEN button outputs switch control signal with

fixed time pulse which is configurable. Switch status change input which is auxiliary contacts of switch

stops continuing to output pulse. There are some interlock conditions to inhibit FTU from outputting

pulse signal.

Gas low, Switch handle lock, same status of switch auxiliary contacts ‘a’, ‘b’ are those. Close or open

pulse width shall be set longer than switch operating time.

Remote switch control is possible by using SCADA protocol DNP3.0 or IEC60870-5-101, IEC60870-5-104

FTU-R200 supports SBO (Select Before Operate) or Direct operate. If the operator place is set to ‘Local’,

remote control commands are refused. Pulse width of remote control command shorter than setting will

be overridden by local configuration

15.2 SWITCH STATUS MONITORING

FTU monitors switch open/close, gas and lock status through auxiliary contacts. FTU scans these

contacts input every 5 milliseconds. Switch open/close status is determined by double binary input,

normally open and closed contacts. Changes of all input status are saved as events with time tag in

history buffer. For each contact input, on-delay time can be applied. It’s adjustable within 10~500ms by

5ms step.

15.3 BATTERY MONITORING

FTU monitors external Lead-acid battery through the control unit, which are mounted on inner back-side

of control box. Battery voltage is supervised continuously during external AC supply loss. If over-

discharge condition occurred, the control unit sends alarm signal to RTU and disconnect battery in order



to protect battery cell damage after 1-minute delay. The delay enables RTU to send alarm state to

remote station via communication. Also while AC supply is applied, battery test control activates this

function with connecting dummy battery load during test pulse, which is configurable. The test control

command can be ordered at local or remote.

16. MEASUREMENT

16.1 BASIC ELECTRIC QUANTITIES

FTU has 3-phase currents and 6 voltages input. DSP digitizes these signals and calculates various electric

quantities. These are basically based on fundamental frequency components. DSP use FFT (Fast Fourier

Transform) algorithm to get the components. Also DSP calculates true RMS of 3-phase currents and

voltages which include system frequency components and 2nd~31th harmonics. Actually harmonic

components over than 31th are attenuated by analog filters. Electric quantities calculated are listed in

the following.

l Currents (Ia, Ib, Ic, In) RMS, Phase Angle, True RMS

l Voltage (Va, Vb, Vc, Vr, Vs,

Vt)

RMS, Phase Angle, True RMS

l Apparent Power A-Phase, B-Phase, C-Phase, 3-Phase Total,

l Active Power A-Phase, B-Phase, C-Phase, 3-Phase Total,

l Reactive Power A-Phase, B-Phase, C-Phase, 3-Phase Total,

l Power Factor A-Phase, B-Phase, C-Phase, 3-Phase Total,

l Va-Vr Phase Angle Difference

l Current, Voltage Unbalance

l Frequency, Temporature

In the above items listed, active power, reactive power values are signed integer. Sign represents power

flow or if loads are inductive or capacitive. Also power factor has lead/lag state value separately.

Currents and voltages have phase angles, which are relative phase angles compared to the reference Va.

These angles are useful to monitor the phase sequence and imbalance of distribution line.

16.2 SEQUENCE COMPONENTS

FTU provides the sequence components of 3-phase currents and voltages. They are positive sequence

current (I1) and voltage (V1), negative sequence current (I2) and voltage (V2), and zero sequence voltage

(V0) which are calculated by 3-phase phasor quantities. This information can be used to monitor

imbalance of distribution line.



16.3 HARMONICS

FTU extracts harmonic components from 3-phase current and voltage signals by using FFT (Fast Fourier

Transform). It provides 2nd to 31st harmonic magnitudes and THDs (Total Harmonic Distortion) for each

phase. THD is the total harmonic percentage to the fundamental frequency component. FTU also

calculates and provides 3-phase THD. These values may be used to monitor the power quality of

distribution line.

16.4 ENERGY

FTU provides active energy, reactive energy for each phase or 3-phase total. Also import, export energy

are accumulated on separate register. Units of energy are kWh, kVarh, which represent primary

distribution line energy flow. The values are represented by 16-bit rollovers kWh, kVarh counters which

are available at remote or local. Power calculation for energy is based on the fundamental frequency

component. It’s not for billing purpose, but for load management. Proper energy accumulation needs

that SCADA read energy counter with reset from FTU and accumulate it on SCADA’s local register by

periods shorter than the expected rollover time of the counter.

[Four-quadrant power flow directions ]

16.5 DEMAND CURRENTS AND POWER

FTU calculates and stores average of currents and active, reactive powers during the demand interval,

which is configurable as 5, 10, or 15 minutes. The buffer has 1023 demands. Also FTU stores daily peak

demand up to 1023.

the commas of its set.

Each line in the CSV file corresponds to a row in the table. Within a line, fields are seperated by

commas, each field belonging to one table column. Since it is a common and simple file format, CSV

files are often used for moving tabular data between two different computer programs, for example

between a database program and a spreadsheet program.

18. I/O CONFIGURATION TOOL

18.1 OVERVIEW

The ‘IO Config’ tool allows FTU users to custom I/O mappings.

[ Overview of IOConfig Tool ]

The I/O mapping is created using the tool and saved to an IO File (*.iom). Once a valid file has been

created, it is linked to the Recloser device.

The IOConfig tool is intended to be used off-line only. Mappings are created, saved and linked to

FTUMan while disconnected from the FTU. Once these tasks have been completed the user connects to

the device and writes the new mapping into the Recloser.

Warning: Make sure the IOConfig Tool is closed after a mapping has been edited. If the Tool is left

open while the Automatic Data Retriaval feature is running it may attempt to update a mapping file that



is already open in the Tool. This will either cause the read operation to fail or result in a situation where

the newly read file differs from the file open within the Tool.
