The kind of energy and power measured is specified by the meter configuration.

The meter may be used in AMR system for data transmission to the electric energy control, metering and distribution dispatch center. For establishing AMR systems interfaces (pulse outputs, EIA232, EIA485) may be used.

Measurement results are drawn by the meter mother board microprocessor circuit processing and calculating the voltage and current incomers. Mezzanine boards installation, depending on the modification, allows extending the meter capabilities. The data acquired and other information is displayed on the LCD.

The meter has an electronic register that accomplishes, depending on the current and voltage transformation ratios set, metering of active, reactive electric energy, energy loss in one or two directions (kWh, MWh, GWh, kVArh, MVArh, GVArh correspondingly).

The time of the variation in the register indication complies with GOST R 52322-2005 (GOST R 52323-2005), GOST R 52320-2005 and GOST 26035-83, IEC 62053-23:2003 requirements.

Figure 3.5 Structural diagram

3.5.2.1 The basic printed-circuit board AC line currents and voltages are measured by special current sensors (transformers) and resistance dividers accordingly. Value conversions are accomplished by using six-channel analog-to-digital converter (ADC) that fulfils analog-to-digit conversion of input signals instantaneous amplitude and transmission via serial synchronous interface to MC. ADC digital code values come into serial synchronous microcontroller (MC) port. MC accomplishes calculation of currents and voltages, active, reactive, apparent powers and energies, and also displacement angle and voltage signal basic frequency meansquare values. MC makes connection between all the peripheral units. The basic electronic meter elements are installed on the same printed-circuit board:

3.5.2.2 Power module To supply the meter with power pulse reverse converter, converting rectified input

voltages into the voltage necessary for supplying all the meter blocks and modules with power, is used. To supply the meter with power from the back-up power source (BPS) low-voltage reverse converter to which the back-up power voltage (915 V) may be supplied. In the input voltages UA, UB, UC absence the meter automatically switches to the BPS operation (if the back-up power is supplied). In the input voltages UA, UB, UC presence the BPS automatically switches off.

The BPS input circuits are galvanic isolated from the other circuits and endure 4 kV breakdown meansquare voltage.

3.5.2.3 Voltage transducers To match phase voltages with ADC input amplitude levels the resistance dividers are

used. Phase (phase-to-phase) voltages are supplied from PM via the upper divider arm resistors

to the basic printed-circuit board, where the lower divider arm resistors are installed and led up to the input signal level required for ADC. Metal-film resistors with minimum temperature coefficient are used in the dividers.

3.5.2.4 Current transducers Electronic circuit diagram receives each phase current via meter-mounted current

transformers. Transformer secondary sides are load resistance connected, as a result the voltages proportional to input currents are supplied to ADC inputs.

3.5.2.5 Signal conversion and computation ADC measures the instantaneous values proportional to phase voltages and currents via

six channels parallel, converts them into the digital code and transmits them via the high-speed serial data link to the MC calculating machine.

By sampling voltage and current instantaneous values the MC calculating machine calculates mean values for the period of measuring the required values considering the calibration factor according to the following formulas:

Figure 3.6 Active and reactive energy (power) quadrant distribution diagram

For each of the calculating machine six channels, configured for certain energy types

computation, per-phase values, integrated in the period of 1 sec., are calculated: - of active energy (power) import, Ai, if the phase apparent power phasor is in the I or IV

quadrants; - of active energy (power) export, Ae, if the phase apparent power phasor is in the II or

III quadrants; - of reactive energy (power), R1 (R2, R3, R4), if the phase apparent power phasor is in

the I (II, III, IV) quadrants correspondingly; - of import (export) active energy (power) loss, Li (Le), if the phase apparent power

phasor is in the I or IV (II or III) quadrants correspondingly. On the basis of the calculating machine channels calculated energies MC transmits

energy consumption signals to the pulse outputs (in case they are configured as telemetry outputs), which may be connected with AMR system.

4.5.4 Connect the power source holder plug to the meter and put it in its place. Note To avoid clock inaccuracy while the power source replacement, the activities

mentioned above should be completed with the meter in operation. 4.6 The meter configuration The meter programming and reading is accomplished with AMR system or PC (with the

TSW Administration program installed) via one of the interfaces by using a corresponding adaptor or via the optical port by using the optical head in accordance with GOST R IEC 61107-2001 or IrDA 1.0. Data formats for the interface exchange are given in Annex E.

While the meter programming, the date, time, access passport and parameters list are fixed in the programmable parameters log. Additionally, in some parameter group recorders the date, time, access password and the given group programming quantity are fixed.

In the identification message line the meter outputs: manufacturer identification code EKT product identification code CE304vX, where X meter data set version.

The meter programmable parameters typical configuration: calculating machine channels depending on type (CL 4.6.1); external current and voltage transformers transformation ratios 1; phase wires resistance 1 Ohm; calculating machine channels power averaging time period 30min; calculating machine channels power averaged limits 0 (are not set); voltage fluctuation upper (lower) boundaries 120 (80) % of UNOM; time-of-day pulse output control switches 0 (are not set); pulse outputs 1, 2,3, 4 - calculating machine channels 1, 2, 3, 4 energy telemetry meander; pulse outputs 5, 6 direct control, dead condition; pulse inputs switched off; pulse inputs constants 1; pulse inputs transformation ratios -1; rate scale not set; profile configurations not set; time Moscow; summer (winter) time switch months March, (October); access password #1 -777777; other passwords not set; the meter address-identification code not set; initial interface exchange rate 300 bauds; operating interface exchange rate 9600 bauds; interface activity time 4s; response delay time 200 ms; programming authorization with the ACCESS button; accumulated energy reset with buttons unauthorized; consequent same name parameters outputting into interface without a name allowed; indication automatic return allowed. The full list of programmed parameters and their values is given in TP. 4.6.1 Calculating machine channels configuration (KANzz)

The meter allows programming six calculation channels for different energy (power) types calculation:

both directions (Ai, Ae) active energy (power); four quadrants (R1, R2, R3, R4) reactive energy (power); both directions energy (power) loss (Li, Le); external measuring element unit-counting input physical quantity values (11, 12,

13, 14). Energy (power) proportional to telemetry pulses of the external electricity meters

connected to unit-counting inputs may be grouped in one calculation channel with meter own measurements.

ATTENTION! To avoid incorrect data formation only identical in energy (power) type are allowed to be grouped in the calculation channels.

ATTENTION! To avoid incorrect indication of previously metered energies and powers, after calculation channels reprogramming it is necessary to reset accumulated energies and load profiles.

For unidirectional meter: The first calculating machine channel is always programmed for total active energy

calculation (Ai + Ae). Consequently, energy will be metered via this channel independently of energy flux direction.

For bidirectional meter: The first calculating machine channel is always programmed for imported active energy

calculation (Ai). Consequently, phase energy with positive active power (P+, quadrant I or IV) will be metered via this channel.

The second calculating machine channel is always programmed for exported active energy calculation (Ae). Consequently, phase energy with negative active power (P-, quadrant II or III) will be metered via this channel.

Other five or four calculating machine channels may be programmed for various energy (power) types calculation to meet Customers requirements.

Example: - total active energy metering (for bidirectional meter); - imported reactive energy metering; - exported reactive energy metering; - total energy loss metering, or - imported reactive energy metering; - exported reactive energy metering; - energy loss metering for imported active energy; - energy loss metering for exported active energy. For active energy (power) import metering and control accomplished by the enterprise that

has some lead-in feeders (three), it is necessary to install CE304 meter with pulse input module into one feeder. Simple active energy meters shall be installed into other feeders (two) and their main transmitting unit outputs shall be connected to pulse inputs (PI1, PI2). Pulse inputs shall be programmed in accordance with connected external meter parameters (constants and transformation ratios). Calculating machine channel #4 shall be programmed for imported active energy and unit-counting input energies (Ai+11+12) calculation.

Typical configuration of calculating machine channels is given in Table 4.1 Table 4.1

Measured and stored values of Calculation channel unidirectional meter bidirectional meter

Channel 1 Ai+Ae always Ai always Channel 2 R1 Ae always Channel 3 R4 R1+R2 Channel 4 Li+Le R3+R4 Channel 5 Ai Li Channel 6 R1+R2+R3+R4 Le

4.6.2 Calculation results reduction to input end (FCCUR, FCVOL) The meter can accomplish input end calculation considering measuring current and voltage

transformers transformation ratios. Calculated energy and power values and also network quality parameters are automatically multiplied by voltage transformer transformation ratio (Rv) and current transformer transformation ratio (Rc) in metering point. In this case measured values displayed on LCD and transmitted via digital interfaces indicate measuring transformers input end values.

The meter operation light indicators (LI) and pulse outputs in telemetry mode indicate energy without considering Rv and Rc.

For the meter direct connection or obtaining the output end (meter terminals) measurement results, it is necessary to set transformation ratios Rv=1, and Rc=1.

4.6.3 Electric main phase wires resistance (RESzz) The meter can accomplish calculation energy (power) loss in electric main wires for each

phase. To do this, it is necessary to set each controlled line segment phase wire resistance. Calculation of active power loss in wires is accomplished by the formula P=I2R.

4.6.4 Power averaging time interval (TAVER) Calculating machine channel power averaging time interval for commercial metering may

be set in the range of 160 min. interval duration is chosen from the range: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 minutes.

Each calculating machine channel power, averaged in a set interval, is used: For each tariff maximum power finding and fixation during a month; For set power limit exceedence finding per tariff.

4.6.5 Averaged power limits (LIMzz) For each calculating machine channel and each tariff their own limit of power averaged in

a set interval may be set. Average power limit value is set in kW (kVAr) considering transformation ratios Rv and Rc used (reduction to input end). For average power limit value equal to zero, power limit exceedence verification is not taken.

4.6.6 Phase voltage fluctuation boundaries (LEVUP, LEVDN) For event fixation in fluctuation log and signal formation at pulse output in case of

measured voltage value limit exceedence, upper and lower boundaries of accepted fluctuation are set in percents of nominal voltage. Value range 0130%.

Phase voltage failure finding boundary is fixed and comprises 5% of nominal voltage. 4.6.7 Time-of-day pulse output control switches (TMTzz) The meter has four independent time-of-day pulse output switches. Any available rate

scale is fixed for each switch. Pulse output will be in dead mode during tariff #1 operation time of day and in closed mode during tariff #2 operation time of day. Any other scale tariff doesnt cause pulse output mode switch.

4.6.8 Pulse outputs configuration (TELzz)

The meter allows programming of up to eight pulse outputs (TM1TM8) for various verification or control signals formation. Each pulse output is set individually and allows commuting circuits of external devices with electrical pulse output set module characteristics. Each pulse output may be set for performing the following functions:

calculating machine channel test output unit (telemetry); set calculating machine channel power threshold exceedence response; set time of day response; current tariff response; phase voltage response; direct control by a command via interface; the basic quartz-crystal resonator test. The list of functions (events) for pulse output is given in Table 4.2

4.6.8.1 Calculating machine channel test output unit (telemetry) In this mode pulses appear at the output with the frequency proportional to a set

calculating machine channel energy quantity without considering transformation ratios of current, voltage, pulse input transformers in the metering point. The meter constant pulse quantity for kWh (kVAr), is determined by meter modification according to Table 3.3.

For pulse output operation in telemetry mode it is necessary to: set the number from the list of functions (calculating machine channel choice); set the required telemetry pulse duration from 1 to 127 ms or meander; set the telemetry pulse active level dead or closed. Pulse output in telemetry mode is usually used for meter verification.

4.6.8.2 Set calculating machine channel power threshold exceedence response While performing this function, calculation of assessed mean power of calculating

machine channel is used. Assessed mean power is the power averaged from the beginning of the averaging interval up to the current time. It informs about the energy flux tendency in a set interval and serves for indication of the set power level (limit) exceedence in a set averaging interval.

Assessed power limit exceedence verification for the current tariff is accomplished every minute of the averaging interval.

In this mode pulse output will be in dead condition during the first minute of the averaging interval. Every next minute pulse output switches to the mode:

closed at developing assessed power of power limit; dead at assessed power value below power limit. The function is used for the power limit exceedence indication or as a load control relay. For pulse output operation in this mode it is necessary to: set the number from the list of functions (calculating machine channel choice); set the calculating machine channel power limit for tariffs controlled. 4.6.8.3 Set time of day response While performing this function rate scale is used. The meter has four independent time-

of-day pulse output switches. Any rate scale is fixed for each switch. Pulse output will be in dead mode during time of day when tariff #1 is active and in closed mode during time of day when tariff #2 is active. Any other scale tariff doesnt cause pulse output switch.

The function is used for control instruction issue in a set time of day. For pulse output operation in this mode it is necessary to: set the number from the list of functions (switch choice); schedule tariff #1 and tariff #2 day switch; set the number of rate scale for the switch chosen (TMTzz). 4.6.8.4 Current tariff response Each pulse output may be fixed for any of four tariffs operation time indication. Pulse

output will be in closed mode during the fixed tariff operation and in dead mode during the rest of the day. The function is used for tariffication instruction issue to the external nontariff devices.

For pulse output operation in this mode it is necessary to: set the number from the list of functions (tariff choice). 4.6.8.5 Phase voltage response Each pulse output may be fixed for one of the phase voltage modes indication: any phase voltage is absent; any phase voltage is less than a set low level; any phase voltage is more than a set upper level. Phase mode information refreshment is accomplished once a second. The function is used for bad quality network indication. For pulse output operation in this mode it is necessary to: set the number from the list of functions (controlled mode choice). 4.6.8.6 Direct control by a command via interface Each pulse output may be fixed for indication of the mode set via interface. The function is used for remote external devices control. For pulse output operation in this mode it is necessary to: set the number from the list of functions (control choice);

set the required output mode (TMDIR). 4.6.8.7 The basic quartz-crystal resonator test. Each pulse output may be fixed for issue of meander with a period of 10 sec. proportional

to the basic quartz-crystal resonator frequency. The function is used for verification and calibration of the basic quartz frequency

technological parameter. For pulse output operation in this mode it is necessary to: set the number from the list of functions (test choice). 4.6.9 Pulse inputs configuration (INMzz, INCzz, INSzz) The meter allows programming four pulse inputs (PI1PI4) for external sensors pulses

calculation with their successive conversion into named units. Those sensors can be represented by particularly electricity meters, utility meters with pulse outputs. Also pulse input may be used for events quantity calculation and receiving information on connected mechanical burglar and fire alarm sensors condition.

Pulse quantity metering mode is set individually for each input: no metering; by closed to dead state transition leading edge; by dead to closed state transition trailing edge; by both edges. To avoid metering afterpulses, caused by short spurious signals at pulse input connection

diagrams, input filter constant is set in the range of 1255 ms. Pulses with the length less than filter constant will be hidden for the meter.

For the named physical quantities calculation by the unit-counting inputs the external meter constant is entered. That meter transmits pulses proportional to measured value to the basic transmission unit as pulse quantity per kWh (kVArh, m3). To reduce energies (powers), designed for electricity meters, to input end, power transformation ratio is set external meter voltage and current transformers transformation ratios generation.

Named values calculation is accomplished only for pulse inputs included in calculating machine channel.

Quantity of pulses metered per each input may be reset only while accumulated energies resetting.

For pulse input configuration it is necessary to know: pulse metering mode; afterpulse length; inverting input constant (for named values); generalized transformation ratio (for named values). 4.6.10 Multirate mode configuration The meter accumulates calculating channels energies: under four tariffs; under additional tariff, in case it is impossible to define the current tariff (real time

clock inaccuracy or rate scale is not set); under all the tariffs in total (unrated metering). The meter averages calculating machine channel powers in a set time interval and fixes

month power maximum value: under four tariffs; under additional tariff. For multirate metering organization it is necessary to set: day rate scales list;

day of week season structures and season beginning dates; exceptional days (days when tariffication is different) list. 4.6.10.1 Day rate scales list (GRFzz) It is possible to set up to 15 current tariff switch time within a day period. The switch

time rating period beginning is set with accuracy to 1 min. During one time of the day only one tariff can be active. Certain tariff is active during the set time till switch time period. In case the basic switch time is defined not from the day beginning the tariff defined for the latest time of day is active.

The example of rate schedule is given in Table 4.3 and in Figure 4.9 Table 4.3

Figure 4.9

To set one tariff for the whole day its sufficient to specify any time of day. The meter allows setting of up to 36 different day rate scales (rate scale list).

4.6.10.2 Season structure (SEASON) The season determines fixed tariffication for the time period from a day to a calendar

year. The time of season activity is defined from the specified date of season beginning till the beginning of the next season in a calendar year. In case the season with the date of calendar year beginning is absent in the list of seasons the last set season is active from the beginning of the year. Within the time period during which the season is active the tariffication per weekday remains unchanged. Certain rate scale may be set for each weekday.

The example of a calendar year rate schedule is given in Table 4.4. Table 4.4

In this example the year is divided into two seasons. Since the 1st of January till the 4th of April and since the 12th of October till the 31st of December the second season rate scales will be active, since the 5th of April till the 11th of October the first season rate scales will be active.

The meter allows setting of up to 12 season rate scales. 4.6.10.3 Exceptional days (EXDAY) Exceptional days are days of a calendar year the tariffication of which is different from

the season weekday tariffication. Such exceptional days are public holidays, holidays and workdays rescheduled. Any rate scale of the list prepared may be specified for each exceptional day.

The meter allows setting of up to 32 exceptional dates. 4.6.11 Profiles configuration The meter allows forming of up to 16 independent profiles. The data accumulated in

profiles are accessible only via digital interfaces. A profile can accumulate the energy (power) data of any calculating machine channel with the individual time interval. The profile data values are reduced to input end and registered considering the active transformation factors. For the meter switched off during a day profile data for that day is absent. For the meter switched off during an interval time that interval data is marked as absent. In case the interval is changed by the time correction or the meter is switched off in the interval segment the data is marked as incomplete. For each profile it is possible to set:

calculating machine channel; data type energy or power; time interval in the range: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 min. The profile configured for the calculating machine channel #0 or with the interval time 0

min is considered switched off. ATTENTION! While profile configuration logging into the meter all the previously

accumulated profile data is reset. Any profile data storage period depends only on time interval and is defined in

accordance with Table 4.5 Table 4.5 Time interval, minutes

1 2 3 4 5 6 10 12 15 20 30 60

Storage period, days

11 22 33 44 56 67 112 134 168 224 336 512

4.6.11.1 Profile data formation at clock time change In case the time is put forward (analogous to switching the meter off): within the interval the interval data will be marked as incomplete; within a day the old and the new intervals data will be marked as incomplete,

the data between the intervals will be marked as absent; into another day the new day data will be formed. In case the time is put backward: within the interval the interval data will be marked as incomplete; within a day the new interval data will be marked as incomplete, all the data of

the intervals run twice represents the sum of the first and the second runs; into another day the new day data will be formed, and the same day time will be

stored in profiles. While automatic summer switch from 2:00 to 3:00 on the last Sunday of the switch

month set, from 2:00 to 3:00 interval data will be marked as absent. While automatic winter time switch from 3:00 to 2:00 on the last Sunday of the switch

month set, additional hour interval data will be formed separately. Each profile can store interval

data of only one (the last one) additional hour. Additional hour interval data is changed (with data creation dating), if the meter was switched on the day of winter time switch. If the meter was switched off during the whole day of time switch the previous additional hour interval data is stored in the profiles.

4.6.12 Time correction and setting Time setting suggests setting of any time, date and day of week. It is reasonable to use

this instruction only before putting the meter into operation in case it was taken into another time zone, after repair or long-term storage, and at clock failure resulted from switched off power lithium element failure.

Time correction (30 s) may be accomplished fingertip only once a day (Cl. 5.2.6), or via digital interfaces (CL. 5.4.3). If the departure comprises more than 30 s. the correction should be accomplished during several days or time setting instruction should be used. The minus correction is accomplished by setting second readings to zero in case the current second value was not more than 29 s. The plus correction is accomplished by setting readings to 59 s. in case the current second value was 30 s. or more.

At low and high temperatures the clock readings departure may comprise up to 9 s/day. It is possible to set clock rate autocorrection in the meter. At the producing plant the

clock was calibrated at standard temperature. In case the clock readings departure takes place, it is possible to calculate and change clock rate calibration factor:

to calculate day clock readings departure for several days to within second deciles (for slow clock with - sign, for fast clock with + sign);

to read the meter calibration factor and chose the corresponding day clock readings departure from Table 4.6;

to put together the chosen and the calculated day clock readings departures considering signs;

to chose the corresponding calibration factor from Table 4.6 and log it into the meter according to the received summarized clock readings departure. Table 4.6

4.6.13 Access passwords (PSWzz, CRWzz) Programming and parameter reading access limit is realized with passwords. The

password, with which the access to programming was accomplished, is fixed in the programming log. The meter supports up to 4 passwords of up to 8 symbols length. Administrator (password #1) can change any password, the others only their own ones. Empty password (with no symbols) is considered inactive.

Only the administrator can change the configuration of the accessible for Users (passwords #2, #3, #4) programmable and readable parameter groups and configuration of the parameters output in the mode of reading data with no password.

ATTENTION! At triple incorrect password introduction the access to the meter is blocked till the end of a day.

4.6.14 Accumulated calculating machine channel data reset After calculating machine channels programming, it is recommended to set to zero the

accumulated data on: energy with progressive total of all the channels per tariff; energy accumulated during all the months of all the channels per tariff; energy accumulated during all the days of all the channels per tariff; maximum average powers for all the months of all the channels per tariff. Accumulated data reset is accomplished in manual mode (in case it is enabled). To set calculating machine channel data to zero it is necessary to: enable reset mode (to log the instruction via interface); place the meter in the programming mode press the button Access (the text

Access and countdown is displayed on LCD); press the button SCROLL (the text CLEAR and countdown is displayed on

LCD); press the button Access not later than in 3 seconds. The date and time of setting to zero are fixed in the corresponding register. Note each profile data is reset individually (Cl. 4.6.11). 4.6.15 Access password, record locking, response delay reset The meter allows changing access passwords to prohibit unauthorized programming and

reading. The meter allows prohibiting programming via any digital interface to reduce the

possibility of unauthorized programming.

The meter allows changing the time of delay via interface from 1 to 255 ms. The parameter serves for reducing the time of exchange and can be collated depending on the apparatus connected and PC software support. For instance, some EIA485 interface adaptors with automatic transmission direction switch require the response delay of more than 70 ms.

In critical situations when the access password is lost, the programming for all interfaces is prohibited and response delay time is less than accepted, setting of the following parameters is supported by default:

access password #1 777777; other passwords not set; programming via all the interfaces is enabled; response delay 200 ms. For value default setting it is necessary to: place the meter in the programming mode press the button Access (the text

Access and countdown is displayed o LCD); press the button SCROLL (the text CLEAR and countdown is displayed on

LCD); press the button Access not later than in 3 seconds. The date and time of value default setting is fixed in the corresponding register. 5 OPERATION PROCEDURE The meter reading is possible both in manual and automated modes. In the automated mode the complete information on energy consumption may be

obtained with PC via interfaces. Data exchange via interfaces is given in Cl. 5.4. In manual mode the data is displayed on LCD in the window of seven decimals with

decimal point and character multipliers width (k=103, M=106, G=109). The full list of output formats of measured, calculated and accumulated parameters is

given in Table 5.1 Table 5.1

5.1 Calculating machine channel data display on LCD

5.1.1 Register values display

Calculating machine channel energies are stored in registers of 19 decimal width with 10 mWh resolution (i.e. 5 decimals after the point for units of kWh measurement). Maximum accepted value of accumulated calculating machine channel energy comprises 401012 kWh, that cannot be exceeded even in case of meter operation at maximum load, with maximum accepted measuring transformers ratios during the whole service life. To meet GOST R 52320-2005 requirements to register for different modifications meters, different variants of register display on LCD are chosen (Table 3.3). As the meter accomplishes input end metering, the register display window automatically undents by the value proportional to power transformation ratio (Rp=RvRc). Register value on the left of the window is a number of window width overflows. Register value on the right of the window is a fraction of display least significant bit unit. The example of 57.7 V 5 A transformer connection meter LCD display window is given in Table 5.2 Table 5.2 Register and display window position
