ERC48 - ERC72 - ERC96 - ERC144 (90° interchangeable scale plate)

ERCL48 - ERCL72 - ERCL96 - ERCL144 (240° interchangeable scale plate)

The main characteristic of these instruments is their low current consumption, in circuits where high internalconsumption and drop in voltage can bring about measuring errors. The low consumption means that theseinstruments can also be used with converters, tacho generators or thermocouples. Up to 60A they can beprovided with an incorporated shunt for direct connection, above 60A use a separate shunt.

ELECTRONIC SYNCHRONOSCOPES

ERSI96These instruments are intended for measuring phase difference ∆ϕ between a bus-bar and a generator.Theyare provided with a synchronising check relay which enables switch-on of synchronisation when the setparameters are reached. These instruments are equipped with a circular display of phase angle whichconsists of 18 led’s.Momentary phase difference is displayed by led. Within synchronisation range (∆ϕ=0°between -15°el and +15°el) resolution is increased to 5°el. If difference of frequency between input voltagesexceeds 3Hz, three leds above FAST (fgen > frete) or SLOW (fgen < frete) inscription are alternately illuminated.A green SYNC. LED is illuminated when synchronisation conditions are made.A red ∆U led is illuminated when difference between voltages is above the set value or when the bus-barvoltage is lower then 80% of nominal value Un. In these instruments comparison of the input voltage ofgenerator Ugen and net Unet method is used ,through and A/D converter of the microprocessor.The inputvoltages are galvanically insulated by a transformer and a microprocessor controls all the operations of thesynchronoscope verifying the values of the input voltages coming from the A/D converter, determining thedifference of phase (∆ϕ) between generator and net. The synchronoscopes are provided with threepotentiometers for settting conditions of a synchronisation relay switch-on at the instrument rear side: forsetting permitted phase difference ∆ϕ, for setting permitted voltage difference ∆U, for a delay ofsynchronisation relay switch-on (DELAY). When phase difference and voltage difference between a generatorand bus-bar for time of delay of synchronisation check relay are within the set limits, the synchronisationcheck relay is switched on for approx 150ms. In that time the SYNC. Led is illuminated as well.INPUT VOLTAGE TECHNICAL DATA- Nominal voltage Un: 57, 100, 230, 400 V (to be specified when ordering)- Voltage range: Un +/-20%- Frequency range: 45/65 Hz- Burden (bus-bar):

By adopting a single instrument with an interchangeable scale and multi-voltage converter it is possible to obtain all the capacities shown on thetable below. It is sufficient to select the input voltage on the accessory and to insert the scale corresponding to the current transformer used.

If for example there is a need for a mono-phase 380V Wattmeter (Varmeter) with a C.T. ratio of 300/5A; the corresponding scale to insert into theinstrument has a 120KW (KVar) scale.

This function only applies if the input voltage is direct and not by means of a V.T. in which case calibration in the factory is preferable. If insteadit is necessary to take advantage of the multi-scale function, even if the entry voltage derives from a V.T., eg: 1500/100V, always bearing in mind amono-phase wattmeter, it is necessary to seek the voltage constant and therefore 1500:100=15.

In order to obtain the scale value to introduce into the indicating instrument, it is necessary to multiply the number found (15) by the value of the scaleon the table corresponding to C.T. 300/5A, which is 30KW (KVar)

Therefore 15 x 30KW (KVar) = 450KW (KVar)

In order to achieve the above, the various converters have been calibrated as follows:

For the Active Power:100V, 5A=500W 230V, 5A=1000W 400V, 5A=2000W in the single phase system

There is, pratically an unlimited variety of applications regarding electronic regulators.They are used for regulating and checking all those parameters which can be measured by an electrical instrument, both directly and by meansof a converter.These instruments offer a wide range of uses when there is a need for analogue signals, controls, automatic adjustments, protection, automaticprocess checks, etc.They have two adjustment channels which can be used one at a time or together and each channel has a potentiometer and a graduation in %of the scale (the scale value on the instrument corresponds to 100% on the graduated disc) and this adjustment can be carried out along theentire length of the scale.The diodes on the scale indicate whether the reading has been carried out inside or outside the limits of the scale limits.These instruments also have two timing circuits, one per channel, which make it possible to delay the exit signal when the user does not want

the pick-up currents to be indicated.The timer immediately returns to zero and, should the indicator oscillate, these various times are not totalled together.When the timing of the signal is not necessary it is sufficient to place the potentiometer on point 0 for the instrument to immediately operate.

SINGLE PHASE INSULATION INDICATORS

ERCC96MIThese instruments are used to measure continuously, with power applied, the insulation value respect to theearth of single phase lines with insulated neutral; or the insulation respect to the mass of the positive andnegative of direct current lines. The indicators ERCC96MI are provided with a separate accessory transducer(1RAMI) on which the power circuit is included.TECHNICAL DATAERCC96MI 1RAMIsee page 134 - Power supply: 100V AC ±10%

- Measurement input voltage: max 500VAC/DC- Operating frequency: 45 ÷ 65 Hz- Burden: 1,5 - 2 VA- Operating temperature: -10°C ÷ +55 °C

- Storage temperature: -40°C ÷ +70 °C- Overload: 1,2 Vn
