A new function is available for Earth Leakage relays Type B and Type A-F that allows to constantly monitor the efficiency of the circuit breaker Trip circuit when is made of a shunt release coil.

The alarm contact (TCS Alarm) will be as positive safety (normally energized) and will be released after the programmed activation time delay in the following situations:

- Lack of device auxiliary supply (no delay, device off)

- When ELR is operating in measuring mode, in case of shunt release coil connection fault or in case of lack of the relevant auxiliary supply

- When ELR is operating in tripping mode, if the contacts (COM, NO) of the Trip Relay are not closed.

When normal operating conditions are restored, the Alarm Contact will be energized again after a programmable release time delay (or in manual mode with Memory setting).

Check out the Ordering Code for this new function in the Data Sheet of each type.

Multifunction network analyzers with miniature split-core CTs

The kit consists of a multifunction network analyzer of NANO or QUBO series with 3 miniature split-core CTs. It is suitable for use in three-phase with three or four wires electrical systems, even with unbalanced loads and distorted waveforms, for the acquisition of all the main measurements. The small size of the miniature CTs allows an installation even in places with a reduced access, making this system suitable for retrotting in existing installations, but also an excellent solution for monitoring electrical networks in new installations.

Multifunction network analyzer with 3 Rogowski coils

Q96R3H - The multifunction network analyzer is supplied with 3 Rogowski coils, the analyzer input does not require external integrators. It is suitable for use in 3-phase three-wires or four-wires  systems, even with unba- lanced loads and distorted waveforms. It permits to get all the main  measurements, including power and energy both generated and consumed. The connection is simplified with RJ45 connectors. The system is suitable for retrofitting in existing installations and for laboratory use, but also an excellent solution for monitoring electrical networks in new installations.
