Supervision relays

Relays for critical and safety applications in substations and HV power systems


Arteche trip circuit supervision relays monitor trip coil circuit in open/close states and during circuit breaker operation. TCS relays are used for DC supervision via LOR trip coil, generating an alarm and avoiding open/close commands under faulty conditions or when breaker tripping mechanism is not ready to operate.

With references for single pole and 3 pole and a wide range of voltages, VDF / VDJ trip circuit supervision relays performs monitoring functions over circuits, fuses, and MCBs involved in the control power supply circuit of switchgears and other critical control circuits.

Suited for demanding applications in substation environments, RUT trip supply supervision relays generate an alarm and avoid open/close commands if the power supply circuit of a circuit breaker is under faulty conditions.
