Trip circuit supervision relay ABB. The supervision relay TCS is designed for the supervision of trip circuits and other important control and monitoring circuits. Block diagram of the relay is shown in Fig. 1. The supervision function is based on a low-level (~ 3 mA) current injection principle. The injected current is sensed by two opto-couplers. The supervision function in three steady states of circuit breaker-trip circuit can be
The trip circuit supervision relay SPER 1C1 is used for supervising important control circuits, such as, circuit-breaker and disconnector control circuits and signalling circuits in power.
Multifunction protection with synchronization – SIPROTEC 7SJ64.
The SIPROTEC 7SJ64 can be used as a protective control and monitoring relay for distribution feeders and transmission lines of any voltage in networks that are earthed (grounded), low.
