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. The injected current is sensed by two opto-couplers.
Auxiliary, signalling and tripping relays. RXMA RXMA RXMM RXMS RXSF RXME .
Suitable for tripping, blocking, interlocking, signalling etc.
Various ratings and contact configurations.
The trip circuit supervision relay. SPER 1BCis used for supervising impor- tant control circuits such as circuit-breaker and disconnector control circuits and signal- ling circuits in power electrical installations. Generally one supervision relay is needed per circuit to be supervised.
SPER series supervision relays are used for moni- toring important control circuits such as circuit breaker and disconnector control circuits, sig- nalling circuits, etc.
One contact circuit is monitored by one relay. The temperature monitoring relays CM- TCS monitor overtemperature, undertemperature, or temperatures between two threshold values. As soon as the temperature falls below or exceeds the threshold value the output relays change their positions according to the configured . Generally, one supervision relay is needed per circuit to be supervised. ABB trip circuit supervision relays are also available in COMBIFLEX design, please see products SPER 1Cand SPER 1C2.
Relay for man or backup circuit supervision.
ABB Substation Automation Products. LED does not glow and the output relay drops off. Relays with differing rated voltage for supervision circuit and auxiliary supply can be . Motor protection and control with sensor.
Three-phase current measurement.
Negative phase sequence current. The REF6is the most powerful, advanced and simplest feeder protection relay in its class, per- fectly offering time and instantaneous overcurrent, negative sequence overcurrent, phase discontinuity, breaker failure, thermal overloa and voltage mete-. Unit ready contact activation will be stored as an event.
When trip circuit becomes faulty, an event of trip circuit faulty will be recorded.
