Product Description
Features
- Low supervision current
- Continuous monitoring of complete trip circuit independent of the circuit breaker position
- Detects faults in the supervised circuits such as loss of voltage, circuit breakage
- Sensing by electronic circuit
APPLICATION
Trip Circuit Supervision Relay (TCSR) is used for monitoring healthiness of the circuit breaker (CB) trip circuit, CB trip coil and CB power supply.
PRINCIPLE OF OPERATION
TCSR monitors the healthiness of the trip circuit of breaker. Basically the circuit drives a small current through the breaker trip coil and monitor it continuously. If there is any failure in the trip circuit or trip coil circuit, the relay will sense and operate it's output contacts. About 400ms delay is introduced to prevent false indication during circuit breaker operation. A test button is provided to test the relay contacts for trip and alarm in healthy condition only.
The facility for monitoring two trip coils with independent power supply is provided in one enclosure.
