Trip Circuit Supervision Relay

Trip Circuit Supervision Relay - is an electronic circuit based relay which is used to monitor and supervise the integrity of Circuit breakers trip coil and other wiring circuits of low-voltage and medium-voltage network. Trip Circuit supervision relay is connected with a circuit breaker to monitor the trip circuit positions (Open or closed). Trip Circuit Supervision Relay generates a trip circuit failure alarm, either if the trip circuit supply is disconnected or if the trip circuit connection is changed to an open circuit. Trip circuit continuity is measured by supplying the supervision current of 0.7 mA to 1.5 mA and sensing the flow of current with two opto-couplers. The circuit breaker contact indicates the status of relay whether the circuit breaker is in open position or closed position. The front panel of Trip Circuit Supervision Relay comprises of single LED with dual colored to indicate the status of process. In a healthy condition, the Green LED flashes and the output relay reaches the pick-up condition. In the fault condition, the Red LED flashes and the output relay reaches the drop-off condition and operates after a delay of 500 ms.

The salient features of Trip Circuit Supervision Relay are:

Universal auxiliary voltage range with very low burden (i.e.) 24 V to 230 V AC/DC at less than 4 watts
Universal supervision voltage range (i.e.) 24 V to 230 V DC
Compact-in-size 48x96 mm
Fitted with flush-mounting
Continuous supervision of trip circuit in Pre-closed, Post-closed condition, and latched trip condition
Detects faults such as Auxiliary voltage loss and circuit breakage in supervised circuits
Indicates operational status by single LED with dual color
Relay has been type tested in accordance with IEC60255 standards
