Abstract

The application of circuit breaker in switchgear system is a common method to use as a protection system. Circuit Breaker Profiler is a circuit to be use to study the trip coil characteristic of circuit breaker. In this project, it is focused on 33kV Circuit Breaker and Circuit Breaker Profiler will be use to study several case study based on circuit breaker mechanism timing test. Based on the test held, the result of the test will be use to build a trip coil profile signature; this technique known as fingerprinting technique. Timing test will validate that a circuit breaker of the overall operation within the set limits, but it will be indicate that monitoring the current flow via the trip coil of the circuit breaker, can allocate a very dominant tool in analysing the preparedness of a circuit breaker to trip. The result of the testing specimen of DC current of circuit breaker against time will be interpreted the average or mean graph of time (millisecond) and DC Current (A) also will be developed in order to determine appropriate Trip Coil Current Profile. Upon the completion of this project, appropriate Trip Coil Current Profile and the assessment of switchgear will be known.
