Abstract :
Permanent disturbance is a disorder that can not go away by itself, temporary disturbance is a relatively short disturbance, usually caused by lightning strikes, rain, angina, or friction-friction trees near the network. Circuit Breaker Outgoing functioning as an electric circuit breaker and fast-switching under normal circumstances or in disturbances, this cubicle is also known as the cubicle PMT (Power Breaker) is equipped with a protective relay and circuit breaker. This cubicle can also be installed as a limiting device. This cubicle can also be installed as a limiting device. After calculating the impedance of short circuit 1 phase, 2 phase, and 3 phase, then re-setting the CBO with the current relay setting and the correct ground disturbance is the current through the relay = 0.06 A, the current acting on the OCR relay = 0.12 A, and the current works on the OCR moment = 0.6 A. The correct ground fault relay setting is the current working on the relay GFR = 0.15 A, and the current working on the moment GFR = 0.75 A, the TMS working on the OCR is 0.9s and the TMS working on the GFR is 0.8s
