		abstract={Power breaker is a circuit breaker equipment, which has a function that is used to disconnect an electric circuit in a loaded or unloaded state. In this case, the circuit breaker cannot operate normally, the purpose of not being able to operate normally is that the mechanical system of the circuit breaker, namely the under voltage tripping coil, is imperfect when locking so that the breaker cannot operate. Therefore, the calculation of the breaker capacity is carried out, the calculation of the insulation resistance and the calculation of the simultaneous contact of the circuit breaker. The results of measuring the capacity of the 6 kV circuit breaker are still in accordance with the standard rating of the power breaker capacity, which is 23.90 kA, while the measurement of the insulation resistance of the 6 kV circuit breaker is in good condition because the value of the insulation resistance is in accordance with the standard SE equipment maintenance book. . 032/PST/1984 is larger than 1 M?. From the measurement results on the simultaneous operation of the circuit breaker, the difference in the working time of the circuit breaker in the open condition is 10.1 ms and the closed condition is 10.3 ms where the value exceeds the predetermined standard, which is < 10 ms, causing the system to work on the breaker. power has decreased, causing the circuit breaker to not operate normally.}
