Abstract
In this paper
a tripping of circuit breaker in capacitor bank is taken as an example to analyze the reason for the tripping one by one. The process on finding the fault is described in detail and it is confirmed finally that the tripping of the circuit breaker is due to dielectric reduction of control circuit and
at the same time
the related preventive measures and suggestion on such fault is raised for the substation operators as reference.
