Abstract

To identify the fault types of high-voltage circuit breaker accurately and reliably

a fault diagnosis methodfor high voltage circuit breaker is formed. In this paper

the reclosing coil current of HV circuit breaker under differ-ent conditions is analyzed

in order to extract time and current as characteristic parameters to form training set. Com-bining random forest algorithm（RF）with training set

random forest classifier is established to distinguish faulttypes of high voltage circuit breakers efficiently. Experiments show that the algorithm can accurately distinguish thefault of high voltage circuit breaker

which greatly improves the utilization rate and efficiency of HV circuit breaker.
