method to evaluate the condition of CB’s contact. This research aims to predict the correlation between the various levels of contact degradation and characteristics of dynamic resistance waveform. Five diagnosis parameters are extracted rom DRM curve...

Circuit Breakers (CBs) are critical components in power system for reliability and protection. To assure their accurate performance, a comprehensive condition assessment is of an imminent importance. Based on dynamic resistance measurement (DRM...

technique

for assessing the condition of CBs main and arc contacts. Principal

component analysis (PCA) is used to provide the most valuable

information lidded in dynamic resistance signal. Experimental

data are collected through...
