A lot of vacuum circuit breakers (VCBs) have been installed for a period of high economic growth. Such VCBs are desired to be used until their application limit while maintenance cost should be reduced. Therefore, to realize the diagnostic technique which can be applicable even under the operating condition is important. In this study, partial discharges (PDs) occurred on the insulation material surface of a VCB were detected using an electromagnetic wave (EM) sensor. Characteristics of the detected EM waves were investigated. Based on the results, we made a prototype model with an analyzing program utilizing a LabVIEW.
