Abstract
A failure inspection system includes a main circuit section, an electrically conductive member, capacitors, a signal generating section, a measurement section and a judgement section. The signal generating section generates a high-frequency AC signal and a low-frequency AC signal. The judgement section determines whether either one of two types of failure has occurred based on the voltage or the current of the high-frequency AC signal. If it is determined that a failure is occurring, the judgment section specifies that which of failures, a leakage current failure or a short-circuit failure, the failure that has occurred is, based on a measurement value of the low-frequency AC signal derived from the measurement section.
