ABSTRACT:
There is provided a state detecting method adopted to an insulation resistance detector including the steps of: calculating a difference between the output of the filter when a pulse signal having a first pulse width is applied to the series circuit, and the output of the filter when a pulse signal having a second pulse width shorter than the first pulse width is applied to the series circuit; and detecting the state of the insulation resistance detector based on the calculated difference.
