Abstract
A control method of a ground fault detection apparatus for detecting a decrease in an insulation resistance of a system including a battery that is not grounded and a Y capacitor includes an insulation-resistance-decrease detection step of controlling a switching portion to measure a charging voltage of the first capacitor and to perform a detection of a decrease in the insulation resistance based on the measured charging voltage of the first capacitor, wherein the insulation-resistance-decrease detection step is initiated when a first period has elapsed from a startup process for starting up the ground fault detection apparatus is finished.
