<P>PROBLEM TO BE SOLVED: To provide an inspection system capable of easily and simply inspecting behavior of an electric leakage sensor for sensing electric leakage even if a common mode voltage changes in the power supply for a vehicle and the like. <P>SOLUTION: The power supply comprises a battery 10, a motor 15 driven by the battery, a power conversion means 20 disposed between the battery and the motor, a pseudoelectric leakage generating means 55 for causing an electric leakage state between the battery and a car body, and an electric leakage sensor 30 for sensing the pseudoelectric leakage. The inspection system for inspecting the behavior of the electric leakage sensor comprises a switching means 62 that connects/disconnects the power conversion means from the battery, and a switching sensing means 63 which senses switching of the switching means and outputs the sensing result to the pseudoelectric leakage generating means and the electric leakage sensor. If the switching sensing means senses switching of the switching means, the pseudoelectric leakage and sensing of electric leakage is re-tried. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
