Abstract
A power supply system includes first and second power supply lines to respectively connect positive and negative electrode terminals of a load with a main power supply. First and second voltage detection lines are respectively connected to the first and second power supply lines via first and second resistances. First and second inspection power supplies respectively supply power and provide potential differences to the first and second voltage detection lines from the first and second power supply lines. Occurrence of a short circuit in one of the first and second voltage detection lines is recognized when corresponding one of the first and second inspection power supplies supplies power and a difference between a preset voltage and a voltage caused between the first and second voltage detection lines is a threshold value or more.
