Abstract
The present invention relates to a system and a method of measuring insulation resistance, which separate a region in which insulation resistance is positioned by installing a device performing a function equivalent to a relay on a path in which insulation resistance of an electric vehicle is measured and measure an insulation resistance value for each region, to recognize a region in which insulation resistance breakdown occurs when breakdown of insulation resistance occurs.
