Purpose of medical equipment leakage current test

To avoid insulation breakdown caused by leakage current. Leakage current refers to electrical appliances in normal operation, its fire wire and zero line between the extremely small current, equivalent to the general electrical appliances like static electricity. The purpose of measuring the leakage current of medical equipment is to be afraid of the cable, winding coil and other electrical components facilities by the influence of the environment or insulating tools used for a long time, resulting in insufficient insulation strength, to avoid insulation breakdown caused by leakage. Medical equipment winding leakage current detection, applicable to high-voltage motors after overhaul, low-voltage motors do not have to do leakage current test, as long as the resistance to ground up to 0.5 megohm can be used.
