Digital Ior Leakage Current Clamp Tester
MCL-400IR+
-
MULTI MEASURING INSTRUMENTS Co., Ltd.
・About Ior Leakage CurrentRecently, the leakage current clamp meter is widely used for insulation control of low voltage circuit as the supplementary method of the insulation resistance measurement. The control of leakage current has the advantages to enable the prediction of insulation condition in the electrical power line without having to shut off the power. The leakage current (Io) includes the capacitive leakage current (Ioc)originated in the capacitance and the resistive leakage current (Ior) originated in the insulation resistance each related to the ground. It is considered that the measurement of resistive leakage current (Ior) is the very useful and effective method for the insulation control of low voltage circuit. However, it was difficult to measure the resistive leakage current (Ior)with traditional leakage current clamp meter. MCL-400IR new digital clamp tester enabled the measurements of the resistive leakage current (Ior)without voltage input(phase detection).
