The leakage current clamp meter is widely used for insulation control of low voltage circuits as the supplementary method of the insulation resistance measurement. The control of leakage currents 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 (10) includes the capacitive leakage current (I0c) originating in the capacitance and the resistive leakage current (I0r) originating in the insulation resistance each related to the ground. 

• Supports measurement of the resistive leakage current (I0r) without voltage input.
