50hz 4in1 leakage pdf

Apr 12, 2019They generate current leakages at the mains frequency, 50Hz, and at higher frequencies under normal operating conditions. As soon as they are connected to the electrical power supply they generate a leakage current point. During an insulation fault, the leakage current might not be sinusoidal, but rather pulsating, for example.
