What causes leakage in a power line filter?
Residual current devices or leakage current breakers are found more and more in order to interrupt the supply if high leakage current is detected. Power line filters, or EMC filters, contribute to the overall leakage current of equipment with their capacitors against earth.
What causes a high leakage current in an EMC filter?
In particular, a change in motor speed can have a major influence on the resulting leakage current. For instance, leakage currents can become significantly larger if the inverter’s switching frequency is a multiple of the EMC filter’s resonant frequency. This puts the filter into oscillation and can generate high leakage currents.
Where does the leakage current in a circuit come from?
Leakage current most commonly flows in the insulation surrounding conductors and in the filters protecting electronic equipment around the home or office. So what’s the problem? On circuits protected by GFCIs (Ground Fault Current Interrupters), leakage current can cause unnecessary and intermittent tripping.
What is the line to ground leakage current?
What I am understanding here is that since in first one EACH LINE TO GROUND LEAKAGE CURRENT IS 0.4 mA it will sum up to 0.8mA for both. I am an Electronics person and Electrical bounces a little above my head. Kindly help. Figure 1. A mains filter. Notice the two Y capacitors. Source: Elliot Sound Systems.
