"WebIn semiconductor devices, leakage is a quantum phenomenon where mobile charge carriers (electrons or holes) tunnel through an insulating region. Leakage increases exponentially as the thickness of the insulating region decreases. Tunneling leakage can also occur across semiconductor junctions between heavily doped P-type and N-type semiconductors. " - High earth leakage

High earth leakage

Webtransformer often leads to high earth leakage currents under normal operation. The effect becomes more pronounced as higher system voltages are introduced. This implies that the jump from low-to-medium voltage requires a rethinking regarding the design. Especially (but not exclusively) for underground mining, high earth leakage currents are not WebAny imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA. For example, taking a measurement on a 240 V ac circuit with all loads disconnected might result in a value of 0.02 A (20 mA) leakage.
