What is a capacitive leakage current?
The capacitive leakage current described in Section 2 is a reactive current (without loss). However, if a fault such as a defective insulation causes a live line to come into contact with a grounded person (see Figure 3), an additional current flows to ground. This unwanted current causes losses and is referred to as residual current.
