    8.13.2 Behaviour of a system with leakage If the voltage measured between one of the two poles and ground does not tend to 0V and stabilizes on a value, there is a ground leakage from the PV generator. Example: When the measurement is made between positive pole and ground, a voltage of 200V is measured.
