According to the different types of leakage current, the application of residual current protection is introduced in detail, and the corresponding leakage protection is analyzed on the basis of the four different charging modes of charging pile.
The leak rate Q L defined as a measure of leakiness is normally specified in the unit of measure mbar · l/s. With the assistance of the status equation (1.7) one can calculate Q L when giving the temperature T and the type of gas M, registering this quantitatively as mass flow, e.g. in the g/s unit of measure.
