Earth Fault - Leakage Current

Contents

Earth-fault leakage current for marine IT (isolated) distribution - the basis for alarm-setting on insulation-monitoring devices.

Formula

$$ I_L = \frac{U_n}{\sqrt 3 X_C}, \quad X_C = \frac{1}{2\pi f C} $$

Symbol	Meaning	Unit	Source
$U_n$	Nominal voltage	V	switchboard rating
$C$	Network capacitance	µF	cable + equipment
