Abstract
A method and a system for cancelling stray currents in a marine electrical supply system, which system comprises a protective earth circuit connecting a vessel to ground when a source of power is connected to the vessel is described. The method involves the steps of monitoring the current in the protective earth circuit using a current sensor; determining if a stray current is detected by the current sensor, and, if a stray current is detected, counteracting the stray current in the protective earth circuit to reduce the stray current to a value at or near zero current.
