Abstract
A leakage current compensation system may be used in an appliance such as a cooking appliance or another device utilizing a sheathed electrical heating element, and may sense a leakage current in one or more phases of a multi-phase power circuit that supplies the appliance or other device using a current transformer and generate a compensating current in a different phase of the multi-phase power circuit to compensate for the leakage current and thereby reduce the likelihood of a false GFCI trip in the multi-phase power circuit.
