<p>A system (20, 30, 40, 50) and method for canceling a leakage current is provided that uses line voltages (L1, L2) that are out of phase with each other to produce a counter leakage potential that cancels leakage current. In one embodiment of the invention, the actual potential of the phases is measured (42, 52, 54) and used to determine the counter potential that is to be applied to the line voltage (L1 or L2) that is generating the leakage current. The counter potential is applied to the appropriate line voltage by way of a transistor circuit (Q1, Q2). The transistor circuit (Q1, Q2) is controlled through standard electronic circuitry (28), or by way of a microprocessor device (32).</p> |
