ABSTRACT:
A detection system for detecting unintentional impedances between the power conductors and a first node of either a power conversion circuit or a load, the first node typically being an earth ground. The circuit has power level lines utilizing a wye-connected line filter network which has equal impedance values for each leg of the line filter and which defines a first node at the common connection thereof. A different impedance network is also connected in wye-fashion to the power level lines and defines a second node at the common connection thereof. Each impedance leg of the impedance network is also equal in impedance value whereby the second node normally has the same potential as the first node. The potential difference between the first and second nodes is frequency compensated to produce a system output signal indicative of a predetermined value of current in unintentional impedance between any of the power conductors and the first node.
