Abstract:
In an embodiment, a missing utility ground detection circuit includes a pair of balanced resistors each connected to receive utility voltage from a different one of a pair of utility power lines, the balanced resistors being connected together at a summing node to be capable of summing the voltages from the pair of utility power lines. It includes an unbalance resistor connected to shunt voltage from one of the utility power lines. It has a summing amplifier with an input coupled to the summing node and to a reference voltage, and an input coupled to a second reference voltage. It has an averaging circuit connected at the output of the summing amplifier. A comparator is provided having an input connected to the averaging circuit an input connected to a threshold voltage.

Claim (Index 27):
A method for detecting a missing utility ground in utility voltage inputs, the method comprising:\n a) unbalancing one of the utility voltage inputs; b) sensing and summing the unbalanced one of the utility voltage inputs and an other of the utility voltage inputs; c) comparing the summed voltages to a reference threshold voltage to provide a compared output; d) averaging the compared output to provide an averaged output; and e) comparing the averaged output to a fault threshold voltage to provide a ground fault signal.
