Abstract
A power circuit configured to generate and distribute DC electrical power, the power circuit includes a photovoltaic (PV) system that includes an array of PV modules electrically coupled to a combiner box, and an inverter positioned to receive DC electrical power from the array of PV modules and output AC electrical power. The PV system also includes a signal generator coupled to a first portion of the PV system, and a signal detector coupled to a second portion of the PV system, the signal detector configured to detect secondary signals generated at a loose connection of an electrical joint in the PV system, wherein the secondary signals result from a signal generated by the signal generator.
