Abstract
A grid relay state detector includes an AC (Alternating Current) signal source capacitively coupled to at least one grid relay. It further includes a current sensor that detects an amount of AC current flowing through the at least one grid relay. A state of the at least one grid relay is determined based at least in part on the detected amount of AC current.
