Abstract
The present disclosure pertains to detection of abnormal, risky, or aberrant conditions in a power distribution network and to corresponding trip signals being used to trip open devices such as reclosers upstream of where the abnormal condition is detected. Detection of open phase on a distribution circuit prevents severed conductors from causing a ground fault, therefore avoiding the possibility of fire and dangerous conditions. The voltage unbalance may be measured using an end of line relay that includes an electrical sensor or relay, a tripping mechanism, and a signal transmitter.
