Abstract
Methods and systems for a hot circuit detector/indicator that continuously monitors a three-phase network and has visual indications for phase sequence, phase presence, and phase loss. The hot circuit indicator is a compact unit that, in a preferred embodiment, includes separate light emitting diode indicators for each phase and LEDs to indicate clockwise and counter-clockwise phase sequence. The hot circuit detector/indicator also includes a relay that can be a normally open or normally closed. The hot circuit indicator can be panel mounted or integrated into a connector supplying multi-phase voltage to a load. The multi-phase voltage to be monitored can be in a range between 12 vac and 38 kVac.
