Voltage detectors are used to check whether an electric circuit or wire is energized (voltage is applied) by contacting the detector tip to a target. Phase detectors are used to check the phase detection, open phase, and phase sequence (RST sequence) of a three-phase AC motor or power supply, being clipped to the conductive part of the RST.
