Zusammenfassung:	PURPOSE:To increase the safety of operations and to enable the sure detection of a phase in a short time, by detecting the phase through comparison of current values generated by the phase difference of the electrostatic induction voltage of each phase of the main circuit. CONSTITUTION:After the sizes of retaining rods 13 and 14 are fixed in safe lengths, detectors 11 and 12 are fitted to the respective ends of the rods, and they are arranged and retained manually below the main circuit whose phase is to be detected, respectively. In addition, the detectors 11 and 12 detect an electrostatic induction voltage from each phase of a line switch 31, and microvoltages thus detected are led to an ammeter 17 via shield cables 15 and 16. The ammeter 17 measures a current generated by the phase difference of the microvoltages which are led therein.
