PHASE INDICATOR

Phase indicator is a measuring instrument used to verify phase rotation (R, S, T) and detect missing phase in three-phase power systems. It is an essential tool for electrical work and maintenance.
It is used to confirm the rotation direction of motors and to verify the wiring of three-phase circuits, helping to prevent reverse rotation due to incorrect wiring and equipment troubles. There are contact and non-contact types, and it is important to select the appropriate one based on the measurement method and operating environment.
