PHASE SEQUENCE INDICATOR
Phase sequence indicator is a must for checking new electrical connections, installation and maintenance. It is useful in wiring of switchboards, when 3 phase watt meters and power factor meters are connected. In wiring 3 phase AC motors rotation can be checked and corrected if need be, by checking the sequence.
The instrument is of rotating disc type. When correctly connected to 3 phases R, Y and B the Black disc with white arrow rotates clockwise indicating that the phase sequence is correct. If the rotation is anti-clockwise one of the phases should be reversed.
