Application
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.
