TAG-8500 Power-off Phase Sequence Meter

Used for phase identification on de-energized transmission lines, switchgear, and live displays. Ensures consistent phase naming with the main grid and solves future grid-connection issues.

Important: Only for use on de-energized cable cores. Always verify power is off before testing.
