Voltage Indicator Used in Ring Main Unit

The voltage indicator is used together with insulator to indicate electriferous state of the voltage circuitry.

The continuous voltage detector GPXN9-C is used with indicator to indicate the electriferous state. The hole distance of the powercheck terminal is 14mm or 19mm.

Phase comparator GPXN-C is used with indicator to indicate the electriferous state of high voltage circuitry and check phase sequence of electrical equipment.

Power-check: phase comparator insert into the earthing or the other terminals of the high-voltage equipment.

Phase-check: phase comparator insert into the same phase powercheck terminal of two high-voltage equipment, if the LED light is bright, it shows that the testing phase having power supply.
