DXN8D INDOOR HV CHARGED DISPLAY DEVICES (VPIS) SERIES HX2-2 TYPE PHASE COMPARATOR (PC)

Technical parameter of phase comparator

The internal adopts lower power consumption Neon bulb light emitting element, when input voltage is over 60V, the indicating lamp of comparator lights up

When phase are the same, the indicating lamp will not light up

When pahses are different, the indicating lamp will light up

Two ends of comparator adopts 4mm standard banana plug, the length of testing cable: 2m

Dimension of phase comparator

Using method of phase comparator

Before phase  comparison, operator should make sure all wirings are correct within HV switchgear, namely the sequenves of cables between voltage sensor and voltage indicator are right. When two HV powers are supplying normally, operator should do the following steps after making sure all voltage indicator are normally working: Insert one plug of the comparator end into L1 phase testing end on the voltage indicator of working power switchgear, then insert the other plug of the comparator end into L1,L2,L3 phase testing end separately on the voltage indicator panels of pending power supply switchgear, to observe the indicator light conditions of comparator.
