GDYD-137D AC Hipot Test Set 7kVA.140kV for Boom Truck Testing
I.General information
GDYD series AC hipot test set is composed of manual control unit and AC gas testing transformer(HV unit) which output AC voltage smoothly. It is suitable for testing boom truck.
II.Features
Digital display meters mounted on the panel.
MonitoringHV side voltage, HV side current, LV side current and indicator of zero,power, working start,timing.
Over-current protection,zero-starting protection,sound, and light alarm.
With new type time relay,time rangeis wider (1S ~ 99H).
Using the latest current relay, more accurate and reliable.
Light weight, small size, easy to move.
