GDYD series AC Hipot Test Set is composed of manual control unit and AC oil testing transformer(HV unit) which output AC voltage smoothly. Meanwhile, it has many monitoring and protection functions.
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 rang is wider (1S ~ 99H).
Using the latest current relay, more accurate and reliable.
Light weight, small size, easy to move.
