GDYD-137D 130kV 50mA 36kV 180mA AC Dielectric Test Sets
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 trucks.
II.Features
Digital display meters are 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.
