Product Description

Plastic box 50kV AC DC Hipot Test Set for Transformer

I. General information

GDYD series AC/DC hipot testing is the effective and direct way to test insulation strength for electrical equipments,apparatus or machines. It checks dangerous flaws which assure electrical equipment continuous working.
Typical applications include testing of transformers, switchgear, cables, capacitors, aerial motors platforms, hot sticks bucket bricks, vacuum bottles and other related equipment like vacuum interrupters, blankets, ropes, gloves, hydraulics hose, instruments transformers generators.


II. Features

1. Digital display meters mounted on the panel.
2. Monitoring HV side voltage, HV side current, LV side current and indicator of zero, power, working start, timing.
3. Over-current protection, zero-starting protection, sound and light alarm.
4. With new type time relay, time range is more wider (1S ~ 99H).
5. Using the latest current relay, more accurate and reliable.
6. Light weight, small size, easy to move.
