General introduction

AC hipot testing is the effective and direct way to test insulation strength for electric equipment. It checks dangerous flaws and make sure electric equipment continuous working. It typically used to test insulation strength for all kinds of electrical equipment, components like capacitors, insulation materials.

The controller should be equipped with AC/DC HV source to boost. There are three types of testing transformers for optional:

1. Oil-immersed: large capacity, cheap, convenient maintenance, mainstream products.

2. Dry type: light weight, light volume, can run backward, price expensive.

3. Gas inflatable type: interrupter resistance, and light weight.

4. Series type high voltage testing transformer: small volume, low voltage, light weight, easy to transport and install.

General Information:

EPTC-M Series AC/DC Hipot Test Set is suitable for hipot dielectric withstand voltage testing on various power electric products, units, insulating materials. The controller should be equipped with AC/DC HV source to boost. There are three types of testing transformers for optional.


- Manual controlling.
