Water Cooled Generator DC Withstand Voltage Tester
DC withstand voltage test for the general high-voltage electrical equipment, can find the insulation penetration defects, and for the motor, it can be unique to find its local insulation defects (stator line coil end insulation), which cannot be replaced by other tests. The conduction current of the water cooled generator winding is very large, it should be about 20-150mA at the test voltage. Voltage can not be boosted without a sufficient capacity DC high voltage generator. For this reason, we design and manufacture the water cooled generator DC withstand voltage tester，it is specially designed for the leakage current and DC withstand voltage test of water cooled generator.

Purpose and test method of AC withstand voltage test for transformer
The AC withstand voltage test is a destructive test in the insulation test. It can only be carried out after other non-destructive tests (such as insulation resistance and absorption ratio test, DC leakage test, dielectric loss tangent and insulation oil test) are passed. After this test is passed, the transformer can be put into operation.
