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.
