1. Due to the large conducted current in the windings of large water-cooled generators, it varies from 20-150mA under test voltage. If there is no DC high-voltage generator with sufficient capacity, it is impossible to boost the voltage;

2. At present, the output current of domestic DC high-voltage testers is generally within 10mA, and high-voltage generators with an output current of 200mA are blank;

3. For general high-voltage electrical equipment, DC testing can detect insulation penetration defects, while for motors, it can detect local insulation defects (insulation at the end of the stator coil), which cannot be replaced by other tests;

4. To accurately measure the leakage current of water-cooled generator sets, the 60kV/200mA seriesWater cooled DC high-voltage generatorSpecially designed compensation circuits for various interference currents can eliminate the influence of stray currents and polarization potential interference from the water collection pipe during testing, and truly measure the current of the test sample;

ZGS-60kV/200mAWater cooled DC high-voltage generatorTechnical Specifications

For generators, conducting DC tests can sensitively and effectively detect stator winding end defects and gap defects. It has become a commonly used method in insulation testing of generator windings. Due to the large current conducted through the water collection pipe of large water-cooled generators, and depending on the water quality, the current generally ranges from 20 to 150mA under test voltage. Without a DC high-voltage generator with sufficient capacity, it will be impossible to increase the voltage. The ZGFS series leakage current tester for water-cooled generators is developed specifically for conducting leakage current and DC high voltage tests on generators, especially water-cooled generators. It is specially designed with compensation circuits for various interference currents, which can eliminate the influence of stray currents and polarization potential interference of the water collection pipe during testing, and accurately measure the leakage current of the water-cooled generator winding.
