DC high voltage generator how to choose it?

DC high-voltage generators are widely used in power testing departments of power companies, mining, metallurgy, and iron and steel companies. Conduct high-voltage DC high-voltage tests on zinc oxide arresters, power cables, transformers, generators and other high-voltage electrical equipment. It is an important equipment for high-pressure test professional. The following principles should be followed for its selection and use:

When selecting

1.1, the product should pass the type test

1.2. The product should pass the network assessment organized by the relevant provincial Electric Power Testing and Research Institute, and the evaluation results of provinces that can not participate in other provinces are not evaluated.

1.3. The product should have enterprise standards, and the enterprise standard must not be lower than the industry standard.

1.4. It should be a professional DC high-voltage power supply manufacturer with complete process equipment, inspection equipment and corresponding engineering technicians and production personnel.
