Refine On (Hebei) Electric Power Technology Co., Ltd. is one of the leading manufacturers and suppliers of dc high voltage generator in China. If you're going to wholesale durable dc high voltage generator, welcome to get quotation from our factory. All customized products are with high quality and competitive price.
Application Scenarios
The DC High Voltage Generator performs insulation performance tests after equipment is shipped, accepted, periodically tested, and after major overhauls to check its quality. The principle is to simulate overvoltages that the equipment may encounter during operation, expose potential hazards in advance, and then carry out targeted treatment to prevent sudden power outages or more dangerous accidents during normal operation.

FAQ
Q: What does the parameter 120kV/5mA mean on a DC High Voltage Generator?
A: 120 represents the rated output voltage, with a maximum output of 120kV. 5mA represents the rated output current; when the equipment outputs 120kV high voltage, it can continuously provide a maximum current of 5mA.
Q: What parameters of DC high voltage generator should be used for a 17kV zinc oxide surge arrester?
A: 60kV~80kV is acceptable. Generally, the voltage should be 3-5 times the rated voltage of the equipment.
Q: When using a DC high voltage generator for cable testing, why is it recommended to use a current of 5mA or higher?
A: Cable withstand voltage depends on cable length and voltage rating; using a higher current will allow for faster testing.
