DC Hipot Test Systems 5mA 400kv DC Hipot Tester Impulse High Voltage Generator
Product introduction
DC hipot tester is widely applied in the DC HV tests carried out for the zinc oxide lightening arrester, magnetic blow-out arrester, power cable, generator, transformer, circuit breaker, etc.
60/80/100/120/200/250/300/400/500KV,
2/3/5/10mA can be customized.
Features
1. High reliabiliy: high frequency voltage multi-doubler reticfier, simple circuit, high overload capability, rare fault, without maintenance.
2. Small volume: one person can carry the largest HVDC generator (200kV/2mA). Its volume is only 1/(2~5) as the volume of the same kind of equipment made in Japan. It reaches the advanced level in the world.
3. Perfect seal by metal housing, high mechnical stength. Irs performence will not be influenced by viberation, moisture, dust and meterological condition.
4. Safe, convenience in operation, metal housing grounded. built-in HV terminals.
5. There is no high voltage and low voltage connecter outside, easy connection.
6. Good auto protection function. It can nor be switched on if the HV output knob is not at zero position. Poeration is simplw. It will not cause maloperation and automatically switch off in over voltage and overcurrent case. There is dampong resistor indide.It is not necessary to connect damping resistor outside.
7. Excellent accuracy: The leakage current at HV side is meadured by digital meter accuracy: 1uA, range switch is not required, disvharge withstand current measurement function is available at low voltage side, It use precise resistor with good stability to measure high voltage.
