300KV High Voltage Testing Equipment

DC High Voltage Generator

Widely used in electricity power supply companies, power transmission and transformation

engineering company and large industrial enterprises for preventive test

and scientific research institutes for dc high voltage power supply

Features & Technical Index

1) adopts high frequency PWM technology to make closed adjustment with high voltage stability,

small ripple factor and fast reliable protection circuit.

2) Can endure direct discharge to ground by devices of large capacitance

3) small size and light weight, convenient for field use

4) Full range of linear smoothly adjusted voltage, with voltage regulation accuracy smaller than 0.1%;

voltage measurement accuracy is 0.5%, resolution 0.1kv; Current measurement accuracy is 0.5%,

the minimum resolution: control box 1µA, shock resistance current 0.1µA.

5) AC 220 V power supply(AC220V±10%, 50 hz±1%), ripple factor less than 0.5%

6) High voltage multiplier uses Dupont materials for full solid encapsulation, overcoming the inconvenience

brought by the air and oil filled equipment. Broad base and outer cylinder of light quality makes it stand

steadily and more convenient for maintenance

7) 75% MOA voltage switch button, simple and convenient testing arrester

8) Over-voltage setting function displays the over-voltage value during regulation process; perfect protection

against discharge of over-voltage, over-current and short circuit

9) Perfect break line and non-zero potential start protection function protects the operator and samples at any time
