Impulse Voltage Test System can produce a wide range of voltage and energy to simulate waveform such as lightning impulse, lightning chopped wave,switching impulse,to carry out impulse test for high voltage power equipment.When using steep device,it can make steep wave test for insulators(insulator string).
1. Spring pressure type for the connector, easy to plug when adjusting wave.
2. Unified connector is used for connecting rod of the main body, easy connection.
3. Optical fiber isolated ethernet port communication between the computer control system and the main body.
4. Full wave and chopped wave are electronic circuit,to adjust delaying ignition triggering.
5. Trigger mode of three-gaps ball discharge,to ensure the reliability of the trigger.
