Application: 
The field of applications is mainly the industrial test facility, university lab and country HV research centers. The system can be used to generate impulse voltages simulating lightning strokes and switching surges.This Impulse voltage generator suitable for lightning impulse full wave, chopping wave, switching impulse test, inspect equipment’s impulse insulation level. The system can also be used for insulator’s impulse flashover test and insulator impulse characteristic research under nonuniform pollution.

Question 1:
Can the impulse generator auto switching the polarity? How long will it take for switching?
Answer: Surely, the impulse generator can automatic switching the polarity, the silicon stack is fixed on the charging device, User can change switching the silicon stack from remote control system (PLC based), and it's takes around 10second to switching. 
Question 2:
How the impulse generator packing?
Answer: For the impulse generator <=300kV, we will pack it after installation & commissioning. The impulse generator main body is packed vertically in a seperately wooden case, in this way, when system arrive user plant, user can open and connect system easily. The charging device, impulse voltage divider and impulse control system / Chopping gaps will be packed in sperate wooden case. 
Question 3:
If the impulse generator CE certificated?
Answer: Yes, all of our Impulse Voltage Generator Control and Measuring System are CE Certificated, the CE certificate No. 1P160725.HDN53, for more details, please go for our sales.
