900kV 90kJ impulse voltage generator for Indian customer

Our Indian customer installed and commissioned test system with our remote help in Jan,2022.

The system can be used to generate impulse waveform for simulating lightning strokes such as lightning impulse and steep impulse waveform.

Output waveform:

(1) Steep impulse voltage:

>1000kV/us,
Up to 500kV for insulator test
Suitable to test composite suspension and tension insulators
(2) Lightning impulse : up to 810kV without load

Waveform: 1.2±30%/50±20% μs
Efficiency: >90%
