900kV 90kJ impulse voltage test system to India

HVGrand just received an order from our Indian customer, one of the largest insulator manufacturers.

We will deliver 900kV 90kJ impulse voltage test system in July,2021.

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/ms, wave front timeT1= 500ns approx
• Up to 600kV 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%
