20kV 10kA Surge Generator

Surge generator (combination wave generator) can be used to generate impulse of exponential shapes to perform high energy surge tests. The system can output 8/20μs, 10/350μs, 10/700μs, 5/300μs according to the customer's requirement.

Additional Product Information

Features & Benefits
  1. Different impulse modules for up gradation in the future, easy for operation
  2. Automatic polarity switching
  3. Peak voltage and current monitoring
  4. Integrated large test cabinet with dimension of 40*40*30cm
  5. Open structure for expand waveforms
  6. Easy operation and maintenance
  7. Liquid insulation in the impulse capacitors is made of castor oil which offers optimal environmental compatibility (no PCBs). The impulse capacitors have very low inductance, high quality and long service life.
  8. Considerate safety measures
  9. Door safety interlock



SPD testing, surge immunity test for electrical and electronic equipment to unidirectional surges caused by overvoltages from switching and lightning transients
