SSG Series Impulse Current Generators


The Haefely SSG 200-180 / 100-150 is used for exponential current impulse (ECI) 1/20 µs, 4/10 µs, 8/20 µs and lightning current impulse (LCI) 10/350 µs applications with impulse current amplitude up to 200 kA. Impulse current testing is mainly used for testing arrestors and varistors, but is also ideal for testing building protection elements, airplanes, helicopters, and wind turbine blades, etc.


  • Advanced flexibility
  • Long service life
  • Fast impulse repetition rates
  • Advanced stability
  • Automation
