Iskra Instrument for Protective Element Parameters Measurement


Iskra is designed for testing disruptive voltage of gas-filled lightning arresters as well as varistors max. AC operation voltage including one of those installed in different protective devices.

Tested devices:

  • cross protection units;
  • protective gears for wire communication equipment;
  • protective gears for РРС equipment carrier links and base stations;
  • excess voltage suppressors for under 0.4 kV mains;
  • arresters, varistors, suppressors and stabilitrons.

Areas of Use

  • operation of telecommunication equipment,  power plants and automatic equipment;
  • equipment test for electromagnetic effect tolerance.
