Iskra Instrument for Protective Element Parameters Measurement

Purpose

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.

Technical Specifications

  • test voltages within the range of 50...800 V DC (builds up in a saw-like manner at the rate of 100 V per second), max. load current 1mA;
  • Iskra measures static discharge voltage of arresters as well as varistors, stabilitrons and suppressors max. AC operation voltage.

General Specifications

  • Power: mains adapter or a rechargeable battery;
  • Operation temperature: -20 oС...+40oС;
  • Dimensions: 160x85x30 mm;
  • Weight: 0.4 kg.
