Groza Instrument for Protective Equipment Parameters Measurement
Groza is designed for testing and parameter measurement of excessive voltage and excess current protection equipment including:
- cross protection units;
- protective gears for wire communication equipment;
- protective gears for РРС equipment carrier links and base stations;
- current and voltage protective elements;
- excess voltage suppressors for under 0.4 kV mains.
- operation of telecommunication equipment, power plants and automatic equipment;
- electronics development and production;
- equipment test for electromagnetic effect tolerance.
The scope of supply includes controllable adapters rendering it possible to test different types of protective gears inclusive of multiple-pair ones.
For computer-assisted operation, measurement data archivation and composition of resulting documents are possible.
The device generates:
- 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;
- test current within the range of 10...200 mA (is set at a pitch of 10 mA) completed with <А2> self-contained supply adapter only.
- arresters discharge static voltage;
- varistors, stabilitrons and suppressors max. AC operation voltage;
- operating current of ceramic and polymer posistors and fuses;
- protective gears and units insertion resistance (both wires simultaneously using <А2> and <А4> adapters only).
- Power: mains adapter or a rechargeable battery;
- Operation temperature: +5oС...+40oС;
- Dimensions: 200x100x40 mm;
- Weight: 0.6 kg.
