The High Power Laboratory (unique in Greece) performs Short Circuit Tests breaking capacity and Interrupting performance tests in High Voltage, Medium Voltage and Low Voltage Electrical Materials.
Main Tests
- Low-voltage switchgear and controlgear assemblies, Low Voltage AC Micro Circuit-breakers, low voltage fuses, portable earthing equipment, Low Voltage relays.
- Short time withstand current and peak withstand current tests:
- High Voltage AC metal-enclosed switchgear and controlgear, Disconnectors and earthing switch, Load switches, Circuit-Breakers, fuse Cut-out 24kV, Current Transformers, Voltage Transformers, Portable earthing equipment, Surge Arresters, Medium Voltage Cables: Joints, End fittings, terminations, connectors etc.
- AC metal-enclosed switchgear and controlgear: Internal arc test 10ka-1s.
- Dynamic Ability to withstand short circuit tests for Power transformers 50-1600 KVA, Routine tests,
- Visual /dimensional inspection, Sound levels measurements.
