Laboratory is intended for short circuit tests of switchgear.
Parameters of AC tests
AC 50/60 Hz – 200 ms:
- 150 kA / 250 V
- 100 kA / 500 V
- 60 kA / 750 V
- 40 kA / 1000 V
- 6 kA / 6 kV
AC 50/60 Hz – 3 s:
- 40 kA / 100 V
Parameters of DC tests
- 50 kA / 1000 V – 200 ms (τ ≤ 30 ms)
- 4 kA / 4 kV – 200 ms
Continuously (low voltage)
- 5 kA AC
- 2,5 kA DC
Tests comply with appropriate IEC, GOST and UL standards, e.g.

- IEC 60269 Low voltage fuses
- IEC 61439 Controlgear and switchgear
- UL 489 Molded case circuit breakers
- GOST-R (ΓOCT P) 50030 Low voltage switchgear
Diagnostics equipment
- 12 channels of 16-bit depth DAQ 50 kHz certified,
- 2 channels of 8-bit depth and 50 MHz bandwith,
- High-speed digital camera up to 1 mil. frames per second,
- Measurement of dynamic pressures up to 10 MPa.
