Switchgear laboratory


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 60947 Low voltage switchgear and controlgear
  • 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.
