The goal of the tests is to check the capacity of switchgears to achieve a high number of operations in abnormal conditions (overload up to 10 times the nominal current) and normal conditions (nominal current).

Three facilities offer very flexible adjustment possibilities:

• Each of the three independent testing stations is supplied by a transformer of 8,4 MVA,
• The transformers can be adjusted on output voltages from:
  • 220 V AC to 1,130V AC 3 phases,
  • 120 V AC to 1,130V AC 1 phase.
• DC voltages range from 290 V to 1,575 V,
• Endurance test up to 5,000 A,
• Overload tests up to 10,000 A,
• Short-circuit capacity of each transformer: 50 kA,
• Loads banks for current and power factor or time constant for accurate adjustments.
