High Power Laboratory
Switching capability tests, Short-circuit making and breaking tests, Short-circuit current carrying and withstand tests, Capacitive tests, Tests of arcing due to internal fault, Bus transfer current tests.
Max. Testing Parameters Lab 1:
2 Generators with max. power of 6400 MVA for 3-phase direct test or
short-circuit current for 3 sec. at 11 kV 216/80 kA
2 Synthetic circuits with max. TRV 1150 kV
Single-phase short-circuit current at 35 kV 205/76 kA
20 kV 270/100 kA
Max. Testing Parameters of Lab 2:
Dedicated especially to MV products 1 Generator with max. power of 1250 MVA.
Note: The generators of Lab 1 and Lab 2 can be switched in parallel to get higher output. That means that also short-circuit current tests of surge arresters with pre-failing can be performed.
