From 16.6 Hz up to 60 Hz
Max. MVA / kV / kA: 13000 / 525 / 390 kA for 0.42 s

Test Bays:
Laboratory has three large test bays for testing HV apparatus up to rated voltage 1200 kV and two test bays for MV apparatus up to rated
38 kV. Own jetty for testing of large power transformers while on barge.
Several large assembly bays for use by the customers.

Synthetic Installation:

Maximum transient recovery voltage in test bay from the synthetic installations: 2100 kV.

Majority of Tests:
• Short circuit withstand tests
• Short circuit making and breaking tests
• Capacitive and inductive current switching tests
• Load- break tests on MV switchgear
• Internal arc tests on MV and HV switchgear
• Pressure-relief tests on surge arresters
• Short-circuit tests on HVDC switchgear
• Short-circuit withstand tests on transformers up to 800 kV
Short-circuit tests can be carried out on all MV, (U)HV components such as switchgear, line traps, disconnectors, earthing switches, arresters, fuses, cables & cable accessories.
