Nowadays, a clear trend of increase of system voltage to 800 kV AC and above can be observed in the world. This calls for the need of having test facilities to verify the current interruption performance of circuit breakers for such “super grids”. Recent work of CIGRE WG A3.22 and A3.28 led to standardized requirements for the highest system voltages up to 1200 kV, now anchored in the IEC requirements. The present contribution highlights the test-circuits and test-methods that DNV GL’s KEMA Laboratories have developed in recent year to be able to carry out a full test-program of short-circuit tests on circuit breakers up to 1200 kV. For such tests, separate, well-synchronized sources for the supply of fault current and transient recovery voltage (TRV) are required, combined to synthetic test circuits. In this contribution, it is shown how this principle is stretched further to be applied for UHV switchgear.
