Abstract
New transient recovery voltage (TRV) requirements have been formulated in the standard IEC 62271-100. Test experiences are reported, using the example of an epoxy resin insulated switchgear system, tested in accordance with the new transformer-limited fault TRV requirements. Also, problems and solutions are highlighted related to the testing under short-line fault TRV conditions.
In addition, the importance is emphasized of choosing a proper TRV testcircuit, in relation to the way high-frequency re-ignition current interuption influences the test result.
