Coupled Tests Including Parameters TF and SLF of High Voltage SF6 Circuit Breakers

摘要

Standard short circuit tests of HV SF6 circuit breakers need high power sources and special synthetic facilities. Tests consist of many standard disciplines. Each of short fault disciplines requires high parameters from high power sources. They also require exact measurement and accurately control consequence of switching high current and high voltage circuit of synthetic method. Developing tests are therefore very expensive. The aim of this article is to introduce new point of view on testing by coupled terminal fault and short line fault while reducing high cost of developing tests.
