Fast electro‐thermal simulation of short‐circuit tests [PDF]
IET Generation, Transmission & Distribution, 2017 Low‐ and medium‐voltage connectors are designed for a service life of more than 30 years, during which they have to withstand extreme conditions, so it is primordial ensuring their thermal performance. Mandatory standardised short‐circuit tests are required to homologate electrical connectors which are conducted in singular and scarce laboratories, so ...

Development and Testing of a 252 kV/2500 A-40 kA Multi-Break Bus-Coupler Fast Vacuum Circuit Breaker
Energies, 2021 It is effective to open the bus-coupler circuit breaker in case of a short-circuit fault. A fast vacuum circuit breaker (FVCB) is an ideal bus-coupler circuit breaker due to its high velocity.
