Investigation Of Short-Circuit Electromagnetic Force In Three-Phase Busbar System

Busbar system is an effective tool for distributing electricity up to a few kA from the main switch room to the load. Therefore, it should be integrated with a well-known characteristic that can give confidence to the consumer to use the distribution system. A short-circuit test is one of the very i...
