Equipment in Power Systems,e electricity has begun to be supplied in the late 1800s, and nowadays it is considered to be an essential commodity. It is a versatile and clean source of energy; it is rather cheap and “always available.” The purpose of a power system is to transport and distribute the electrical energy generated

Simulations as Verification Tool for Design and Performance Evaluation of Switchgears,interaction was made in 1939 when A. M. Cassie (Cassie 1939; Cassie and Mason 1956) published the paper with his well-known equation for the dynamics of the arc (arc model) and then, in 1943, O. Mayr (1943) followed with the supplement that takes care of the time interval around current zero. Much w

Fault Current Limiting (FCL) Devices and Techniques,or existing protection equipment like circuit breakers (CBs). FCLs are generally installed with the goal to lower the available fault current to a level the CB is capable of interrupting safely prior to the CB beginning its opening operation. The FCL limits the fault current to a preset level based
