Capacitor switching is one of the most important sources of generating transient overvoltage and inrush current of electrical power system. Energizing transient may reduce the life span of capacitor banks, damage of power system equipment and insulation failure. This paper, presents three technologies used to mitigate transients caused by capacitor switching. ATP program is used to simulate capacitor...
There are two major switch-on transient phenomena of the capacitor: one is the transient over-voltage and the other is the inrush current. The transients will shorten the lifetime of the capacitor and furthermore they will damage the contactors of the switching device. In this paper, a novel method for mitigating the capacitor switch-on transients is developed. The operation principle of the proposed...
