Abstract :
This paper presents the simulation of capacitor bank switching to evaluate the electrical stress to power circuit breaker. The electrical stress consists of inrush current during closing as well as transient recovery voltage and rate of rise of recovery voltage during opening. The studied cases are base case with ideal voltage source, practical system representing the system by several elements and three phase practical switching including the pole discrepancy among circuit breaker poles during closing and opening. The obtained result will be used to as a guideline for specification and procurement of power circuit breaker using in Thailand electrical network.
