“…But in real applications, the CB operating time may change. The variation of closing time of the CB contacts is assumed to change as a Gaussian distribution [5]. The value of the rate of decrease of dielectric strength should exceed the maximum derivative of the applied voltage for proper operation of CB.…”

Abstract. This study investigates the transient behavior of short circuits in power circuits. The circuit consists of two part; input part and load part. These two parts are connected with a circuit breaker switch. The circuit works in two modes; first mode is when the switch is open and second mode is when the switch is closed. This study analyses the circuit when the switch is closed. The analysis is done with different types of closing angle. The analysis is done by forming state equations and those equations are solved numerically by using Matlab. The analysis and conclusion is performed by observing the behaviors of the graphs.

This study investigates the transient behavior of power circuits with sinusoidal input. The circuit consists of two part; input part and load part. These two parts are connected with a circuit breaker switch. The circuit works in two modes; first mode is when the switch is open and second mode is when the switch is closed. This study analyses the circuit when the switch is closed. The analysis is done with different types of load that is highly inductive load, highly capacitive load and short circuit load. The analysis is done by forming state equations and those equations are solved numerically by using Matlab. The analysis and conclusion is performed by observing the behaviors of the graphs.

“…According to the results of [10], application of magnetic voltage transformers, instead of capacitive voltage transformers, helps to discharge the trapped charge. Therefore magnetic voltage transformers (MVT) will cause overvoltages to reduce.…”

“…Therefore magnetic voltage transformers (MVT) will cause overvoltages to reduce. Effect of controlled switching or point‐on‐wave switching, on the reduction of switching overvoltages, is considered in [10, 11].…”
