A Simple Short Circuit Analysis for Power Networks

Abstract

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.

“…The short circuit current that occurs produces heat which is proportional to 𝐼 2 𝑅. This equation is the heat that arises because of a short circuit, and from this heat, it can damage the insulation of machines, conductor wires, circuit breakers, transformers, and so on [14], [15]. In the process in the field, a short circuit can occur not only due to the heat that arises on the conductor wire but also from external consequences such as a lightning strike, a fallen tree, and so on.…”
