Abstract

Modern power system engineers' primary objective is to modernise the power system by making it more sustainable, intelligent, and reliable. As static, dynamic, and gradually increasing non-linear demands based on electronic devices are integrated, the behaviour of the power system network is changing. The flaws have been successfully detected and protected against over time using traditional protection systems. However, in some of these situations, the protection system is unable to identify the fault because these faults are caused when an energised conductor makes contact with a high impedance object and draws a small amount of current randomly. High Impedance Fault is the common term used to describe this fault type (HIF). Utility companies constantly struggle to find these issues in the distribution system quickly and consistently because of their behaviour. Predominantly the impedance faults can be classified as Low impedance faults (LIF) and High impedance faults (HIF). The LIF can be detected and protected by a conventional protective device. However, if High impedance fault occurs in the system, it is difficult to detect because of the low magnitude current. The overcurrent relay, which smartly detects the Low impedance faults, fails to detect the High impedance faults.
