Introduction
Electrical powers system is growing in size and complexity in all sectors such as generation, transmission, distribution, and load systems.
An electrical fault is an abnormal condition, caused by equipment failures such as transformers and rotating machines, human errors, and environmental conditions.
An electrical fault is the deviation of voltages and currents from nominal values or states. Under normal operating conditions, power system equipment or lines carry normal voltages and currents which results in a safer operation of the system. But when fault occurs, it causes excessively high currents to flow which causes the damage to equipments and devices.
