Detecting short circuits in high-voltage distribution boxes
An overcurrent relay is designed to detect short circuits on the feeder while the overload relay is used to protect the feeder against overheating. At the fault location, there is often a high-power electrical arc that may cause severe damage. When a short circuit occurs, it can cause damage to equipment, disrupt operations, and even lead to safety hazards. The methods for fault detection and classification have become more problematic because of the significant expansion of distributed energy resources. In order to comply with these requirements there is certain information that must be known, such as the value of short-circuit current which can flow through equipment when an electrical fault occurs. These methods range from visual inspections to advanced diagnostic techniques, ensuring potential issues are identified before they escalate into dangerous situations.
