Fault detection in low voltage (LV), medium voltage (MV), and high voltage (HV) cables is essential for maintaining the integrity and reliability of power distribution systems. This process involves the use of specialized diagnostic tools and techniques to locate faults, such as insulation failures, short circuits, and open circuits, within the cable network. By accurately identifying the location and nature of these faults, maintenance teams can perform targeted repairs, reducing downtime and preventing further damage. Effective fault detection ensures that any issues are addressed promptly, enhancing the overall performance and safety of the electrical infrastructure.
