摘要：In the last few decades the main focus of utility companies has been on developing diagnostic, location and pin pointing techniques for medium and high voltage cables, despite the fact that most of the installed cable assets on the network consist of low voltage cable. Egyptian distribution network is very complex network and has large lengths of underground cables, which mostly oil paper cables and XLPE cables. The network suffers from an increasingly faults at cable joints, where the main cause is the difficulty of oil paper cable joints which required a skilful technician. Large efforts are spent to categorize the types of faults happen at the cable joints to describe the avoiding methods of these faults. Benefits will be saving of operation cost, time and improvement of system availability and performance to avoid service outage which is a big lost for company and customer.
