Underground power cable on site testing experience using resonant high voltage power supplies and partial discharge ultra wide band methods

Incipient faults detection on underground power cables mitigate the high cost of reparation and the economic losses caused by the interruption in the supply of electrical energy if a fault occurs. On the other hand, with the ability to detect incipient flaws it is possible to establish a program of corrective actions in a scheduled way, which reduces extra cost and prevents overtime while accelerates repairs.
