Abstract
A system and method for detecting an arc of a medium voltage power line, such as an underground power line cable, is provided. In one embodiment the method comprises receiving voltage measurement data of the alternating voltage of the medium voltage power line, receiving current measurement data of the current of the medium voltage power line, detecting a current surge based on received current measurement data and upon detecting the current surge, processing the received voltage measurement data to determine whether the current surge initiated during a peak of the alternating voltage. In addition, the method may comprise transmitting a notification of the concurrent current surge. The transmission may be over the medium voltage power line, wirelessly, via fiber, via coaxial cable, or other suitable method. The current surge detection process may also comprise determining that the current surge lasts for less than a predetermined duration.
