Abstract

Embodiments of the invention include systems, methods, computer-readable media, and computer programs for determining and locating one or more faults on a power distribution network in regions of high resistivity. Embodiments of the present invention include a plurality of phase breaking devices disposed at outboard ends of a plurality of distribution transformers. Each of the plurality of phase breaking devices is configured, for example, to determine abnormal voltage readings and transmit such readings to a master control station over a GSM / GPRS communication network. According to an embodiment of the invention, the master control station is configured to determine or verify the presence of one or more faults and the location of said one or more faults on the distribution network.

Description

[0001] related application [0002] This application is related to, and claims priority to, US Provisional Patent Application Serial No. 61 / 701,643, filed September 15, 2012, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the claimed invention generally relate to the field of detection of one or more broken conductor or open conductor faults in medium voltage (MV) distribution networks. In a more specific aspect, the claimed invention relates to global system for mobile communications (GSM) and / or general packet radio service (GPRS) communications based methods for detecting A broken line or phase failure in the system. Background technique [0004] Faulty wires pose serious hazards to people, animals and the environment. Faulty wires can occur when live wires come into contact with quasi-insulating objects such as trees, buildings or equipment, or the ground. Such events often cause arcing and flashing...
