Embodiments of the present invention include systems, methods, computer-readable media, and computer programs to determine and locate one or more faults on a distribution network in a high resistivity area. Embodiments of the present invention include a plurality of open conductor devices positioned on lateral ends of a plurality of distribution transformers. Each of the plurality of open conductor devices are configured to, for example, determine abnormal voltage readings and communicate such readings to a master station over a GSM/GPRS communication network. The master station, in accordance with embodiments of the present invention, is configured to determine or verify the presence of one or more faults on the distribution network and the location of the one or more faults.
