Abstract
Embodiments of the present invention are directed to a method and fault detection system for detecting and identifying the location of faults in underground power lines that can effectively and quickly identify faults in underground power lines. Embodiments can provide a method and fault detection system that quickly identify faults in a power grid that result from open circuits or short circuits in underground conduits. A specific system for fault detection of power lines in a network having one or more substations and corresponding one or more manholes for access to underground lines, includes: a sensor device for each manhole, wherein the sensor device is capable of detecting a magnetic field generated by a power line and can send a signal through a fiber optic cable, the signal including a unique wavelength identifier; and a communication device for each substation for transmitting the signal from the sensor device to an operator.
