1. A fault location detection system comprises: an Electromagnetic Interference (EMI) detection module including an RF antenna that detects EMI signals and converts the EMI signals into electrical signals; a memory for data storage; a motor for rotating the antenna wherein the motor rotates the antenna and EMI measurements are taken by the EMI detection module and converted to electrical signals, the motor then rotates the antenna to a next angle of interest and once again measurements are taken by the EMI detection module and converted to electrical signals, wherein the measurements are repeated for a plurality of different angles of interest; an analyzing module for analyzing a spectral content of the electrical signals to identify a fault; a movable housing in which the EMI detection module, the antenna, the memory and the motor are housed and which is moved from position to position in an area in which EMI measurements are taken; a location recorder to record a location of the housing when the EMI signals are detected; and a processor for using the analyzed signals and recorded location of the housing to determine a location of the fault.
