    摘要： This invention relates to a method of, and a system for, monitoring electromagnetic interference. The method comprising capturing a plurality of time domain waveforms, and a plurality of scatter plots; receiving the plurality of captured time domain waveforms and scatter plots; applying a fast fourier transform (FFT) to each of the received time domain waveforms as it is received thereby to receive FFT outputs; storing the FFT outputs in a database; generating a statistically representative spectrograph or spectrogram in the frequency domain based on at least the stored FFT outputs and scatter plots or data associated with the scatter plots, combining constituent FFTs of the statistically representative spectrograph or spectrogram in such a manner as to emulate the result that would be produced by an EMI (Electromagnetic Interference) receiver or spectrum analyser; and combining resultant outputs from a number of iterations of this process to produce a final result (EMI spectrum).

    摘要： A fault location detection method includes detecting an EMI signal and analyzing the spectral content of the electrical signal to identify a fault. A location recorder records the location of the system when the EMI signals are detected and a processor analyses the EMI signals and records the location of the system to determine a location of the fault. A memory includes an aerial photograph of a geographic location within which faults are to be detected and wherein the processor overlays the position of the faults on the aerial photograph. In addition, a transparent intensity map is superimposed onto a satellite photo of a geographic location and this is displayed to a user.
