1. A method of discriminating power system sources of interference from ambient interference and other interference sources, the method comprising:

  • sensing a signal from a targeted source;

    spectrally analyzing the sensed signal to detect a spectral characteristic related to power system interference sources, wherein said spectrally analyzing comprises;

    detecting a portion of the sensed signal occurring within a frequency interval related to a power system frequency; and

    providing the operator indication representative of a magnitude of said detected portion; and

    providing an operator indication when the spectral characteristic is detected.
