1. A mobile apparatus, configured for mounting to a motor vehicle, for detecting an electric field produced by an object energized by a voltage anomaly, comprising:

  • at least one sensor probe to detect the electric field and to provide a first signal corresponding to the detected electric field;

    an analog to digital converter to digitize the first signal to provide a plurality of time domain samples, each sample representing a magnitude of the electric field;

    a signal processor to filter the plurality of time domain samples according to a desired frequency pertaining to the voltage anomaly and to provide a second signal representing a magnitude of the electric field at the desired frequency; and

    a computer to receive the second signal and to provide an indication of the magnitude of the electric field at the desired frequency.
