1. A mobile apparatus mounted to a motor vehicle for detecting an electric field, comprising:

  • at least one sensor probe, mounted to the motor vehicle, that generates a signal corresponding to an electric field detected by the at least one sensor probe, and wherein the at least one sensor probe comprises at least one electrode;

    a processor, coupled to the at least one sensor probe, that digitizes the signal to form electric field data represented as a plurality of time domain samples, produces field strengths of each of the at least one sensor probes using the plurality of time domain samples, and analyzes the field strengths to identify a voltage anomaly in the electric field, wherein the electric field data is analyzed based on an expected frequency pertaining to the voltage anomaly to locate an energized object proximate a street; and

    an indicator, coupled to the processor, that alerts a user to a presence of the voltage anomaly in the electric field proximate the street.
