1. An apparatus for detecting an electrical field, comprising:

  • at least one sensor probe for generating a signal corresponding to an electrical field detected by the at least one sensor probe, wherein the at least one sensor probe comprises at least one electrode;

    a processor, coupled to the at least one sensor probe, for digitizing the signal to form electric field data represented as a plurality of time domain samples, transforming the plurality of time domain samples into at least one frequency domain sample, analyzing the at least one frequency domain sample to identify a 60 hz voltage anomaly in the electric field, wherein the electric field data is analyzed based on an expected frequency pertaining to the 60 hz voltage anomaly; and

    an indicator, coupled to the processor, for alerting a user to a presence of the voltage anomaly in the electric field.
