Patent ID: 8868361

Claim:
A hand-held system for detecting impaired electric power equipment, said system comprising: a signal detection circuit adapted to produce an analog output that is proportional to a level of electromagnetic radiation; an analog filter adapted to receive said analog output of said signal detection circuit, said analog filter adapted to prevent aliasing during conversion of said analog output of said signal detection circuit; an analog-to-digital converter in electrical communication with said analog filter, said analog-to-digital converter adapted to convert an output of said analog filter into a digital signal; a digital signal processing circuit adapted to receive said digital signal and identify a modulation component associated with spiking and having a frequency component within a predetermined frequency band; a global positioning system (GPS) circuit adapted to receive location data; a microcontroller in electrical communication with said GPS circuit and said digital signal processing circuit, said microcontroller adapted to process data from said modulation component and said location data; a memory device in electrical communication with said microcontroller, said memory device adapted to store said data related to said modulation component and said location data; and a mapping program adapted to produce a map showing a variation of electromagnetic radiation signal strength with location.
