1. A power line proximity sensing and warning system for use by an operator of machinery operating near a high-voltage power line, comprising:
a loop antenna disposed on a structure of the machinery that is movable near the power line; a signal processor in communication with the loop antenna, the signal processor configured to send test signals through the loop antenna and receive field strength signals from the loop antenna generated by an electromagnetic field from the power line; and a micro-controller in communication with the signal processor that interprets the received field strength signals and compares the received field strength signals to first and second preset, user-adjustable sensitivity levels, generates is proximity signal, graphically displays the proximity signal on a color display, causes an audible signal to be generated to audibly warn the operator when the proximity signal exceeds the first preset sensitivity level, and automatically shuts down the machinery when a received field strength signal exceeds the second preset sensitivity level, wherein the second preset sensitivity level exceeds the first preset sensitivity level, and each of the first preset sensitivity level and the second preset sensitivity level is user adjustable.
