Extensive testing and evaluation of the proximity warning device (PWD) have clearly shown that the concept of using the measurement of the electric field to determine the relative position of a crane with respect to power lines to be flawed. PWDs tested are not dependable as their warning is, in many cases, nonrepeatable and, in some instances, totally unreliable. The devices depend entirely on a measurement of |E| to detect and warn of proximity to high voltage electric power lines. However, the typical |E| configuration produced by the presence of high voltage electric lines is subject to many variables, including but not limited to
