• Description:
  A three-phase program evaluated commercial proximity warning devices, developed and designed a micro-processor-based electrostatic field measurement instrument, and utilized the instrument to investigate the electrostatic fields about powerlines. Phase I consisted of test evaluations of these commercially available proximity devices. Phase II resulted in the design and development of a microprocessor-based distributed sensor ac electrometer that measures the electrostatic field at 17 discrete locations along a crane boom. Under the Phase III program, electrostatic fields around a crane boom were measured by the instrument at 17 high-voltage powerlines of various voltages and geometries. Analysis of the data indicate that the distances at which a single sensor alarm will activate vary by a factor of 3 to 1, due primarily to variations in boom orientation. The results also indicate that in the case of multiple powerlines, a single electrostatic field sensor cannot reliably be used to determine the distance from a powerline.
