Abstract A three-phase program evaluated commercial proximity warning devices, developed and designed a microprocessor-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.
