National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Evaluation of Proximity Warning Devices. Phase 3. Volume 1.

PB83210260

Publication Date	1982
Personal Author	Nixon, J. H.; Hipp, J. E.; Green, T. C.; Munsch, G. H.; Cater, J. P.
Page Count	95
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.
