  • Description:
    A two-phase program evaluated commercial proximity warning devices and then served to design and develop an automatic electrostatic field strength measurement device with improved performance. The Phase I program consisted of test and evaluation of three commercial proximity warning devices, all of which operate on the principle of electrostatic field intensity measurement for determining proximity to high-voltage powerlines. Performance testing of these devices utilized full-scale cranes and powerline systems and a scale-model facility. Under the Phase II program, a microprocessor-based data acquisition system was designed and developed to collect and measure field strength at distributed points around the crane boom. This unit measures the field strength about a crane boom using 17 distributed sensors. Keyboard control is provided for the equipment operator. Measured field strength values are displayed on a line printer and recorded on magnetic tape. Laboratory testing of this unit demonstrated performance characteristics and field strength measurement accuracy within the design goals. [Description provided by NIOSH]
