Bureau of Mines Research on Trailing-cable-fault Locators.
NTIS: PB 288 192 :18 pages
This Bureau of Mines publication describes several fault locators and methods, including time domain reflectometers, a frequency domain reflectometer, tone generators, an infrared method, the murray loop method, and high-voltage "click" methods. The Bureau of Mines has been conducting research into these methods for several years to improve mine safety and facilitate production through rapid, safe location of trailing-cable faults. The problems encountered in practical applications are discussed, and schematic diagrams of several instruments fabricated by the Bureau are presented. Since no present single method of locating trailing- cable faults is universally applicable, a kit composed of several of the more promising fault locators is advisable.
