Title: Mine electrical power systems. Transients protection, reliability investigation, and safety testing of mine electrical power systems. Volume V--periodic inspection of mine electrical power systems. Open file report (final) 24 Jun 74-15 aug 78

Abstract

This report presents the results of an investigation into the feasibility of periodically measuring parameters of the insulation for a mine electrical power system to detect incipient faults. The variety of insulation parameters evaluated included insulation resistance, dissipation factor, power factor (versus applied voltage), current harmonics, leakage current, infrared radiation, as well as certain circuit breaker parameters and tests. To augment field tests, a program of accelerated life testing was also carried out. Apparent inconsistencies in data were identified as the result of environmental effects, primarily temperature and relative humidity. A series of environmental tests were conducted to develop correction factors that allow reference of measured parameters to standard conditions. A portable data collector was developed to aid in the accurate collection and analysis of laboratory and field data.
