• Description:
  The purpose of this work is the elimination of safety hazards created by transients, and the objective is to provide knowledge about transients existing in alternating current (ac) and direct current (dc) coal mine power systems. The report covers theoretical background, instrumentation, and experimental investigations. The instrumentation discussion scans measurement problems and considerations plus the development of a low-cost peak-detector. Transient data from in-mine measurements are presented and include high-voltage distribution and DC trolley systems. Unique field exercises are described involving actual power equipment connected on the surface to duplicate typical underground coal mine system arrangements. Transients on high-voltage distribution resulting from vacuum circuit breaker operations could be seen under controlled conditions, and work centered around how surge capacitors affect transients. Using in-mine and staged transient data, specific conclusions and recommendations are made with emphasis on high-voltage distribution. [Description provided by NIOSH]
