Operating Lighting Units on Coal Mine DC Power Systems

• Description:
  Fluorescent, mercury-arc, and sodium-vapor lamps for coal mine face illumination, when powered from dc lines, usually utilize solid-state power supplies. The 300-vdc or 600-vdc electric power from the lines varies widely in level and often contains high-voltage transients that can cause temporary blackouts or permanent damage to the lighting systems. These problems must be guarded against by power-supply design. In this paper, power-supply designs utilized in various present lighting applications are discussed, and the available transient-protection techniques are described. [Description provided by NIOSH]
