NTIS: PB 295-206 :212 pages
Research performed on arcing faults and their interactions with electrical insulating materials within coal mine power system enclosures are described. These include (1) the development of a theoretical procedure for computation of three-phase and line-to- line arcing fault currents as a function of time, (2) formulation of arc and tracking models, (3) development of a simulation for pressure and temperature rises when a fault interacts with an electrical insulating material within an enclosure, (4) experimental evaluation of electrical insulating materials and (5) integration of the above research areas to form overall procedures for theoretical and experimental evaluation. Consideration was given to the possible effects of an internal methane-air explosion within an enclosure as well as the potential influence of utilization-voltage- level, conductor spacings, and enclosure venting.
