Research performed on arcing faults and their interactions with electrical insulating materials within coal mine power system enclosures is described. Results presented are interim in nature and future research is planned to integrate the simulations that have been constructed as well as to apply developed experimental procedures to the evaluation of electrical insulating materials for use in coal mine enclosures. The research has been divided into several primary areas. These include the development of a theoretical procedure for computation of three-phase and line-to- line arcing fault currents as a function of time, formulation of an arc model based upon thermal-arc plasma properties so that arc voltages and energies may be computed, development of a simulation for pressure and temperature rises when an arc interacts with an electrical insulating material within an enclosure, experimental evaluation of electrical insulating materials in terms of their tendency to support an arc.
