A Probabilistic Analysis of Electrical Equipment Vulnerability to Carbon Fibers.

Abstract

The statistical problems of airborne carbon fibers falling onto electrical circuits have been idealized and analyzed. The probability of making contact between randomly oriented finite-length fibers and sets of parallel conductors with various spacings and lengths has been developed theoretically. The probability of multiple fibers joining to bridge a single gap between conductors, or forming continuous networks has been included. From these theoretical considerations, practical statistical analyses to assess the likelihood of causing electrical malfunctions have been produced. These statistics have been confirmed by comparison with results of controlled experiments. (MM)
