Performance and test criteria for dc fuses, phase 1
Abstract
The development and test criteria for dc fuses used in coal mines is examined. Field tests are conducted in 10 coal mines in which transients are initiated on the dc system from which the parameters of the dc mine electrical power system could be determined. The data processing involves the use of a Fourier analyzer to filter noise and fit an exponential curve to the field waveforms. From this data analysis is possible to find the dc sysatem resistance, inductance, and time constant. A survey of nationally recognized laboratories is conducted to establish that the recommended test criteria are practical.
