Abstract
This report describes field tests that were performed to determine hazard rates for four critical mine power system components: the molded-case circuit breaker, the undervoltage relay, the ground check monitor, and the ground fault relay. Techniques of data analyses are given along with the experimental method and calculations of hazard rates. Detailed descriptions are given of all observed failures. Recommendations are made for improving the reliability of these devices.
