Abstract :
Evaluation of double contingency faults in an electrical power system can be performed by a number of methods, many of which are not suitable for hand calculation. This paper describes how symmetrical component analysis and three-phase network analysis can both be used to evaluate double contingency ground faults. The two methods are compared and shown to produce the same resultant equation. These results can be used in the evaluation of the single-pole interrupting ratings of low-voltage protective devices in motor control centers and panel boards.
