This paper discusses the maximum fault resistance, which can be tolerated by a distance relay with Mho characteristic in the case of inter phase, phase to phase and three phase, faults. This is defined as the boundary fault resistance, that in the case of the lower fault resistances, the relay can discriminate between in-zone and out-of-zone faults satisfactorily. The robustness criterion is defined...
This paper discusses the maximum fault resistance, which can be tolerated by a distance relay with Mho characteristic applied at the source node of a distribution feeder, in the case of inter phase, phase to phase and three phase, faults. This resistance is defined as the boundary fault resistance which is the boundary of the distance relay correct discrimination between in-zone and out-of-zone faults...
This paper discusses the variation of distance relay robustness criterion as a function of Mho characteristic shifting angle as well as power system conditions. Boundary fault resistance is the maximum tolerable fault resistance which distance relay can discriminate between in-zone and out-of-zone faults. The robustness criterion is defined on the basis of the boundary fault resistance. In order to...
This paper discusses the maximum fault resistance, which can be tolerated by a communication aided distance relay with Mho characteristic. This is defined as the boundary fault resistance, that for lower fault resistances the relay can discriminate between in-zone and out-of-zone faults correctly. The robustness criterion is defined on the basis of the boundary fault resistance. In order to achieve...
