Protective Relay System Using PCM Transmission Method [PDF]
, 1971 In this paper we deal with a new system of protective relay in which the informations on line currents at the both terminals of power line are exchanged by the PCM transmission method to detect a fault in the power line.

Discovering decision algorithm from a distance relay event report [PDF]
, 2009 In this study rough-set-based data mining strategy was formulated to discover distance relay decision algorithm from its resident event report. This derived algorithm, aptly known as relay CD-prediction rules, can later be used as a knowledge base in ...
