000000186 520__ $$aA new approach to CT saturation assessment is presented in the paper. Detailed algorithms for decaying DC component measurement and CT saturation prediction are proposed and their accuracy is discussed. The information on CT saturation period is further used for adaptation of the generator / transformer differential protection. Improved stabilization for external faults is achieved by appropriate temporal adjustment of the differential curve for the time period of CT saturation. The protection developed was tested with both EMTP-generated and real world registered current signals.
