Current Transformer Saturation Detection Method Based on Artificial Neural Network by Yu. V. Rumiantsev

“…It leads to an underestimation of the secondary current value calculated by the relay protection compared to its true value. Thus, in its turn, results in trip time delay or even in a relay protection devices operation failure, since its settings and algorithms are calculated and designed on the assumption that the secondary current waveform is sinusoidal and proportional to the primary. …”
