Current Transformer Saturation Detection Method Based on Artificial Neural Network
Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2023 When current transformer is saturated, mainly due to the presence of an exponentially decaying DC component in the fault current, its secondary current has a distinctive distorted waveform which significantly differs from its primary (true) waveform.
