Correction of current transformer distorted secondary currents due to saturation using artificial neural networks.

Correction of current transformer distorted secondary currents due to saturation using artificial neural networks.

Current transformer saturation can cause protective relay misoperation or even prevent tripping. This paper presents the use of artificial neural networks (ANN) to correct current transformer (CT) secondary waveform distortions. The ANN is trained to achieve the inverse transfer function of iron-cor...
