Improvement Research on Transformer Differential Current Protection
Abstract：Transformer differential current protection is simple,reliable and the principle has absolute selectivity.But because of the complex running environment and many influencing factors,some protection monitor has uncertainty.Aiming at the features and status of differential current protection for current transformer,proposes the methods to optimize transformer differential current protection parameters and action logic.The field operation and detailed accident analysis prove that this method can improve the operation of transformer differential current protection quality.
