Transformer differential protection unexplained errors, significantly increased risk of rejection action, safety and security to the grid

Transformer differential protection unexplained error, refused action probability increased significantly, to the power grid safety and security, but also affect the normal conduct of industrial production. Since the transformer also includes a circuit and various circuit coupled magnetic core, making the transformer during the closing operation,  mcb circuit breaker system failure is often accompanied by removal of complex electromagnetic transient process that requires multi-disciplinary knowledge to carry out these processes more reasonable analysis. However, so far, on the transformer  power transformers  transient analysis of complex  Circuit breaker  theory is still relatively weak, and a thorough study of the mechanism of occurrence of failures or disturbances and characteristics found through a variety of complex transient disturbances transformer Differential Protection abnormal behavior of the real action reasons.
