The Influence of Exciting Inrush Current of Transformer Differential Protection

Abstract:

The differential protection for transformer is main protection , the unbalance current is the main factor affecting the behavior of the protection. The unbalance current caused many reasons, generally can be divided into steady state and transient state, the transient unbalance current is mainly under the circumstance of exciting inrush current, Containing a lot of harmonic component and harmonic component, based on this the paper studied the harmonic component in the application of power transformer differential protection, and through the simulation analysis.
