New algorithm for judging transformer inrush current based on asymmetry elliptical model of flux and current

Zhao Yongbin Lu Yuping(School of Electrical Engineering,Southeast University,Nanjing 210096,China)  
When the transformer is switched on and energized,the transformer's flux and current will change asymmetrically.When the transformer is under normal or internal windings fault condition,with the influence of hysteresis,the flux and current will approximately correspond to elliptical symmetry change.The flux and current can be transformed properly to the parameters to reflect the symmetry level of the flux and current.A center offset is defined to describe the offset of elliptical center of flux and current in one setting data window.Whether the change of flux and current is symmetric is determined by the half cycle average value of the elliptical center offset.The offset will increase significantly when the transformer is switched on and decrease while the internal winding fault occurs,which makes the offset the criterion to distinguish inrush and fault currents.It can be concluded from the simulation results that offset is a simple,reliable and practical criterion to distinguish inrush and fault currents.
