  • Air Gap Inductance Calculation for Transformer Transient Model

    by Milad Akbari, Afshin Rezaei-Zare, Muhammad Ali Masood Cheema, Tomasz Kalicki

    Zero sequence characteristic and parameters play a vital role in some transformer transients involving unbalance or saturation conditions such as inrush, ferroresonance, and Geomagnetically Induced Current (GIC). An important parameter of the zero-sequence characteristic is the inductance of the air gap between the core and the tank. Based on a Finite-Element Method (FEM), this paper determines the air gap inductance, considering fringing flux effects. The comparison of the simulation results with an analytical method shows a good agreement for small air gaps but reveals a significant difference for relatively large air gaps. Thus, an inductance enhancement factor (IEF) is introduced to correct the analytical results and facilitate the transformer modeling parameter estimation from the design data. Furthermore, the significance of the accurate calculation of the air-gap inductance is demonstrated in the time-domain simulation of different saturation levels of the transformer core, when the transformer is subjected to GIC.
