This paper investigates the voltage distortion phenomenon during no-load testing of transformers, its influence on no-load loss calculations, and a novel measurement technique that is unaffected by harmonics for obtaining transformer magnetization cu

Modeling of 3-legged, 3-phase transformers under DC biasing is a challenging topic due to the need to an adequate representation of flux paths beyond the active part including the tank. The main contribution of this paper is to present a new dual cir

Transformer core modeling is of importance for some transient studies like inrush currents, ferroresonance and geomagnetically induced current. This paper compares a transformer model with different magnetization representations to actual measurement

The paper describes capabilities of a topological model of three-phase, five-limb transformer to accurately represent its response when subjected to geomagnetically induced currents. The model is validated by close agreement of the predicted values a

The main features of a dynamic hysteresis model (DHM) and its implementation into the electromagnetic transient program (EMTP-ATP) are described. A method of fitting the DHM to catalog data is proposed. The implementation of the DHM within a transfor

This paper describes an experience in transformer modeling based on open-circuit test data obtained for a wide range of terminal voltages on the low-voltage side and inrush current measurements on the high-voltage side carried out for different resid

History-dependent and history-independent models of magnetic hysteresis are proposed. Spline approximations to the magnetization curves make these models applicable to major loops of any shape. The H(B) representation of reversal curves permits the d
