Transformer Windings’ RLC Parameters Calculation and Lightning Impulse Voltage Distribution Simulation

This paper presents a numerical method for calculating resistance, inductance and capacitance matrices of transformer windings. Importance of their precise calculation is shown in the simulation of voltage distribution over the windings for lightning- impulse test. The results obtained in frequency domain analysis are in a good agreement with the measurement data. All the parameters are calculated using the self-developed solvers, the theory and novelty of which are described in this paper. The presented approach allows fast and accurate high- frequency modeling of transformer windings.
