Abstract
This paper proposes a transient simulation model of pole-type distribution transformers for electromagnetic transient studies. The proposed model takes into account the following effects: (1) capacitance between windings and an enclosure and also between primary and secondary windings, (2) skin effects of winding conductors and an iron core, and (3) multiple resonance due to the combination of winding inductance and turn-to-turn capacitance. Thus, the model accurately reproduces the frequency characteristics of a pole-type distribution transformer in a wide range of frequency. The parameters of the model can easily be determined by frequency-characteristic measurements using an impedance analyzer. Because of the above capability, the proposed model enables the accurate evaluation of overvoltages on distribution lines including consumer-side overvoltages. In this paper, a 10-kVA pole-type distribution transformer is modeled, and the proposed model is validated by comparisons between simulated and laboratory-test results.
