Proposition and validation of full-order wideband models of two single-phase distribution transformers of different power ratings

摘要

This paper proposes wideband models for two 7.967 kV/240-120 V single-phase transformers with power ratings of 5 kVA and 10 kVA usually applied in distribution networks. The models are validated in time domain by calculating transferred voltages for the application of two different impulse voltage waveforms on the high-voltage side considering two different terminal conditions. The results show good agreement with experimental data.
