Analysis of the DC Bias Effects on the UHV Autotransformer with Rated Load Based on a Reduced-Scale Model Experiment

Resumen

This paper proposes a new equivalent technique, the DC bias current equivalent relationship between the UHV transformer and the reduced-scale model (RSM) is established by means of the identical saturation degree, the proposed RSM is capable to reflect the actual operation of the UHV transformer under DC bias.
