Development of reduced-scale line modeling for the study of hybrid corona

Abstract

A review of the reduced-scale hybrid line model development for the study of hybrid corona phenomena is presented. Techniques to model hybrid corona through the modeling of conductor size and conductor corona onset voltage have been developed. Instrumentation for the reduced-scale hybrid line model has been developed and physical facilities have been designed and constructed. Test series and parameters to be varied were selected for simple configurations with one AC and one DC bundle conductor. Measurements were performed and test data were evaluated and organized. Modeling techniques have been extended to full configurations with three phase AC and bipolar DC line models.<>
