Radial distribution test feeders

Many computer programs are available for the analysis of radial distribution feeders. In 1992 a paper was published that presented the complete data for three four-wire wye and one three-wire delta radial distribution test feeders. The purpose of publishing the data was to make available a common set of data that could be used by program developers and users to verify the correctness of their solutions. This paper presents an updated version of the same test feeders along with a simple system that can be used to test three-phase transformer models.
