Radial distribution test feeders

In recent years many digital computer programs have been developed for the analysis of unbalanced three-phase radial distribution feeders. Because of the wide variation of the assumptions made in the development of the programs, there is a need for benchmark systems for comparison testing of the various programs. Complete data are presented for three four-wire wye and one three-wire delta radial distribution feeders. It is hoped that developers of distribution analysis programs will use these test systems to test their programs.<>
