Evaluation of the performance of line protection schemes on the NYSEG six phase transmission system

This paper describes the performance of different line protection schemes during testing and operation which were used to protect the first commercially operated six phase transmission line in the world-the New York State Electric and Gas 93 kV (phase to phase and phase to ground) line from Goudey station to Oakdale substation. This project was sponsored by Electric Power Research Institute (EPRI), the Department of Energy (DOE), Empire State Electric Energy Research Corporation (ESEERCO), New York State Energy Office (SEO), New York State Energy Research and Development Authority (NYSERDA) and New York State Electric and Gas Corporation (NYSEG).
