When one wire is enough: australia's rural consumers benefit from single-wire earth return systems

摘要

In the early 1950s, Australia saw a need to expand its electrical network to provide power to the country's agricultural areas. Because the loads were small and spread over a wide area, financial constraints demanded a network that was economical to construct and maintain, as the return on capital investment would take a lot of time. As a result, Advance Energy, New South Wales, Australia, turned to single-wire earth return (SWER) systems, which had been successfully tried in New Zealand several years earlier.
