Single Wire Earth Return for Remote Rural Distribution - Reducing Costs and Improving Reliability Conrad W. Holland, B.E. M.I.P.E.N.Z. Maunsell Ltd., Single Wire Earth Return (SWER) has been used in New Zealand since the 1930s and is still actively used in rural New Zealand, Australia, South Africa and parts of South East Asia. This paper updates the cost structure for SWER and looks at modern innovations that can be applied to drive down costs and improve reliability.

How to Model Single Wire Earth Return Systems (SWER) for Rural Electrification using PSS/Adept - Peter Armstrong, Meritec Ltd. June 2002 A Microsoft Power Point tutorial on how to model SWER systems using PTI's PSS/Adept software. The tutorial gives models of SWER isolating and distribution transformers and guidelines on calculating parameters for SWER systems.
