The Single Earth Wire Return (SWER) is a low cost electrical distribution system. It was developed by New Zealand engineer Lloyd Mandeno in the early 1920s for rural electrification. The system is still used in some areas of New Zealand, such as the King Country where it was nicknamed ‘Mandeno’s clothesline’.
