Abstract

"The primary objective of this investigation was to determine the general applicability of Single Phase Earth Return(SWER) system for rural electrification where the load density is low, for example electrification of farms and small villages in emerging nations. The limitations of SWER system of distribution are many and it is necessary to make judicious use of such transmission. In this investigation the construction costs of transmission and distribution by SWER system is compared with single phase and three phase systems for loads of 25KVA and 50KVA. Phase converters are required to operate a three phase motor on a single phase supply. Three different types of static phase converters are discussed and their merits and costs are compared. Four different types of grounding systems are discussed in this study. The heating of earth electrodes due to continuous ground current flowing through the electrodes is investigated. Co-ordination of SWER systems with telecommunication lines is discussed in detail. Danger to humans and animals due to potential gradient at the surface of the earth in the vicinity of the grounding system caused by continuous ground current is also investigated in this study"--Abstract, page ii.
