Title: Safe Earthing Systems - Part I: Design and lmplementation Guide - Salient Features
Abstract: The traditional approaches to earthing system design are proving inadequate due to increased constraints including increases in system capacity and complexity, the use of microprocessor based equipment in substations, increased interaction with industrial installations (e.g. industries, mines, pipelines and telecommunications networks), reduced substation areas, use of conductive structures, professional liability and tighter financial constraints. In light of the need for clear design implementation and testing methodologies and tools, a research programme was instituted by Shortland Electricity under the auspices of IE (Aust) and ESAA, to produce such a guide. To meet this aim the methods and experiences of engineers in; Australia and overseas power authorities, universities, research institutes, government departments, private organisations and industry standard working groups have been investigated and analysed. The Guide will meet the need for comprehensive, practical understanding and training, and also result in significant cost benefits (between 10-75% over existing methods). However, the primary benefit of the accurate analysis and testing methods are safe economical solutions to the problems facing design engineers. This paper provides a description of the format and scope of the integrated design package, and introduces the co-ordinated design methodology presented in the Guide.
