Network authority earthing connection policy case study of an industrial facility expansion

摘要

This paper presents the case of an earthing design for a large industrial site performed in accordance with an inflexible Network Authority management policy resulting in high risk outcomes for both parties. In doing so, the basis of the engineering problem, and the lowest risk solution, are juxtaposed against the requirements of the management policy and the implemented design. With the use of the case study, the limitations and risks of 'single solution policies' are explored, along with suggested ways for policy owners to responsibly permit appropriate engineering design to achieve lowest risk outcomes.
