The necessary transition from Ohmic targets

For more than 20 years leading practitioners have wrestled to find the right balance between efficiency and responsibility with respect to earthing safety criteria. How could one reconcile the contradictions in published targets internationally and within Australia? Quantified Risk Analysis (QRA) based improvements to this pursuit have led to better coordinated and understood criteria and is influencing how earthing is being analysed globally. In contrast some parts of Australian standards, codes and regulations continue to support simple ohmic targets. Does there remain a place for ohmic targets? Or are they a shortcut no longer justifiable? This paper/presentation? will summarize the key elements and present a proposed framework for answering this question.
