The Electricity Trust of South Australia (ETSA) has experienced powerline failures due to corrosion across the State. The cost of failure in terms of loss of revenue and customer inconvenience is very high. Recent investigations in the measurement of atmospheric corrosivity have highlighted corrosivity mapping as a sensitive and cost-effective means of characterising a regions’ levels of atmospheric corrosion.

Late in 1989, ETSA established a project to measure and map the atmospheric corrosivity levels throughout South Australia. Preliminary results are now available in the form of interim recommendations for materials selection and an atmospheric corrosion map of the State of South Australia for one year.
