An investigation into the methodology to develop an insulator pollution severity application map for South Africa

The development of an insulator pollution severity application map (IPSAM) for South Africa is being investigated. This work discusses the results that were obtained from directional dust deposit gauges (DDG's) and equivalent salt deposit density gauges (ESDD's) across South Africa. An investigation into the effect of distance-from-seacoast on pollution severity levels is discussed. Correlations between DDG and ESDD and between DDG and corrosion test results are also included.
