“…Moisture and occurrence of PD in any high‐voltage apparatus indicate the incipient fault and help in estimation the life time and reliability . Naturally, they are considered as the reliability index of any electrical equipment . At present, even the reliability level of sensitive electronic devices irrespective of being high power or low power is assessed by measuring the moisture and PD levels .…”

“…Air pollution constituents, in rain or fog conditions, cause the formation of a conductive layer which leads to flow of leakage current and discharges on transmission line insulators surfaces [6], [7]. Several investigations for various air contaminants and in different parts of the world have been performed and reported in many articles in the literature [8]- [12].…”

“…1 Pertinent tar depositions constitute of hazardous substances that pollute surfaces to which they are exposed rendering the same non-usable. [1][2][3][4] Naturally, preventive measures are necessary not only to ensure their operating condition but also to minimize the life-threatening human endeavors (tar contains carcinogenic, mutagenic, reprotoxic substances) and environmental endangering situations. 1,2,5 The tar depositions on the surface of the porcelain bushing comprises of numerous, predominantly aromatic species that are dielectric in nature.…”
