The result? The neighboring plant (using old standards) washes every 3 months and flashes over every 18 months. This plant washes every 6 months and has had zero pollution flashovers in 4 years.
(post insulators, bushings). Key Technical Concepts
Whether you are designing a new solar farm in the desert or maintaining a coastal substation, this standard gives you the mathematical proof to justify a more expensive (but longer lasting) insulator.
From Table 2 (Level d → 31–43 mm/kV). Choose 38 mm/kV as a conservative interim value.
