—based on the specific pollution severity of a site. While Part 1 of the series establishes general principles, Part 2 focuses specifically on: Ceramic and glass materials used in alternating current (a.c.) systems. Outdoor installations such as overhead lines and substations. Performance prediction

Typical cost: ~250–350 CHF (approx. $280–400 USD).

Note: For very severe cases (>2.0 mg/cm² ESDD), custom dimensioning or mitigation (e.g., washing, coating) is required.

IEC 60815-2 — Practical, student-friendly guide

What it is (short)

IEC 60815-2 is the international standard that gives procedures for selecting and testing insulators used on overhead power lines, focusing on how to evaluate pollution performance and determine the necessary electrical stress (power-frequency withstand, switching impulse, etc.) for long-term service in polluted environments. Part 2 specifically covers laboratory and site test methods and guidance for assessing pollution severity and how to apply those results to insulator selection.

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.

If you work in a substation near a cement plant, along a coastline, or downwind of a chemical factory, you know the struggle. The quiet "crackle" of contamination flashovers is the sound of money burning and unplanned downtime.
