based on the specific pollution levels of a site. This part of the standard specifically excludes polymer or composite insulators, which are covered in Part 3 of the 60815 series. Key Technical Concepts Site Pollution Severity (SPS):

: This is arguably the most comprehensive "paper" on the subject. It was developed by the same working groups that informed the IEC 60815 series. It provides the scientific background for the move from "leakage distance" to the "Unified Specific Creepage Distance" (USCD) approach used in the standard.

Inland areas with low industry and low agricultural activity. B (Light): Areas with low-density housing or regular rain. iec 60815-2 pdf

Longer strings add weight and wind load. If the existing tower cannot support 18 units, you either:

): Evaluates how deeply corrugated the under-ribs of the porcelain or glass are. Deep ribs trap air pockets but can accumulate highly localized salt crusts in desert environments.

: Ensures the underside of the sheds stays protected from direct pollution accumulation. Because IEC documents are protected by copyright, official

By strictly adhering to the formulas laid out in the official IEC 60815-2 documentation, utilities can drastically reduce pollution-related outages, optimize maintenance washing schedules, and guarantee grid resilience over decades of service.

IEC 60815-2 is a standard published by the International Electrotechnical Commission (IEC) that provides guidelines for the selection of surge arresters for power systems. Specifically, this part of the standard deals with surge arresters for power systems with voltages above 1 kV.

: Formal logic paths to navigate from raw field measurement data to a final, verified insulator design. Key Technical Concepts Site Pollution Severity (SPS): :

Industrial areas or regions close to the sea with mild winds.

If an insulator profile accumulates dirt easily or washes poorly in rain, the standard requires engineers to increase the required creepage distance using these profile factors. Ceramic vs. Glass Insulator Specifics in Part 2

The standard replaces the older IEC 60815 (1986) and introduces more refined pollution classes and a systematic approach to determining the required Unified Specific Creepage Distance (USCD).

The standard establishes a base USCD requirement for each pollution class: 22.0 mm/kV Class B: 27.8 mm/kV Class C: 34.7 mm/kV Class D: 43.3 mm/kV Class E: 54.1 mm/kV
