Calculate the total creepage distance required for the specific operating voltage of the substation or transmission line. Importance in Power Engineering By adhering to IEC 60815-2, utility companies can: Reduce Maintenance Costs:

Ensure the insulator profile and length can handle localized contamination without triggering an arc.

Once the pollution class is determined, the standard outlines the requirements for: iec 60815-2 pdf

Covers Definitions, Information, and General Principles .

High-density industrial zones or areas exposed to direct, strong sea spray. Calculate the total creepage distance required for the

: The evaluation for selecting appropriate insulator profiles (the shape of the insulator's sheds or ribs) for ceramic and glass insulators has been simplified to make the process more straightforward.

—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 High-density industrial zones or areas exposed to direct,

| Pollution Level | Typical Environments | Reference $L_ref$ (mm/kV) | | :--- | :--- | :--- | | | Desert areas, low industrial activity | 16.0 | | b) Light | Rural areas, minimal industrial influence | 20.0 | | c) Medium | Industrial suburbs, coastal areas with moderate sea spray | 25.0 | | d) Heavy | Heavy industrial zones, dense chemical pollution | 31.0 | | e) Very Heavy | Desert dust storms, direct salt spray | 40.0 |

What is the primary at your site (e.g., marine salt, desert sand, industrial dust)?

The most critical output of the IEC 60815-2 standard is calculating the required . The USCD is the total creepage distance of an insulator divided by the highest rms phase-to-phase voltage of the system.

This specific standard focuses solely on materials that are inorganic (glass or ceramic), providing detailed guidance on how to define the Site Pollution Severity (SPS) and select appropriate insulator profiles to combat those specific conditions. Key Components of IEC 60815-2:2008
