Determine the environmental conditions (e.g., coastal salt, industrial dust, or desert sand). Determine SPS Class:

: Allows utilities to specify exact geometric demands to international manufacturers.

(Note: A minor typo – "iec 60815-15-2 pdf" – sometimes refers to the correct standard IEC 60815-2, which is part of the broader 60815 family. See clarification below.)

The fundamental objective of IEC 60815-2 is to guide engineers in choosing the appropriate glass or ceramic insulator design based on the specific pollution severity of a deployment site. The standard moves away from rigid, legacy lookup tables and establishes a sophisticated, deterministic engineering process. The selection methodology follows these primary steps: 1. Assessment of Site Pollution Severity (SPS)

Ceramic and glass insulators for AC systems (the focus of this guide).

Selecting the right high-voltage insulators is critical for power grid reliability. Pollution accumulation on insulators causes tracking, flashovers, and widespread power outages.

The 2025 edition introduces several significant improvements to its methodology:

to verify the chosen configuration under simulated artificial pollution conditions. 2. Navigating the Standard's Structure IEC TS 60815-2:2025 | Standards Australia Store

The standard emphasizes that total creepage length alone is not enough; the geometry of the insulator sheds matters immensely. IEC 60815-2 provides specific design parameters for glass and ceramic profiles, analyzing factors like:
