Iec 60815-2 Pdf 💯

When using the official PDF document for substation or transmission line design, follow this execution workflow:

: Unlike generic guidelines, Part 2 provides detailed analysis of porcelain and glass shapes. It evaluates how different "shed" profiles (the disc-like parts of an insulator) perform under specific types of pollution, such as desert sand versus coastal salt spray.

[Site Pollution Severity (SPS)] ➔ [Select Insulator Profile] ➔ [Determine Unified Creepage Distance (USCD)] ➔ [Verify Profile Parameters] 1. Determining Site Pollution Severity (SPS) iec 60815-2 pdf

Creepage length alone does not guarantee performance. The shape of the glass or ceramic sheds must allow natural washing by rain. IEC 60815-2 enforces strict dimensional ratios for profiles: Distance between consecutive sheds. Shed Projection ( ): How far the shed extends from the core.

The standard distinguishes between different aerodynamic profiles: When using the official PDF document for substation

The standard moves away from simply calculating a minimum creepage distance based on pollution severity. Instead, it introduces a dimensioning process that considers:

Determine the environmental conditions (e.g., coastal salt, industrial dust, or desert sand). Determine SPS Class: Shed Projection ( ): How far the shed extends from the core
