Iec 60815-2 Pdf -

The IEC 60815-2 standard is a technical guide titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Glass and porcelain insulators." It provides specific rules for choosing and sizing ceramic and glass insulators based on the environmental pollution levels they will face. Key Content of IEC 60815-2

The standard builds on the general principles established in IEC 60815-1 and focuses on the following areas for glass and porcelain:

Pollution Level Assessment: It uses Site Pollution Severity (SPS) classes (Very Light to Very Heavy) to determine the required creepage distance.

Unified Specific Creepage Distance (USCD): It defines the minimum creepage distance per unit of voltage (mm/kV) required to prevent flashovers.

Profile Parameters: It provides guidance on insulator shapes, such as shed spacing, shed overhang, and "creepage factor," which are critical for performance in rain or coastal salt spray.

Correction Factors: Adjustments are made based on the insulator's diameter, as larger diameters typically perform worse in polluted conditions. Relationship within the 60815 Series

IEC 60815 is split into several parts to address different materials: Part 1: General principles and definitions. Part 2: Glass and porcelain insulators (this document). Part 3: Polymer (composite) insulators. How to Access the PDF
