IEC 60815-2 standard, titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Glass and porcelain insulators," is a critical international technical document used to ensure the reliability of electrical power networks. It provides specific guidelines for choosing insulators that can withstand environmental contamination, which is one of the leading causes of flashovers and power outages. Core Objectives and Scope
The most valuable asset inside the IEC 60815-2 PDF is . These correlate the ESDD (Equivalent Salt Deposit Density) and NSDD (Non-Soluble Deposit Density) to a required Specific Creepage Distance (SCD). iec 60815-2 pdf
The standard strongly emphasizes that the Pollution Severity Map (informative) is a starting point. Critical substations and lines require actual ESDD/NSDD monitoring per IEC 60507 . IEC 60815-2 standard, titled "Selection and dimensioning of
The document is the second part of the broader , which collectively defines how to manage pollution-related flashover risks in power systems. While Part 1 (IEC TS 60815-1) establishes general principles and definitions, Part 2 focuses specifically on standard materials like porcelain (ceramic) and glass. These correlate the ESDD (Equivalent Salt Deposit Density)
The standard is a critical technical specification for the electrical power industry, specifically titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Ceramic and glass insulators for a.c. systems".
This standard replaces the older IEC 60815 (1986) and moves away from simple look-up tables toward a more rigorous, site-specific design approach. It establishes how to determine the required to prevent insulator flashover based on environmental pollution levels. Key Content & Technical Focus
It is critical to know which part you need.
