IEC 60815-2 is a cornerstone standard for modern insulation coordination. By matching the Site Pollution Severity to optimized ceramic or glass shed profiles, power utilities can prevent costly environmental flashovers. For exact calculations, design curves, and profile limits, engineers should consult the authorized PDF version from the IEC webstore or national standards bodies.
The standard is structured to guide engineers through a systematic approach to insulator design. 1. Definition of Pollution Classes (SPS)
By following this rigorous methodology, engineers can avoid the costly consequences of under-specifying (leading to frequent flashovers) or over-specifying (leading to unnecessary material costs and taller support structures).
Many engineering firms and utilities provide free internal access to these standards through corporate subscriptions to databases like IHS Markit or Techstreet.
IEC 60815-2 is a standard published by the International Electrotechnical Commission (IEC) that provides guidelines for the selection and use of surge arresters for high-voltage (HV) power systems. The standard is part of the IEC 60815 series, which deals with the selection and use of surge arresters. iec 60815-2 pdf
Desert regions with long dry spells, or extreme industrial/coastal pollution.
Accessing the official IEC 60815-2 PDF standard document is vital for utility operators, high-voltage equipment manufacturers, and testing laboratories for several reasons:
Guidelines on how to utilize laboratory artificial pollution tests to verify custom insulator profiles.
Part 2 is for ceramic/glass only. For polymeric (silicone, EPDM) insulators, you must use IEC 60815-3 . Polymeric materials have hydrophobicity, which temporarily reduces pollution severity, allowing lower creepage. IEC 60815-2 is a cornerstone standard for modern
To understand Part 2, it helps to see how the complete standard is organized:
Determining the minimum total creepage distance required based on the voltage and pollution class.
Engineers must first quantify the environmental contamination. The standard defines five Site Pollution Severity classes:
High-density industrial areas or regions close to agricultural chemicals. The standard is structured to guide engineers through
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)
) must be multiplied by the baseline USCD, increasing the total required creepage length. Summary of the Insulator Selection Process
The legacy 1986 standard used a rigid lookup system based on four broad pollution levels. IEC 60815-2 establishes a modern, data-driven methodology that optimizes both system reliability and manufacturing costs. 1. Assessment of Site Pollution Severity (SPS)
