Covers Definitions, Information, and General Principles .
: Choose a profile type (e.g., standard, anti-fog, or aerodynamic) from the approved profiles in the Part 2 PDF.
: Spend at least one full year monitoring ESDD/NSDD levels or directional dust leakage currents at the target site.
Understanding IEC 60815-2: A Guide to Selecting Insulators for Polluted Conditions iec 60815-2 pdf
Larger diameters typically require more creepage. Altitude: Corrections for air density at higher elevations.
: It uses Site Pollution Severity (SPS) classes (Very Light to Very Heavy) to determine the required creepage distance.
The is not just a technical document; it is a critical risk management tool for every utility, railway, or industrial facility that operates high-voltage AC equipment in less-than-ideal environments. By providing a clear, stepwise methodology—from pollution classification to creepage distance selection and correction factors—it ensures that your insulators will withstand the harshest combination of salt, dust, and fog. Covers Definitions, Information, and General Principles
: Assess the suitability of different shed designs (e.g., standard, fog, or open profiles) for specific pollution types.
The standard is structured to guide engineers through a systematic approach to insulator design. 1. Definition of Pollution Classes (SPS)
