) to prevent tracking and flashover under specific pollution classes. Correction Factors: iec 60815-2 pdf
Practical tips for engineers and students
- Measure both ESDD and NSDD—insulators in industrial zones can have high NSDD that changes behavior differently from soluble salt.
- Repeat measurements seasonally—coastal or agricultural areas show big seasonal swings.
- Consider hydrophobic silicone coatings in areas where cleaning is impractical.
- Combine laboratory data with site measurements; lab tests help understand failure modes, site data give real exposure.
- Use standardized sampling tools and documented procedures to ensure repeatability.
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 Unified Specific Creepage Distance (USCD) required to prevent insulator flashover based on environmental pollution levels.

"Application of IEC 60815 for the Selection of Insulators" (IEEE Xplore): Various IEEE papers analyze the transition from the old IEC 815 (1986) to the current 60815 series. These papers often compare the deterministic approach of the old standard with the statistical approach of the new one. Measure both ESDD and NSDD—insulators in industrial zones
