The primary goal of the specification is to give engineers a methodology to:

: Typically includes scope, normative references, pollution severity levels, the relation between pollution and specific creepage distance, and profile characterization parameters. Appendices

Inland areas with little to no industrial activity.

. NSDD absorbs moisture and intensifies the wetting effect of dew or light rain. Creepage Distance Calculations

This standard applies to surge arresters designed to protect the insulation of power equipment against overvoltages. It covers metal-oxide surge arresters (MOSAs) without gaps and composite surge arresters.

The practical impact of this standard is most visible in the relationship between creepage distance and system voltage. To determine the required creepage distance for a specific insulator, engineers will apply the principles of the standard:

Select a candidate glass disc or porcelain post insulator. Verify profile parameters: Check if shed spacing ( ), projection ( ), and diameter ( ) require correction adjustments.

IEC TS 60815-2 is indispensable for any engineer involved in the design, maintenance, or selection of high-voltage outdoor insulation for AC systems. The release of the 2025 edition marks a significant update, incorporating technical revisions that reflect the latest research and industry best practices. Ensuring that an insulator is correctly specified for its environment is a crucial step in building a safe, reliable, and efficient grid.

Dictates guidelines for Ceramic and Glass Insulators in AC Systems .

Using unauthorized or outdated pirated copies from third-party file-sharing websites poses a severe safety risk, as critical revisions or corrigenda may be missing.

By understanding IEC 60815-2 and its significance, electrical professionals can ensure the safe and reliable operation of electrical systems.
