Before diving into the selection procedure, it is helpful to understand several key terms that appear throughout IEC 60815‑2.

USCD is the total creepage distance of an insulator divided by the highest operating voltage of the system (expressed in mm/kV). IEC 60815-2 maps the SPS classes to minimum nominal USCD values: : 22.0 mm/kV Class B : 27.8 mm/kV Class C : 34.7 mm/kV Class D : 43.3 mm/kV Class E : 54.1 mm/kV 3. Insulator Profile Selection

SPS is quantified using parameters like Equivalent Salt Deposit Density (ESDD) and Non-Soluble Deposit Density (NSDD), or Site Equivalent Salinity (SES).

If you are dealing with standard porcelain cap & pin or long rod insulators in an AC substation or overhead line,

IEC 60815-2 is titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Ceramic and glass insulators for AC systems." Before diving into the selection procedure, it is

Formulations to adjust creepage distances based on insulator diameter. Large-diameter station posts collect more pollution and require higher creepage.

: Specific rules for DC systems (under development/upgrades). Core Methodology of IEC 60815-2

: It prevents "over-engineering" where insulators are unnecessarily large and expensive, while ensuring they aren't so small that they risk frequent outages. Insulator Profile Selection What is the (e

Obtaining the official IEC 60815-2 PDF is essential for execution because the standard contains critical calculation tools, including: : Graphs plotting the correction factor ( Ktcap K sub t ) against the average diameter ( Dmcap D sub m

Understanding IEC 60815-2: Guidelines for Selecting Insulators under Polluted Conditions

) must be multiplied by the baseline USCD, increasing the total required creepage length. Summary of the Insulator Selection Process

The standard gives structured guidelines to help engineers:
