The PDF provides exact mathematical equations to correct creepage distances based on altitude, insulator diameter (larger diameters collect more pollution), and mounting angles (horizontal vs. vertical strings).
: Define laboratory test parameters and criteria to confirm that a selected insulator will perform reliably in the field. IEC TS 60815-2:2008
is a technical specification titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Ceramic and glass insulators for a.c. systems" . It provides detailed guidance on choosing and sizing porcelain and glass insulators based on the specific pollution levels of their operating environment. Scope and Application iec 60815-2 pdf
Common principles and global guidelines for both AC and DC systems.
Measures the amount of conductive salt on the insulator surface, expressed in The PDF provides exact mathematical equations to correct
IEC/TS 60815-2 is a Technical Specification titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Ceramic and glass insulators for a.c. systems"
The 2025 edition introduces several significant improvements to its methodology: IEC TS 60815-2:2008 is a technical specification titled
is the shortest distance along the insulator surface between the two metal fittings. Together with the system voltage it gives the specific creepage distance (usually expressed in mm/kV).
, and select appropriate profiles (e.g., standard vs. "fog type") based on the site's pollution severity. Key Sections
