. It provides specific guidance for choosing and sizing ceramic (porcelain) and glass insulators used in outdoor high-voltage AC systems exposed to environmental contamination. Core Content and Scope

: Define laboratory test parameters and criteria to confirm that a selected insulator will perform reliably in the field. IEC TS 60815-2:2008 iec 60815-2 pdf

A common 146 mm/kV cap-and-pin unit has a creepage of ~320 mm. Number of units needed = 5510 / 320 = 17.2 → 18 units . A typical clean-air 132 kV string might use only 9-10 units. Pollution doubles the requirement. IEC TS 60815-2:2008 A common 146 mm/kV cap-and-pin

Identify appropriate laboratory test methods, such as those in IEC 60507, to confirm that a selected insulator will withstand the specified pollution conditions. Key Technical Concepts Pollution doubles the requirement

: Establish methods to verify performance through natural or artificial pollution tests. Key Technical Parameters
