| Term | Meaning | |------|---------| | | Unified Specific Creepage Distance – creepage distance (mm) divided by √3 × nominal line-to-line voltage (kV). Units: mm/kV. | | SPS | Site Pollution Severity – a classification of pollution levels at the installation site. | | DD | Deposit Density (mg/cm²) – Non-soluble deposit density. | | ESDD | Equivalent Salt Deposit Density (mg/cm²) – Soluble pollution converted to equivalent NaCl. | | Creepage distance | Shortest distance along the insulator surface between metal fittings. | : Improved calculations for altitude, diameter, and the

The primary goal of IEC 60815-2 is to prevent insulator flashovers caused by environmental contamination like salt spray, industrial dust, or desert sand. It specifically covers outdoor high-voltage insulators used in AC systems, including: (cap-and-pin, long rod). Units: mm/kV
