IEC 60815 is split into several parts to address different materials: Part 1: General principles and definitions. Part 2: Glass and porcelain insulators (this document). Part 3: Polymer (composite) insulators. How to Access the PDF
is a critical technical specification for power systems engineering. It provides a standardized framework for selecting and sizing porcelain and glass insulators to ensure reliability in environments where dust, salt, or industrial pollutants could otherwise cause catastrophic electrical flashovers. iTeh Standards Purpose and Scope iec 60815-2 pdf
| SPS Class | Typical Environment | ESDD (mg/cm²) | Recommended USCD (mm/kV) | |-----------|---------------------|---------------|--------------------------| | a – Light | No industrial, inland, low density housing | < 0.03 | 16 – 20 | | b – Medium | Industrial areas, moderate coastal | 0.03 – 0.10 | 20 – 25 | | c – Heavy | Heavy industry, high coastal salt, desert with dust | 0.10 – 0.60 | 25 – 31 | | d – Very Heavy | Desert with salt/conductive dust, sea spray, high ESDD | 0.60 – 2.0 | 31 – 43+ |
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" I understand you're looking for a full report
. The standard's latest 2025 revision had simplified the profile suitability checks, confirming that for these exact coastal conditions, alternating sheds with a high creepage-to-clearance ratio were the only way to prevent a total blackout.
4. Determination of Required Specific Creepage Distance
Based on the pollution class, the standard provides a table (Table 2 in the original document) that gives the minimum nominal specific creepage distance (in mm/kV line-to-line voltage). Part 2 : Glass and porcelain insulators (this document)
Some of the key requirements specified in IEC 60815-2 include:
