A 220 kV (rms) line crossing a coastal industrial zone in Southeast Asia. ESDD measurements average 0.15 mg/cm².
The IEC 60815 series of Technical Specifications provides guidelines for selecting and dimensioning high-voltage insulators in polluted conditions, covering ceramic, glass, and polymeric materials. The standards are divided into parts defining general principles (Part 1), AC systems (Parts 2-3), and DC systems (Part 4), offering methodologies to determine necessary creepage distances based on environmental severity.
