: The standard analyzes how different shapes (e.g., standard, anti-fog, or open profiles) perform under various types of pollution like salt spray or industrial dust.
: Areas far from the sea and clean industrial zones.
: High-density industrial zones, or coastal regions exposed to sea spray.

2. Determination of Required Reference Creepage Distance (USCD)
Inland areas with low industry and low agricultural activity. B (Light): Areas with low-density housing or regular rain.
: The evaluation for selecting appropriate insulator profiles (the shape of the insulator's sheds or ribs) for ceramic and glass insulators has been simplified to make the process more straightforward. : The standard analyzes how different shapes (e
By following the guidelines and recommendations outlined in IEC 60815-2, users can ensure that surge arresters are selected and used effectively to protect HV power systems against overvoltages and surge events.
: Ceramic and glass are hydrophilic (water-spreading) materials. When polluted and wet, they form a continuous water film, increasing leakage currents. Therefore, they generally require larger diameters or longer creepage distances compared to hydrophobic (water-repelling) composite materials under identical pollution levels.
is a Technical Specification that guides engineers on the selection and dimensioning of ceramic and glass insulators intended for use in polluted conditions on a.c. systems. It is part of the broader IEC 60815 series, which replaced the aging IEC 60815:1986 technical report. Are you designing for a , desert , or industrial environment
To successfully implement IEC 60815-2 during substation or transmission line design, follow this sequence:
What is the (e.g., coastal, desert, industrial)?
Because water films form readily on glass and ceramic, the geometry governed by IEC 60815-2 is the primary defense mechanism against flashovers:
