The standard is a critical technical framework for the selection and dimensioning of high-voltage insulators intended for use in polluted conditions. As part of a larger series, Part 2 specifically focuses on glass and porcelain insulators for AC systems, providing the engineering community with standardized methods to ensure electrical grid reliability. The Purpose of IEC 60815-2
A key first step is to evaluate the at the proposed installation site. This involves assessing the expected level of pollution from sources like coastal salt, industrial emissions, desert dust, or agricultural sprays. The SPS is categorized into defined pollution classes (e.g., light, medium, heavy, very heavy).
Without this table, you are under-sizing your insulators by 30-40%, guaranteeing a flashover during the first dry fog season. iec 60815-2 pdf
Extreme environments, such as desert areas experiencing frequent sandstorms or direct coastal spray.
IEC 60815-2 is a foundational standard for modern power grid insulation design. By shifting the industry from a generalized insulation checklist to a precise calculation of Site Pollution Severity and Unified Specific Creepage Distance, it ensures that glass and ceramic insulators can withstand the harsh realities of environmental pollution. For any professional tasked with maintaining or building reliable AC high-voltage systems, the IEC 60815-2 PDF is an indispensable technical asset. The standard is a critical technical framework for
2. Determining the Unified Specific Creepage Distance (USCD)
): The distance between consecutive sheds. If sheds are too close, water droplets can bridge the gap, shorting out part of the insulation. Shed Projection ( This involves assessing the expected level of pollution
