Ceramic and glass materials rely heavily on natural washing from rain to remove contaminants. IEC 60815-2 highlights profiles (like aerodynamic or open profiles) that maximize wind and rain cleaning in desert or coastal zones.
Because polymer insulators behave differently than glass/ceramic under pollution, engineers must use Part 2 strictly for traditional materials to avoid dangerous design assumptions. Summary of Application Steps
To put it simply: Officially titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Ceramic and glass insulators for AC systems," this document bridges the gap between theoretical lab data and real-world grime. iec 60815-2 pdf
If you are researching , consider these complementary standards:
This rigorous process ensures that the selected insulator will have sufficient surface length to withstand the voltage stresses in its specific contaminated environment, greatly reducing the risk of pollution flashovers. Ceramic and glass materials rely heavily on natural
The importance of IEC 60815-2 lies in its ability to ensure the safe and reliable operation of electrical systems. Current-limiting fuses play a critical role in protecting electrical equipment and preventing damage to systems during fault conditions. By providing a standardized approach to selecting these fuses, IEC 60815-2 helps manufacturers, designers, and users ensure that their electrical systems are protected against overcurrent and fault conditions.
: Before selecting an insulator, the Site Pollution Severity (SPS) must be determined (often categorized from "Very Light" to "Very Heavy"). Summary of Application Steps To put it simply:
: Adjust dimensions for insulator shape, diameter, altitude, and mounting position.
IEC 60815-2, titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Ceramic and glass insulators for a.c. systems," is an international standard. It provides system designers and substation engineers with a structured methodology to determine the correct size, profile, and creepage distance of ceramic (porcelain) and glass insulators based on environmental severity.
IEC TS 60815-2 is more than just a technical document; it is a comprehensive design guide. Specifically, it details the selection process for ceramic and glass insulators in AC systems, helping engineers determine the necessary dimensions to prevent pollution-related flashovers.
