Once the SPS class is established, IEC 60815-2 helps determine the . The USCD is the total creepage distance of the insulator divided by the highest operating voltage of the system (expressed in mm/kV).

IEC provides ranges mapping ESDD/NSDD to pollution severity levels (light, medium, heavy). These categories inform design choices: higher pollution → larger creepage distance or hydrophobic/recoverable surfaces.

Offer excellent mechanical rigidity and flexible shed manufacturing options, but sub-surface micro-cracks require specialized testing to detect.

The document is the second part of the broader , which collectively defines how to manage pollution-related flashover risks in power systems. While Part 1 (IEC TS 60815-1) establishes general principles and definitions, Part 2 focuses specifically on standard materials like porcelain (ceramic) and glass.

IEC standards are copyrighted. Obtain the official IEC 60815-2 document from authorized sources: IEC Webstore, national standards bodies (e.g., ANSI, BSI, DIN) or institutional libraries. University libraries often provide access. Avoid unauthorized PDF copies.

The standard is a technical guide titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions – Part 2: Glass and porcelain insulators." It provides specific rules for choosing and sizing ceramic and glass insulators based on the environmental pollution levels they will face. Key Content of IEC 60815-2

IEC 60815-2 is a specific part of an international standard series titled "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions."

The IEC 60815-2 standard covers various aspects of current-limiting fuse selection, including:
