: Define laboratory test parameters and criteria to confirm that a selected insulator will perform reliably in the field. IEC TS 60815-2:2008
The IEC 60815 series is divided by material and system type: IEC/TS 60815-2 - PLSLine
If you are interested, I can provide a comparison of and IEC 60815-3 (Composite/Polymer Insulators) . IEC/TS 60815-2 - iTeh Standards
If you are looking to purchase the document, it is available on standard publishing platforms like BSI or IEC's webstore, often offering non-locked, printable, or multi-user licenses. iec 60815-2 pdf
: Establish your base SPS class using IEC 60815-1.
It is important to note that IEC 60815-2 applies exclusively to materials.
To use the IEC 60815-2 PDF effectively, engineers must first determine the Site Pollution Severity (SPS) class based on environmental monitoring. This measurement relies on and Non-Soluble Deposit Density (NSDD) . : Define laboratory test parameters and criteria to
To translate Site Pollution Severity (SPS) into concrete requirements for insulator profile and creepage distance.
Most utilities have a rule of thumb: "Use 25 mm/kV for clean areas, 31 mm/kV for polluted." IEC 60815-2 blows that simplification out of the water.
Using IEC 60815-2 PDF provides several benefits, including: : Establish your base SPS class using IEC 60815-1
It gives a range (e.g., 31–43 mm/kV). The final choice depends on local history, importance of the line, and economic trade-offs between outages and hardware cost.
The final required creepage distance calculated after applying correction factors to the RUSCD.
