Applying IEC 60815-2 in Real-World Engineering

Imagine you are a utility engineer tasked with replacing a failed glass insulator string on a 132 kV line running 8 km from a cement factory and 5 km from the coast. Determine SPS class via ESDD/DD measurements or using

6. Selection Procedure (Step-by-Step from Standard)

1. Determine SPS class via ESDD/DD measurements or using the descriptive table (Annex A of standard).
2. Select base USCD from SPS class table.
3. Apply correction factors for insulator shape, diameter, and voltage.
4. Calculate minimum required creepage distance:
   Creepage (mm) = USCD × (V_line-line / √3)
5. Select insulator model meeting or exceeding this value.
6. Verify with test (e.g., fog chamber test per IEC 60507 if required).
