Cable Ampacity Calculations using the Finite Element Method [Technical Webinar]

ELEK Cable HV Software was used for all simulations. 👉 Get a Free Trial: https://elek.com/electrical-software/... This technical webinar provides a comprehensive guide to performing cable ampacity (current rating) calculations using the Finite Element Method (FEM), validated with CIGRE TB 963 and compliant with IEC 60287 standards. The session is designed for electrical engineers, system designers, and researchers involved in HV cable design, rating, and installation analysis. 🔍 Topics Covered IEC 60287 Current Rating Calculations and Limitations Understand the analytical equations behind IEC 60287, their assumptions, and where they are applicable or fail for complex installations or shallow burial depths. Finite Element Analysis (FEM) for Cable Ratings Learn how FEM overcomes IEC limitations by accurately modelling soil layers, convection, and heat transfer, and how it achieves verified accuracy within 0.4% of CIGRE benchmark results. Combining IEC and FEM Methods See how hybrid IEC–FEM approaches utilise standard thermal resistance networks, replacing external resistances with FEM-calculated values for enhanced accuracy. Meshing, Boundary Conditions, and Sheath Bonding Discover how cable geometry, soil boundaries, and bonding configurations (solid, single-point, cross-bonding) affect sheath losses, current ratings, and standing voltages. Modelling Complex Cable Installations Includes examples for windfarm export cables, multi-circuit ducts, solar farms, backfilled trenches, air-filled and water-filled ducts, and multiple casings. Soil Drying and Thermal Resistivity Modelling Explore dynamic thermal resistivity modelling, temperature-dependent soil drying effects, and how FEM captures non-isothermal ground behaviour missed by IEC formulas. Verification and Validation ELEK Cable HV’s FEM calculations are validated against CIGRE TB 963, TB 908, and TB 880 case studies—proving compliance and accuracy across AC and HVDC installations. 🧩 Example Demonstrations 132 kV XLPE cables in HDPE ducts and backfill Multiple circuits in shared casings Solar farm DC and MV cable corridors FEM vs IEC comparison of current ratings under soil drying conditions ⚡ Key Learning Outcomes When to apply IEC 60287 vs FEM for HV cable ampacity studies How to model complex environments (duct banks, casings, multi-layer soils) How FEM improves thermal modelling, safety margins, and design confidence
