Webinar (APAC Time) - Accurate HV Cable Rating Calculations: Fundamentals of the Finite Element Method
Luma Webinar Description
Join us for a deep-dive technical webinar designed for electrical engineers, consultants, and system planners who want to master the fundamentals of high-voltage cable ampacity calculations using the Finite Element Method (FEM).
While the IEC 60287 standard has long been the industry benchmark for current rating calculations, its assumptions often limit accuracy in real-world scenarios. FEM extends these capabilities by modelling complex installation environments with far greater precision—capturing effects such as soil non-uniformity, thermal interactions between multiple circuits, and air convection in ducts and pipes.
This session introduces the fundamentals of FEM-based current rating analysis and provides practical demonstrations showing how these methods can be applied in day-to-day HV cable design work. Special attention will be given to soil Dryout effects, cyclic load factors, and installations involving multiple cables in the same duct or pipe, where mutual heating and constrained cooling make accurate ratings essential.
What You’ll Learn:
IEC 60287 vs FEM – Understand the limitations of analytical methods and how FEM improves rating accuracy for complex installations.
Soil Dryout Mechanisms – Learn how moisture migration alters soil thermal resistivity and how FEM captures these dynamic effects.
Load Factor and Cyclic Ratings – See how time-varying loads influence cable ampacity and how FEM quantifies these effects for real projects.
Multiple Circuits in Ducts – Explore advanced calculations for mutual heating, unequal loading, and practical duct bank configurations.
Cables in Pipes and Casings – Discover how FEM models air, grout, and water-filled conditions, as well as their impact on thermal performance.
Live Demonstrations – Watch practical workflows in ELEK Cable HV software, with examples covering direct burial, ducted, and pipe-installed HV circuits.
Whether you’re addressing sheath loss concerns, designing new HV transmission circuits, or seeking to ensure best practice for compliance and safety, this webinar will equip you with the understanding, tools, and confidence to optimise your HV cable system designs. Don’t miss this opportunity to deepen your expertise and safeguard your cable assets for the long term.
