Independently Validated Results
ELEK Cable HV calculations are validated against recognised industry benchmark studies and independent numerical analysis to ensure the highest level of accuracy and confidence.
Industry Benchmarked
Cable ratings verified against independent CIGRE benchmark studies, including TB 880 and TB 908, ensuring accurate implementation of IEC cable rating methods and armour loss calculations.
Numerically
Verified
Calculation results independently cross-checked using Finite Element Analysis (FEM) models* to validate thermal performance and current ratings under real-world installation conditions.

Randomly Filled Cable Trays
Ratings for cables installed in bundles in cable trays with options for fire-rated insulation, cable tray covers, custom diversity and solar radiation.
Finite Element Method Module
FEM is the most accurate method for cable current rating calculations.
Beyond IEC 60287 Limitations
Installation methods which can be modelled in FEM includes: any combination of direct buried, multiple backfills, filled troughs and multiple cable circuits.
Accurate Buried Ratings
The IEC standards assume an isothermal (ideal) ground surface whereas FEM considers convection leading to more accurate ratings.
Multiple Backfills
Model areas with different thermal resistivity including multiple separated backfills or zones of soil with different thermal resistivity.
Automatic Meshing
The FEM algorithm automatically meshes the environment as well as all cable components for high accuracy node temperature calculations.
