How to Calculate Cable Ampacity with the Finite Element Method [Webinar]

The Finite Element Method (FEM) is the most accurate technique for calculating power cable ampacity. It's also highly accessible using the latest software packages like ELEK Cable HV. Join us for an insightful webinar designed for electrical power engineers looking to enhance the accuracy of cable ampacity calculations. This technical webinar introduces a practical approach to improving current rating estimates by combining the IEC 60287 standard with the Finite Element Method (FEM). Learn how to overcome the limitations of conventional methods by incorporating numerical modelling to simulate real-world buried cable conditions. The webinar features live software demonstrations using ELEK™ Cable HV, showcasing real examples and concluding with an interactive Q&A. The software used for the modelling was ELEK Cable High Voltage Software.
