Next Generation Cable Rating Software - For Everyone!
Use Groft Design® Software to correctly dimension cables, minimize failures, and optimize cable utilization with easy to use ampacity calculations
The cabels for a 3.5 MW EV charging depot using traditional steady-state were running hot. In this case study, by applying time-variable load analysis with real charging patterns, we found actual cable temperatures stay well within safe limits.
Drying of cable backfill soil is becoming a real problem. Dry soil reduces heat transfer away from the cable, Consequently, as the soil dries out, the current-carrying capacity of power cables (ampacity) decreases.
Learn how utilities manage heat in underground power cables. Explore thermal analysis, duct system design, and standards for grid reliability and efficiency.
Grøft Design® accurately reproduces the results of Technical Brochure 880 (TB 880), issued by CIGRE. In some cases, it even surpassed TB 880 by delivering more precise cable ratings.
Last week Marius Engebrethsen presented our paper (SINTEF Energy Research) B5-5 with title “Implementation of finite element analysis and hybrid IEC-models in online ampacity tool” at the Jicable23 conference.
Last week, REN, in collaboration with Energiföretagen, showcased Grøft Design® at Elfack in Gothenburg, one of the largest exhibitions in Northern Europe for energy and electrification.
Last years Christmas gift to Sweden was Grøft Design. Energiföretagen, REN’s sister organization in Sweden, have adapted Grøft Design® to Swedish standards and will sell the software in Sweden.
For the first time, REN had its own stand at CIGRE. Grøft Design®, our software product that makes it easy to plan and design complex cable trenches, was showcased to the world.
With Grøft Design® you can plan and design complex cable trenches and run advanced simulations of thermal resistivity and magnetic field using Finite Element Analysis (FEA)
The Norwegian magazine TU has a nice article from the start of the first research project for Grøft Design®. REN and Sintef Energy, in cooperation with the industry started the project in 2014.
