Verification

Verified by Research

Verified Against IEC

Grøft Design® has been verified against Technical Brochure 880 (TB 880), issued by CIGRE Working Group B1.56. The verification process not only found that Grøft Design® accurately reproduces the results of TB 880, but in some cases went beyond TB 880, by producing more accurate cable ratings.

Verification with CIGRE TB880

Real World Experiments

Developed for the industry by the industry through several research projects. REN AS have together with SINTEF Energy, Norway's leading research center on power systems, developed and verified the simulations in Grøft Design® with experiments in the field.
