1. Overview of the comparison
We have benchmarked our Cable HV Software current rating results for 110 kV cables against the well-known software CYMCAP. We have shown the results are virtually identical (under 1.5 % difference).
The full CYMCAP reports linked in the table were produced by an authorized user. The Cable HV reports for equivalent conditions are also attached.

Cable HV complies with Standards: IEC 60287 for steady-state and IEC 60853 for transient ratings. We use the latest editions of these Standards. The results above were performed in 2014 for CYMCAP (rev. 5.3b) and 2020 for Cable HV (V3.7.2) and so this may be the source of some minor differences because the relevant Standards have been updated since 2014 including IEC 60287-1-1.
