Emergency and Cyclic Rating Calculations
The Transient Rating module in ELEK Cable HV Software calculates the emergency and cyclic current rating of cables installed in air and buried cables, in accordance with IEC standards.
Finite Element Method Module
The Finite Element Method (FEM) module in ELEK Cable HV Software calculates the current rating of cables in custom arrangements and goes way beyond the limitations of the IEC Standards. For example, users can calculate the current rating for installations with multiple zones of different thermal resistivity.
Magnetic Fields Module
The Magnetic Fields module in Cable HV Software calculates the magnetic field density in micro Tesla µT occurring around a cable, circuit, or a group of circuits. The calculations are based on the Biot-Savart law which explains the fundamental quantitative relationship between electric current which is flowing and the magnetic field it produces.
