The cross-section of a conductor can be easily checked by determining the diameter of the live wires in a de-energized state using a caliper gauge. “ Correct cable sizing is essential for the safe functioning of an. Nexans EASYCALC™ is a reliable cable section calculation program. This free-of-charge tool designed for the professional: electricians, installers, engineers, etc. Correct cable calculation takes into account the correction factors. In COMSOL Multiphysics ®, you can calculate the cross sections of the scatterer in your optical scattering applications. In this article, we will demonstrate this process, in which we continue to build upon the base application built at the start of the course.
