Calculation of 35kV busbar
The current rating is calculated from the conductor cross-sectional area, material (copper or aluminium), and maximum temperature rise per IEC 61439-1 (typically 70K above 35 degrees C ambient for bare copper). Standard Sizing Choose to calculate by Current (Amps) or Power (kW). Enter your system's parameters (e. Adjust the Safety Factor if needed (default is 25%). This article explains how the calculator works, the standards it follows (IEC and NEC), and what factors influence. The busbar sizing calculator determines the required busbar dimensions based on the continuous current rating, short circuit withstand, and thermal limits for switchgear assemblies. This calculator helps electrical engineers, panel builders, and power system designers to properly size and evaluate bus bars.
