Base Package - Cable Manager

Impedance – Cable constants calculation is an easy-to-use tool for positive and zero sequence impedance calculations. It uses the user-friendly graphical interface of the cable editor and the complete ETAP cable library. The calculation considers cable configuration, installation and operating conditions.

Max Induced Voltage – In the Physical page of cable editor, an intuitive and user-friendly calculation tool is provided to perform the calculation of the induced voltage gradient on the shield, sheath or/and armor in V/1000 ft or V/km based on the cable configuration and loading of the cable.

Max stress - A calculation tool used to calculate the maximum voltage stress of the conductor insulation is provided in the Physical page of cable editor.
