Transmission & Distribution (Overhead) Line
Impedance Constants Software

ETAP Transmission & Distribution Line Impedance Constants Analysis module with a user-friendly graphical interface displays the layout of circuit and ground wires for overhead lines. It is an easy to use tool for efficiently sizing existing transmission and distribution lines, designing new lines, verifying the parameters of existing lines, and providing calculated or user-defined impedances for network analysis.

Impedance Constants Analysis Software Key Features
