Advanced Transmission Line Parameters and Electric and Magnetic Fields Computation Program

EDSA Transmission Line Constants program is designed to calculate electrical parameters of overhead transmission lines. The program also computes the electric and magnetic fields surrounding the transmission lines. This program computes electrical parameters of overhead transmission lines based on the characteristics and positions of the conductors, and applies the matrix-oriented method using Carson's formula.

The program is user friendly and a very powerful tool for practicing power system engineers, and for designers who would like to avoid time consuming and complex longhand calculations of overhead transmission lines based on electrical characteristics and positions of the wires. The program also computes the electric field surrounding the transmission lines.
