Transmission Line Power Capability

Transmission Line Power Capability

 

one of the principal characteristics of electric power transmission lines. It determines the maximum power that can be transmitted through the line, taking into account all limiting conditions, such as reliability, corona losses, and the heating of conductors and contacts. The power capability depends on the voltages at the termini of the line and on the line’s length and wave characteristics—the characteristic impedance and phasing back ratio (seeTRANSMISSION OF ELECTRIC POWER).
