Current in transmission line
WebThe presence of current-carrying lines in the vicinity also adds to the resistance of the transmission cable; this applies most in three-phase transmission lines. The magnetic and electric fields associated with the current-carrying transmission lines govern the line parameters: series inductance L and shunt capacitance C. WebThe voltage regulation of a transmission line varies with the effect of the line parameters R, L, and C on the line length. In a short transmission line, the voltage regulation …
