Current in transmission line
WebMost transmission lines in the U.S. are alternating current. 3. What is the difference between low voltage and high voltage lines? ... What factors are taken into consideration … WebCommon Mode Current. Transmission lines may have another mode, conducting currents known as parallel or common mode currents. Common mode current is the portion of conductor currents not matched by exactly opposite and equal magnitude currents. This is the portion of total current responsible for a feedline behaving like a single wire line.
