Why can’t DC current be transmitted over long distances like AC current can?
Why can’t DC current be transmitted over long distances like AC current can?
"Answer (1 of 40): It's actually the opposite. DC is preferred for long distance transmission hauls and that's where the economics of a DC line really shine. DC is more efficient than AC at high voltages and has lower line losses. The line has lower losses, no reactive power is needed, and the pow..."
