Which of the following is the main advantages of AC transmission system over DC transmission system? Right Answer is: Less losses in transmission over long distance.

What is the advantage of AC power transmission?

AC power transmission is cheaper and more efficient in voltage stepping using transformers. This leads to efficient electrical energy transmission through power lines. This efficient transmission helps power companies and the consumer to save lots of money.

What is the major advantage of AC transmission and distribution?

A major advantage of alternating current is that its voltage can be modified relatively easily using a transformer, which allows power to be transmitted at very high voltages before being taken down to safer voltages for commercial and residential use.

Which is better for transmission AC or DC?

Transmitting DC power over a long distance is inefficient. Thus AC supply is a far more efficient to transmit power. According to Siemens it's quite the opposite: Whenever power has to be transmitted over long distances, DC transmission is the most economical solution compared to high-voltage AC.

Is AC or DC better for long distance transmission?

“If the transmission line route is longer than about 300 miles, DC is a better option because AC lines have more line losses than DC for bulk power transfer.”

Which is the main advantages of AC transmission system over DC transmission system?

A.C. motors are cheaper and simpler in construction than the d.c. motors. The switchgear (e.g. switches, circuit breakers, etc.) for a.c. the system is cheaper than the d.c. system. A.C. can be easily converted into d.c. by rectifiers.

Which is an advantage of AC over DC for transmission?

AC is less expensive and easy to generate than DC. The distance covered by AC is more than that of the DC. The power loss during transmission in AC is less when compared to DC.

Which of the following is the main advantages of AC transmission system over DC transmission system Mcq?

The AC system has the following advantages over DC System: The power can be generated at high voltages. The maintenance of the AC system is easy and cheaper. The AC voltage can be stepped up or stepped down by transformers with ease and efficiency.
