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.

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.”

Why cant DC spread long distances?

High voltage overcomes voltage drop over long distances. The reason that AC is transmitted instead of DC is that it is much cheaper and easier to boost and reduce AC voltage than DC. In fact, DC has fewer losses in long distance transmission. The longest transmission lines are, in fact, DC; often over a million volts.

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.

What are the advantages of AC system over DC system?

Key Advantages of AC over DC
The AC is simpler to produce than DC. It is also less expensive than DC to generate. The AC systems have higher efficiency than DC such as ac generators. The waste of power is negligible for AC during transmission.

What is the advantage of AC over DC?

Following are the advantages of alternating current over direct current: 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.

Why is AC current preferred over DC?

AC voltage is preferred over DC voltage because it is economical and less complicated. AC voltage is more efficient than DC since minimum energy loss happens during transmission.

What is the main advantage of AC power transmission over DC power transmission over long distance?

The main advantage of A.C power transmission over D.C power transmission over long distances is AC transmit without much loss of energy. Explanation: In comparison to DC, AC can carry energy over a long distance with little energy loss.

What is the advantage of AC power transmission Mcq?

Why is AC transmission preferred to long distance than DC?

AC is used for long distance power transmission instead of DC because it is more convenient to step up/down voltage for AC than DC.

Why AC transmission is preffered to long distance than DC?

AC is still preferred for general distribution because it is much easier to transform the voltage up or down. High voltage is preferred for long distance transmission because there is less current at high voltage for the same power. There are lower loses in the transmission lines due to lower current.

Can DC be used for long distance transmission?

Whenever power has to be transmitted over long distances, DC transmission is the most economical solution compared to high-voltage AC.

Why dont we use DC in our transmission lines instead?

The answer to why DC current is not used in homes goes back to the inherent characteristics of direct currents and their weaknesses compared to Alternating Currents (AC). In fact, AC currents can be easily transmitted over long distances without much loss. They are also safer in direct touch at an equal voltage.

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.

What are the advantages and disadvantage of AC over DC?

(i) The generation of AC is cheaper than that of DC. (ii) When AC is supplied at higher voltages, the transmission losses are small compared to DC transmission. (iii) AC can easily be converted into DC with the help of rectifiers.

What is the single greatest advantage that AC has over DC electricity?

The major advantage that AC electricity has over DC electricity is that AC voltages can be readily transformed to higher or lower voltage levels, while it is difficult to do that with DC voltages.

What are the advantage and disadvantage of AC over DC?

(i) The generation of AC is cheaper than that of DC. (ii) When AC is supplied at higher voltages, the transmission losses are small compared to DC transmission. (iii) AC can easily be converted into DC with the help of rectifiers.

What are the advantages of AC over DC Class 12?

Advantages of ac over dc:
AC can be transmitted using step up transformers but direct current or dc can not be transmitted by this method. The ac is easy to generate than dc. It is cheaper to generate ac than dc. The ac generators have higher efficiency than dc.

Why is AC voltage is preferred over DC voltage give two reasons?

(i) AC can be transmitted with much lower energy losses as compared to dc. (ii) AC voltage can be adjusted (stepped-up or stepped down) as per requirement. (iii) AC current in a circuit can be controlled using (almost) wattless devices like choke coil. (iv) AC is easier to generate.

Why AC supply drives are preferred?

Advantages provided by AC drives include: Reduced power line disturbances, lower power demand on start, controlled acceleration, controlled starting current, adjustable operation speed, and adjustable torque.

What are the advantages of AC transmission system?

Advantages of AC Transmission
The AC voltage can be increased with the help of a step-up transformer or can be decreased using the step-down transformer easily and efficiently. Therefore, the AC transmission permits to transmit the electric power at high voltages and to distribute it at lower voltages.

What are the advantage and disadvantage of AC over DC transmission?

(i) The generation of AC is cheaper than that of DC. (ii) When AC is supplied at higher voltages, the transmission losses are small compared to DC transmission. (iii) AC can easily be converted into DC with the help of rectifiers.

Why is DC not transmitted over long distance?

DC current cannot be transmitted over long distances because of low voltage and high current the transmission lines will burn out and you have to have a substation for every small distance.
