In summary, the conversation discusses the pros and cons of using 50 Hz and 60 Hz AC systems and which one is better. It is noted that 50 Hz is less efficient in lower frequency and may require slightly larger transformers. The decision to use one frequency over the other is often based on cost and there may be a shift towards a multi-voltage DC distribution system in the future.

What are the merits and demerits of 50 Hz and 60 Hz AC system? Which one is better?

  • #2
Transformers need to be a little bigger for 50Hz because it is less efficient in lower frequency.
 
  • #4
Probably the relative merits of one vs the other are not enough to justify the cost of anyone changing, so they will stay different.
 
  • #5
They will probably stay unchanged until a multi-voltage DC distribution system can be made to work efficiently.
That may not be too far in the future. There are not a vast number of loads that couldn't be run on DC - at least there wouldn't be if the appropriate technology was already available for the distribution system. Just think - multiphase induction motors with the speed controlled by the frequency of the supply. (That's not BS, is it?)
 

FAQ: Merits and Demerits of 50HZ and 60HZ AC system

What is the difference between 50HZ and 60HZ AC system?

The main difference between 50HZ and 60HZ AC system is the frequency of the alternating current. While the 50HZ system has a frequency of 50 cycles per second, the 60HZ system has a frequency of 60 cycles per second.

What are the merits of using a 50HZ AC system?

Some of the merits of using a 50HZ AC system include lower power losses, better voltage regulation, and lower cost of equipment. This system also allows for longer transmission distances and is more suitable for industrial applications.

What are the demerits of using a 50HZ AC system?

One of the main demerits of using a 50HZ AC system is that it is less efficient for appliances that require high power such as air conditioners and refrigerators. It also requires larger and heavier transformers and power lines, which can be costly.

What are the merits of using a 60HZ AC system?

The main advantage of using a 60HZ AC system is its ability to power appliances that require high power, making it suitable for residential and commercial use. It also allows for smaller and lighter equipment and has better motor performance.

What are the demerits of using a 60HZ AC system?

One of the main demerits of using a 60HZ AC system is its higher cost compared to a 50HZ system. It also has lower voltage regulation and is not suitable for long-distance transmission. Additionally, it can cause electromagnetic interference with electronic devices.
