Ques:- Why Power generation in India is at 50Hz while in Americaits 60Hz so is there any advantage/Disadvantage of this ??
Asked In :-
southeastern railway, paharpur cooling towers,
Right Answer:
Power generation in India is at 50Hz primarily due to historical decisions and standardization influenced by European practices, while the U.S. adopted 60Hz. The advantages of 60Hz include slightly more efficient power transmission and better performance for some electrical devices, while 50Hz systems can be more efficient for large generators and transformers. However, the difference in frequency can lead to compatibility issues between devices designed for different systems.
