why AC voltage source are generate as 50 Hz ?
Answers were Sorted based on User's Feedback
Answer / skeeter
Synchronous sources operate according to the equation:
(Hz) = (Poles)*(RPM)/120.
Generation can occur at any frequency that meets this
condition. Every electrical distribution network has its
preferred freqeuncy; North America is predominantly 60 Hz,
while Europe and Asia tend to favor 50 Hz. However, several
other frequencies also exist - ranging from 25 Hz to
several megahertz.

5o Hz is the standard frequency in india, technically the
frequcy produced by the Ac genrater depends on F= Number of
poles*Speed of generator/120 which is equal to 50 HZ for a
4pole 1500 Rpm and running speed of generator is 1500 RPM

Answer / g.oopi
INDIAN STANDED ALL THE LOAD IN 50HZ BASED ON DESING OF
MANUFA... TO ALTERNATOR Ns*p/120 s0 positive cycle &-ve cycle
in 50hz where Ns=1500rpm
| Is This Answer Correct ? | 0 Yes | 0 No |
This is standared in india AC power is produced at 50 hz
frequency out of india it's 80 hz. Due to this sign wave of
current and volatage complete grah.
