Why 230v 50hz in india

Corona Losses also decrease when the frequency of the system decreases. So that 50 Hz power system have less corona losses. Much of Southern California operated on 50 Hz and did not completely change the frequency of their generators and customer equipment to 60 Hz until around Some projects by the Au Sable Electric Company used 30 Hz at transmission voltages up to , volts in In Mexico, areas operating on 50 Hz grid were converted during the s, uniting the country under 60 Hz.

Westinghouse Electric decided to standardize on a lower frequency to permit operation of both electric lighting and induction motors on the same generating system. Although 50 Hz was suitable for both, in Westinghouse considered that existing arc-lighting equipment operated slightly better on 60 Hz, and so that frequency was chosen.

Frequencies much below 50 Hz gave a noticeable flicker of arc or incandescent lighting. In General Electric Corporation, which was affiliated with AEG in Germany, built a generating project at Mill Creek, California using 50 Hz, but changed to 60 Hz a year later to maintain market share with the Westinghouse standard.

Note : Us decided to change their supply system, but they dropped their plan, because of large home appliances works in 60 Hz, if you apply 50 Hz, it does not work well. Is This Answer Correct? Where as the High voltage transfer more power with same loss in the line when compared with a Low voltage line Is This Answer Correct?

More Electrical Engineering Interview Questions. Plz generalized it The countries like US is using 60Hz. So that all the appliences that use electricity require to maintain standards of 60Hz. The major harm of 50Hz is that the power supply with can harmful to human. But the 60Hz supply with less voltage has less harmful for human list. With best regards Dinesh Sood. Points: 5. Tesla decided that 60 Hz was the right frequency for AC power distribution,later some British scientist decided that it should be 50 Hz.

But we could not find the superior one amongst the both as they both have advantages and disadvantages over places New posts.

Thread starter vikramc Start date Feb 20, Status Not open for further replies. I wonder, on what factors Voltage level is determined.

The cost of copper, the cost of insulation, the cost of wasted power in the line drop. This tradeoff would not be the same today with the high cost of energy, but once something becomes standard there is no way to change it. VVV Advanced Member level 5. Initially many countries had V, since it was considered safer for humans.
