Why frequency in india is 50 hertz

Example: Take a steam power plant which is running with coal and the coal to the steam ratio of the boiler is 4. But the Steam to power ratio is 2. The coal cost is Rs. To avoid this, we have to reduce the auxiliary consumption. Auxiliary consumption can be reduced by reducing losses of the plant. When we increase the frequency of the generation, simultaneously, the output voltage also increases.

Hence the insulation strength to increase the increasing voltage. 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 Tesla later compromised to reduce the voltage to volts for safety reasons.

Meanwhile, the German company AEG started generating electricity and became a virtual monopoly in Europe. They decided to use 50Hz instead of 60Hz to better fit their metric standards, but they kept the voltage at V. They are more costly to make to handle the electrical losses and the extra heat generated at the lower frequency. They then switched over to V for better efficiency in electrical transmission. Great Britain not only switched to V, but they also changed from 60Hz to 50Hz to follow the European lead.

Since many people did not yet have electrical appliances in Europe after the war, the change-over was not that expensive for them. A compromise was made in the U. Certain household appliances such as the electric stove and electric clothes dryer would be powered at V.

The extra 10V was provided at the supply end to account for the transmission line losses. Since then the US has followed the practice of V live wire voltage with respect to the neutral. In European countries, a V line voltage was preferred due to the increased transmission efficiency even though it is more dangerous. The latest emerging technology is the smart grid technology.

This technology aims at integrating control systems with the grid to provide a more detailed information about power demand to the engineers in various regions of the grid.

It also aims at using Artificial Intelligence to solve power system related issues and also automatic rerouting of power from generating station to homes in case of any environmental damage caused to the transmission line. The smart grid also aims at merging renewables such as wind and solar energy to the existing grid. This technology will help in saving this precious resource that all of us take for granted.

Series Tags. Why 50Hz? Lower the frequency, speed of induction motor and generator will be lower. The design of such magnetic machines is such that they are really one or the other. It may work in some cases, but not always. To change between different power supply frequencies will certainly have an effect on efficiency, and may mean de-rating is necessary. There is little real difference between 50 Hz and 60 Hz systems, as long as the equipment is designed appropriately for the frequency.

It is more important to have a standard and stick with it. The more significant difference is that 60 Hz systems usually use V V or thereabouts for the domestic power supply, while 50 Hz systems tend to use V, V etc.

This has the impact that house wiring needs to be twice the cross section for the V system for the same power. However the optimum system is accepted as around V wire size and power required versus safety. It is no big difference between 50 Hz and 60 Hz, nothing is bad or good basically. To obtain optimum performance, motors used for 50 Hz applications should be specifically engineered and manufactured for 50 Hz. Frequently, the delivery of 50 Hz products is such that an alternate course of action, utilizing 60 Hz products, is desirable.

The general guidelines for operating 60 Hz motors on 50 Hz systems relate to the fact that the volts per cycle have to remain constant with any change in frequency. Also, since the motor will operate at only five sixths of 60 Hz speed the output horsepower capability of 50 Hz is limited to a maximum of five sixths of nameplate H. Source: U. Machinery imported into the United States is often rated at an operating frequency of 50 Hz—unless engineered for operation at 60 Hz..

This can be problematic for electric motors.
