What are the advantages of generating alternating Voltage for transmission?
Wiki User

The main advantage is that it's very easy to step alternating current up or down in voltage by the use of a transformer. High voltage is preferred for long distance transmission because it cuts transmission loss.

When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
What are the advantages of High Voltage DC transmission over High Voltage AC transmission system?
A few, at least. There are probably more. First, since the frequency is zero, reactive losses due to cable inductance are eliminated. Next, possible health risks due to alternating magnetic fields are reduced. Also, the non-trivial problem of syncronizing two power grids is eliminated. The DC is syncronously converted back to AC at the receiving end's phase and frequency, without regard to the generating end. Another possible benefit (from my point of view at least) is that HVDC systems are, to my knowledge, almost always run underground, eliminating unsightly transmission towers and lines.
Why is alternating current low voltage?
Alternating current is not necessairly low voltage, on the controrary AC is more oftenly used for when high voltage is needed. Most power distribution systems (extremely high voltages) use AC because AC is easier to transform to high voltages (using the aptly named transformer). High voltage is needed for power distribution to decreases losses due to transmission.
What is the highest generating voltage in India?
33 kv.
What does a transformer do to a voltage in a power line?
A transformer is used to step up (increase) or step down (decrease) an alternating voltage with very little loss of energy.
What is electric current from the generating plant?
It is alternating current (AC). AC is used because it is easy to transform the voltage up for transmission over long distances, and down again for consumers.
Is it true that the current supply from electric power generating plants is an alternating current?
Yes, it is true that current supply from generating plants is an alternating current. There is no success found in bulk power generation of direct current ( D.C. ) in a power plant. But yes it is possible to transmit the power in the form of direct current ( High Voltage Direct Current Transmission-HVDC Transmission ) that possible after converting the generated alternating current into direct current with the help of high range converters.
Why do electric company generators produce alternating current?
Because alternating current can be run through a transformer to step up or down the voltage. High voltage current incurs lower losses in transmission.
Why does alternating current alternate its direction?
The generators at the power station are built to deliver voltage/current with alternating characteristics, and this is preserved all the way from the generating station to your house. It's completely intentional, because AC is much easier to handle, distribute, and make the conversions between long-distance and short-distance transmission that need to happen along the way.
How do you derive alternating current from car alternator?
The car's alternator is a three phase generating system. Inside the alternator is a three phase full wave diode bridge that changes the AC generated voltage to a DC voltage.
Why is the alternating current voltage increased?
In order to be transmitted long distances, voltage is raised. At the destination, voltage is lowered again to be used. This permits transmission for several miles, which wold not be possible at lower voltages.
Explain the transmission and distribution of electricity from the generation station to the consumer?
transmission and distribution of electricity are the way of regulate voltage to the minimum rate in which can be benefit to the consumers. From generating station , voltage generated is up 16/25kv which step up upto 330kv this generating voltage now step down in the transmission station through the step down transformer which is 132kv this voltage now transmitting to distribution station where voltage now step down to 33kv, this 33kv now stepdown to 415v for three line and 240/220v for a line for the uses of consumers.
What is the name of the component that is used to increase or decrease alternating voltage?
A transformer is used to increase or decrease alternating voltage.
When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
When the voltage of the electric current produced by a generating plant is lower than the voltage of the current carried by transmission lines?
Yes, that's because the voltage output of an alternator is restricted by the number of windings that can be slotted into its armature, restricting its output voltage to just 25-30 kV, which is far too low for transmission purposes.
