Electrical generation at higher voltages would have to have higher insulation between the windings of the generator. This would become physically impossible as the size of the generator would become so large that is would become inefficient. Voltages are generated at lower voltages where the insulation factor between windings is much lower. This low voltage is then transformed into a higher voltage for transmission to other locals.

What is a transmission lines?
An AC transmission line is typically a set of three wires that transports electricity over great distances at potentials exceeding 115,000 Volts. A common intrastate transmission line voltage is 230,000 Volts (230 kV), and interstate lines are normally rated 500,000 Volts (500 kV). When it is desired to transport electricity to a non synchronized area -- like Texas, DC transmission lines are used instead.
What do you mean by the Kv or Mv rating of an insulator?
The Kv marking is how many Kilavolts of electricity the insulator will take. Likewise the Mv is megavolts the rating
Why is the primary of a transformer 11kv?
It isn't necessarily the case. In the UK electricity distribution system, you have 33/11-kV step-down tranformers (where 11 kV is the secondary side) or 11-kV/400-230-V step-up transformers (where 11 kV is the primary side).
What power is required for a radiographic exposure at 76 kV 500 mA?
To calculate the power required for a radiographic exposure at 76 kV and 500 mA, you can use the formula: Power (P) = Voltage (V) × Current (I). Here, P = 76 kV × 500 mA = 76,000 volts × 0.5 amps = 38,000 watts, or 38 kW. Therefore, the power required for the radiographic exposure is 38 kW.
How 33kv power converts into 440volts?
33 kV (not 'kv'!) is the standard primary-distribution voltage used in the UK's electricity supply system. Low voltage (400/230 V -not 440 V) is normally provided by transformers supplied from the 11-kV system, not the 33-kV system.
How many days will it take to produce 500mega watts of electricity?
The time it takes to produce 500 megawatts of electricity depends on the power generation capacity of the plant. If the plant has a capacity of 100 megawatts, it would take 5 days to produce 500 megawatts.
What do a chemical engineer do in a electricity generation plant?
he simply improves the electricity generation process efficiency.
How many watts in 500 kv?
To convert kilovolts (kV) to watts (W), you need to know the current in amperes (A) as well. The relationship is given by the formula: Power (W) = Voltage (V) × Current (A). Therefore, without the current value, you cannot directly convert 500 kV to watts. If you have the current, you can calculate the power by multiplying 500,000 volts by the current in amperes.
Why the generation voltage is 11kv not 10kv?
Alternator output voltages are typically restricted to around 25 kV to limit their physical size and the centrifugal forces to which they are subjected. In the UK, this voltage is then typically raised to 400 kV for transmission.The voltages to which you are referring to are typical of the voltages used in the UK's high-voltage distribution system. 'Grid' substations typically transform transmission voltages of 132 kV down to 33 kV (or, less commonly, 66 kV), and 'primary' substations then transform distribution voltages of 33 kV down to 11 kV.
What is the voltage of the Nigerian power grid?
In order to transmit electricity efficiently, high voltages are used. This high-voltage electricity is then converted to low-voltage electricity at electricity substations (transformers). I'm not sure whether you want to know the transmission voltage or the voltage that comes out of wall sockets.Transmission voltageThe national grid in the UK runs on mainly 400kV AC system with an HVDC system, that runs on 400kV too, across the English Channel.Other voltages in use are 275 kV and 132kV although these are not really classified as transmission voltages.End-user voltageIf you use electricity in the UK, the nominal voltage at the wall socket is 230V. (This is the RMS voltage, which means if you are running something like a lightbulb, heater or kettle it's equivalent to 230V DC. The peak voltage is this multiplied by the square root of 2.)Additional AnswerUK transmission voltages are 400 kV and 275 kV; distribution voltages are 132 kV, 66 kV, 33 kV, and 11 kV.
