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.
Why Indian power system in multiples of 11kv?
Multiples of 11 kV are used in many countries. The idea is to deliver a round number of volts so you add on 10% to allow for line losses. So 10 kV becomes 11 kV. In practice lines are operated without a 10% voltage drop now because it represents an unacceptable waste of energy, but we have stuck with 11 kV etc. Common supply voltages used for area distribution are 6.6 kV, 11 kV, 33 kV, 66 kV and 132 kV.
Principle of high kV technique and application in radiograph?
High kv techinque is a technique in which high kv and low ma is used.
What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
What is the distribution voltage in electricity transmission?
Every conductor (in this case, the transmission line) has a finite resistance. so for example let us say it has a resistance of 1 ohm over a distance of 1 km. then, if the current through the conductor is say 100 Amperes, you will have a voltage drop of 100 volts across a length of 1 km. So, a line carrying 100 Amps at 25 kV will have an effective voltage of 24.9 kV
Why railway use 25 KV AC supply system?
It is universal, economical, and efficient.
Which phase line used in raiway system?
25 kV single phase 50 Hz is common in railway systems in the UK.
What is Section Insulator in the context of 25 KV Railway Electrification?
Use for seperation and insulating
Why 25 kv AC used in electric traction?
It is economical and universal.
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.
What is high voltage in marine system?
In the marine system, what is considered high voltages are 3.3 kV, 6.6 kV, and 11 kV. The low voltages, on the other hand, are below 1 kV.

Why do you represent the voltages ranges in terms of 11kilo Volt in power system?
It used to be a convention to add 10% to allow for transmission losses, so the voltages were always described as 11 kV, 33 kV, 66 kV and 132 kV. Later standards in the UK grid are 275 kV, which is a multiple of 11, and 400 kV which is not.

Why electric power generate at 11 kv?
In the UK, 11-kV power lines are part of the distributionsystem, not the transmission system. The system is split as follows:transmission-system voltages: 400 kV, 275 kV, and 132 kV.primary-distribution system voltages: 66 kV and 33 kV.secondary-distribution system voltages: 11 kV and 400/230 V
What happens if 80 kv used for 6.6 kv?
If you are asking what would happen if you applied 80 kV to a system designed for 6.6 kV, then the answer is that the insulation would break down, and a short circuit fault would occur either between conductors, or between conductors and earth (ground) or, possibly, both!
What is the function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
