How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
What is peak voltage value of 3 phase?
The same as in single phase with the same RMS voltage.
Why in a star connection phase voltage is 1.73times of line voltage?
It isn't. It's the other way around. The line voltage is 1.732 times the phase voltage. The figure results when you vectorially add the relevant phase voltages.
Is transmission line voltage phase to phase?
Yes usually it would be phase to phase voltage because most transmission lines are set up in a delta configuration. This means that there is no neutral conductor to use as a reference. So any voltage would be measured with reference to another phase.CommentLet's get the terminology correct. The voltages between the three 'hot' lines of a three-phase, three- or four-wire, system are called 'line voltages' even though, in the case of a delta-connected system, they are numerically-equal to the corresponding phase voltages. Therefore, we call the conductors 'line conductors', not 'phase conductors'.There is simply no such thing as a 'phase-to-phase' voltage. Just think about it; you can only measure a voltage acrossan individual phase, so how can you possible measure a voltage 'phase-to-phase' -I mean, where would you place a voltmeter to do that?For a delta system, the line voltage (or line-to-line) voltage is numerically equal to the phase voltage (notphase-to-phase). For a star (or 'wye') system, the line voltage is equal to 1.73 x the phase voltage.

What is 11 kV single phase?
for USA, Canada and other countries running a 60 Hz supply service.A 11kV single phase line is one phase of a three phase system. The three phase system voltage is found by multiplying 11kV x 1.73. The three phase primary system voltage is 19kV. A transformer with a 11 kV primary can have a secondary of 115/230 depending on the internal connections in the transformer's case.For the UK11 kV is the standard three-phase h.v. distribution voltage in the UK, where it is a line voltage (i.e. it is the voltage measured between any pair of the three line conductors). A single-phase distribution transformer is connected between any two lines, so 'single-phase 11-kV' is simply a connection made between any two lines of an 11-kV three-phase system.As the primary windings of three-phase 11-kV distribution transformers are delta (3-wire) connected, the primary phase voltage is numerically equal to the primary line voltage (11 kV).
Why is high voltage from 11kv onwards?
To be precise this kind of hi voltage is called distribution by power company. 11kv 16 kv that type of voltage. however transmission can be in the range of 5ookv. And you can see at tower from interstates lines
How many voltage between phase and earth?
Depends on country.
How can measure the voltage only seeing the insulators in a high voltage transmission lines?
i think 11kv per insulator
What is the total of a phase to earth voltage on 11000 volts?
An 11,000 volt three-phase supply has a voltage of 6351 from live to neutral, when there is a neutral wire.
Why do you have voltage to ground but not voltage phase to phase?
There is phase to phase voltage in 3 phase system.AnswerYou don't get voltage 'phase-to-phase'; it's 'line-to-line'!
How do you calculate 3 phase earth fault loop?
You can't have a three phase earth fault, you can have a phase to phase or a phase to earth fault. If you want the potential phase to earth fault current it will be your voltage times your impedance. If you want the phase to phase potential fault current then you should just double the above result.
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
What will be the resultant voltage if the two phase voltage having no phase difference?
If two phase voltages are the same voltage and the same phase angle, the the resultant voltage will be twice the voltage.
Voltage across Neutral and earth for a 3 phase auto transformer?
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
