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.
i think 11kv per insulator
Its just a matter of standard. In my area, for instance, we use 13.2 KV for distribution lines, and 69 KV / 138 KV for transmission lines.
Yes. But,circuit breaker are usually rated in terms of current they can interrupt,not the voltage.
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
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
i think 11kv per insulator
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
High voltage reduces the amount of energy wasted in transmission lines.
Its just a matter of standard. In my area, for instance, we use 13.2 KV for distribution lines, and 69 KV / 138 KV for transmission lines.
6350.8 volts AC rms. The phase to earth voltage is ( square root(3) ) x lower than the phase-phase voltage on a 3 phase system.
Yes. But,circuit breaker are usually rated in terms of current they can interrupt,not the voltage.

The generation voltage of vtps is a variation of many different principles.

Depends on the sub station. It could be 11KV, 33KV, 66KV,110KV, 220KV, 400 KV etc
