Transmission voltages are in multiples of 11 to allow for 10% transmission line losses. Therefore, to obtain 100% efficiency, voltages in multiples of 11 are transmitted.
The standard voltage for transmission is about 115 to 1,200 kV (long-distance transmission). The extreme high voltages are measured more than 2,000 kV and it is exists between conductor and ground.Answer for UKThe standard transmission voltages in the UK are 400 kV and 275 kV. Primary distribution voltages are 132 kV and 33 kV, and secondary distribution voltages are 11 kV and 400 V. These are all line voltages -i.e. voltages measured between line conductors.
A: Those voltages are called distribution voltages to differentiate from transmission voltages. And that varies from state to state and locals . Usually around 10kv to 20 kv
Transmission and distribution voltages are normally expressed in terms of line voltages, so the answer is that the figure you quote is a line voltage. Incidentally, do you really mean 230 megavolts for a transmission voltage?? And the symbol of kilovolt is 'kV', not 'kv'.
Low loss transmission of power at high voltages for long distances then the ability to transform down to lower voltages near the point of usage, i.e. substations and pole transformers near residences.
The voltage at the service, such as a customer (your home, for example). This may be contrasted with the transmission, subtransmission, and distribution voltages used to get power from the generator to the customer.
34.5, 69, 115, 161, 230, 345, 500kV are all common transmission (and distribution) voltages. They aren't all multiples of 11.Additional CommentI think that the questioner is British because, in the UK, most transmission and distribution voltages are multiples of 11. These are 11 kV, 33 kV, (66 kV*), and 275 kV. The exception is the highest transmission voltage of 400 kV.(*66 kV is less common these days)

It isn't. In the UK, transmission and distribution voltages are 400 kV, 275 kV, 132 kV, 66 kV, 33kV, and 11 kV.

Low voltages are not 'combined into higher voltages' for transmission! The lower voltage (e.g. the voltage generated at a power station) is applied to the primary winding of a large power transformer, and the required higher transmission voltage then appears across the transformer's secondary winding. The magnitude of the secondary voltage is determined by the turns ratio of the transformer's windings.
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.
They are: 407 and its multiples
11, 22, 33, 44, and 55 are the first five multiples for eleven

The common multiples of 11 and 4 are 88, and 4.
Since both 11 and 13 are prime numbers, the LCM of these 2 number is 11 * 13 = 143. All multiples of 143 are multiples of 11 and 13 as well
