What are the standard voltages for transmission?
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.
Why you use 33kv for power transmission?
Power loss during power transmission is predominantly due to the current drawn, which heats the wires. Power dissipated is current x voltage and voltage is current x resistance, so in any wire with fixed resistance the power loss is proportional to the square of the current flowing. The higher the voltage you use to transmit the power down the distribution network the lower is the current, hence power is distributed at the highest voltage that is practical, then the voltage is dropped to the domestic level at the destination sub-station or by a transformer on the power line pole. Major distribution systems operate at over 100 kV, with regional ones at lower voltage.Additional Answer33 kV (not 'kv'!) is the primary distribution voltage, not a transmission voltage, used in the UK. Other distribution voltages are 66 kV (not very common) and 11 kV. Transmission systems operate at 400 kV and 275 kV.
Why generated voltage of synchronous generator is 13.7KV?
The voltage output of a generator is set by design and system requirements. Nothing is special about 13.7 KV. In fact, most generators that I am familiar with in utility power applications are 24 KV, with the voltage being stepped up with a transformer to transmission level voltages.Perhaps the question refers to distribution voltages. One standard is 13.2 KV, with the transmission voltage being 69 KV, 138 KV, or 345 KV. Again, it depends on system requirements.
Minimum ground clearance for 765 kv Transmission Line?
Ground clearance132 kv - 6100 mm220 kv - 7015mm400 kv - 8840mm765 kv - 15000mm
Where is the highest transmission voltage in India?
the highest transmission volatage in India is 765kV ac. The highest voltage in the case of DC transmission is +/- 600 kV.
What is the induced voltage on a deenergized ungrounded circuit 60 feet from a 230000 volt circuit?
This question has not enough information for an answer. Is the 230 kV line overhead or underground? The voltage induced in a passive wire also depends on the amount of current in the high-power line.
What is voltage in rotor of 11 KV AC generator?
Star (or 'wye') connected alternators have a phase voltage of 6.35 kV, and a line voltage of 11 kV. Incidentally, it's 'kV', not 'KV'.

What is maximum transmission voltage in Russia?
220 kV
What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
How do you tell the difference from 13.2 kv power line to 4.8 kv power line?
The higher-voltage line will have longer insulators and the line conductors will be further apart. And the symbol for kilovolt is 'kV', not 'kv'.

Why only 11kv is used in power systems transmission line?
It isn't. In the UK, transmission and distribution voltages are 400 kV, 275 kV, 132 kV, 66 kV, 33kV, and 11 kV.
Why transmission voltage always be multiple of 11?
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)

What is the Phase to phase voltage of 66KV earthed cable?
Nominal transmission and distribution voltages are line voltages. So '66 kV' is a line-to-line voltage. Note that there is no such thing as a 'phase-to-phase' voltage -the correct term is 'line-to-line'. Using the term, 'phase-to-phase', indicates a lack of understanding of a.c., which is not uncommon! Incidentally, the symbol is 'kV', not 'KV'.
What is maximum transmission voltage in Kerala?
India's is 765 kV.
