Best Answer

For a given load, the higher the supply voltage, the lower the resulting load current. So high voltages are essential for electricity transmission, in order to avoid enormous voltage drops, a need for conductors for huge cross-sectional areas, and to reduce line losses. Actual transmission sytem voltages are determined by the electricity-supply standards used in the country in which you live.

What is maximum transmission voltage in Kerala?

India's is 765 kV.


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'.


How much dc voltage to be applied for test equivalent to 5 kv ac?

5 kV ac means 5 kV rms, which represents a peak voltage of 5 x sqrt (2) kV, or 7.07 kV. So the dc test should provide 7070 volts.


Why you transfer voltage is 11kv33kv66kv?

All sinusoidal AC voltages are multiples of 1.1. This is due to the form factor, which is the ratio of the quadratic mean value of the voltage with the average voltage, which is pi/2√2=1.1 (approximately). It also provides the most economic means of constructing step up/down transformers.AnswerIn the UK, 33 kV (along with 66 kV) is considered to be a primary distribution voltage level, whereas 11 kV is secondary distribution voltage level. Incidentally, the correct symbol for 'kilovolt' is 'kV', not 'kv'.


What is a 132 kv substation?

132kV substation is part of transmission and distribution of power in which the transmission voltage is 132kV. The substation is for stepping down or stepping up of the voltages to the required voltage. the substation also serves as a place where the transmission lines can be isolated, controlled and monitored. The substation consists of different equipment that is used to regulate, monitor and distribute the required power.Another AnswerIn the UK, 132 kV voltages are considered to be the lowest transmission voltages. Other transmission voltages are 275 kV and 400 kV. A '132-kV substation' is normally one in which this voltage is stepped down to a primary distribution voltage, usually 33 kV but, sometimes, 66 kV. As the previous answer points out, substations contain transformers, switchgear, busbars, and protection equipment.

What is the line voltage of a 230000 kv transmission line?

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'.

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)


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.
