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.
+ and - voltages not connected to earth
In the UK, 11-kV power lines are part of the distributionsystem, not the transmission system. The system is split as follows:transmission-system voltages: 400 kV, 275 kV, and 132 kV.primary-distribution system voltages: 66 kV and 33 kV.secondary-distribution system voltages: 11 kV and 400/230 V
A mountain system is an area of interconnected mountain ranges. The mountain system has a series of ranges linked together by geological features.
In the marine system, what is considered high voltages are 3.3 kV, 6.6 kV, and 11 kV. The low voltages, on the other hand, are below 1 kV.
The terms 'phase voltages' and 'phase currents' are used in three-phase alternating-current systems, to distinguish them between 'line voltages' and 'line currents'.In a three-phase system, the generator has three coils which generate voltages that are displaced from each other by 120 electrical degrees. The generator is then connected to the load using three conductors, called line conductors. The generator's three coils are described as 'phases', and the generated voltages are called 'phase voltages', while the currents flowing in them are called 'phase currents'. The voltages between the line conductors are called 'line voltages' and the currents flowing through the line conductors are called 'line currents'.Similarly, the loads themselves represent 'phases', and the voltages appearing across the loads are called 'phase voltages' and the load currents are called 'phase currents'.Depending on the configuration of the phases (they can be connected in 'delta' or in 'star'), the line voltages either equal the phase voltages or are 1.732 times larger than the phase voltages.
A two-phase system is archaic and you are unlikely to find it in use anywhere these days, so it is mainly of historical interest. A two-phase, three-wire system, consists of two phase voltages, displaced from each other by 90 electrical degrees, and a phase voltage which is 1.414 x phase voltage.A three-phase system consists of three phase voltages which are displaced from each other by 120 electrical degrees. In the case of a three-phase, three-wire, system, the line voltages are numerically equal to the phase voltages; in the case of a three-phase, four-wire, system, the line voltages are 1.732 x phase voltage.
For a three-phase, three-wire, system there are three conductors called 'line conductors', and there is a voltage between any pair of line conductors, so there are three voltages.For a three-phase, four-wire, system there are four conductors: three 'line conductors' and a 'neutral' conductor. So there are three line voltages (voltages between lines) and three phase voltages (voltages between any line conductor and a neutral conductor).
The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts.For more information see the Related Link shown below.
The Himalayas have parallel ranges of mountains.
The Three mountain ranges are: -Cascades -Alaska and Aleutian Ranges -Coast Ranges - On the coastline of the Pacific is the Sierra Nevada of California
A three-phase, three-wire, system is obtained from a delta-connected source. A three-phase, four-wire, system is obtained from a star-connected source.A three-phase three-wire system comprises three conductors, called line conductors. The voltages measured between any pair of line conductors is called are called line voltages and, numerically, they are identical to phase voltages.A three-phase four-wire system comprises three line conductors, and a neutral conductor. The voltages measured between any pair of line conductors are called line voltages and the voltages measured between any line conductor and the neutral conductor are called phase voltages. The value of a line voltage is 1.732 times the value of a phase voltage.
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.

The mountain ranges that go along the Pacific coast are the Pacific Mountain System and the Pacific Coast Ranges. The peak of the Pacific Coast Ranges is Mount Logan.
Yes, a 3 wire system can create neutral voltages due to harmonic distortion. Neutral voltages can also be caused by load imbalance between the two hots. It is normal for neutral to have a voltage differential relative to ground. Neutral is, after all, a current carrying conductor. In a well balanced system, however, there is little (theoretically zero) current in neutral.

A transmission system is that part of the electricity supply system that transfers bulk energy, at very high voltages, from centres of generation (often located in remote locations) to centres of load (e.g. large towns). From that point onwards, it is known as the distribution system, which operates at voltages below transmission-level voltages.All transmission/distribution systems operate are three-phase systems because, for a given load, a three-phase system uses less copper than single phase, and is therefore more economical.
It depends on the type of three-phase system. If it's a three-wire system, then the phase voltage is numerically equal to the line voltage. If it's a four-wire system, then the phase voltage is numerically equal to the line voltage divided by 1.732 -in your example, this works out to be 5.77 V.
A two-phase system is an archaic system, in which two voltages are generated ninety electrical degrees apart. For a two-phase, three-wire, system the line voltage is 1.414 times the value of the phase voltage. This system has been long replaced by a three-phase system, in which three voltages are generated 120 electrical degrees apart. You cannot, therefore, convert a three-phase system to a two-phase system.
The years represent planets going around the sun.
It has to with the fact that when voltages go higher the current goes lower. The lower the current a device draws, the smaller the wire size needs to be to carry that current.
A number system used to represent any number by a 1 or a zero is a binary system or a base 2 number system.
