'single line diagram' or ' one line diagram' is basically a first step in planning substation layout providing the information about switching and protection arrangement required including the incoming lines and outgoing feeders.

for USA, Canada and other countries running a 60 Hz supply service.A 11kV single phase line is one phase of a three phase system. The three phase system voltage is found by multiplying 11kV x 1.73. The three phase primary system voltage is 19kV. A transformer with a 11 kV primary can have a secondary of 115/230 depending on the internal connections in the transformer's case.For the UK11 kV is the standard three-phase h.v. distribution voltage in the UK, where it is a line voltage (i.e. it is the voltage measured between any pair of the three line conductors). A single-phase distribution transformer is connected between any two lines, so 'single-phase 11-kV' is simply a connection made between any two lines of an 11-kV three-phase system.As the primary windings of three-phase 11-kV distribution transformers are delta (3-wire) connected, the primary phase voltage is numerically equal to the primary line voltage (11 kV).
An electrical power substation is a conversion point between transmission level voltages (such as 138Kv) and distribution level voltages (such as 11Kv). A substation has one or more step-down transformers and serves a regional area such as part of a city or neighborhood. Substations are connected to each other by the transmission ring circuit.A electrical grid station is an interconnection point between two transmission ring circuits, often between two geographic regions. They might have a transformer, depending on the possibly different voltages, so that the voltage levels can be adjusted as needed.The interconnected network of grid stations is called the grid, and may ultimately represent an entire multi-state region. In this configuration, loss of a small section, such as loss of a power station, does not impact the grid as a whole, nor does it impact the more localized neighborhoods, as the grid simply shifts its power flow to compensate, giving the power station operator the opportunity to effect repairs without having a blackout.AnswerA 'grid' station is a substation -i.e. a compound or building containing transformers, circuit breakers, busbar systems, and protection system. The correct term is a 'grid substation', which is simply a substation which is part of the grid system -i.e. the transmission system. Other substations include 'primary substations', which interface the transmission system with the distribution system, and 'distribution substations' which could be as simple as a pole-mounted transformer.
it is depends on the rating of distribution transformer,e.g if there is 100 kva, then it will take 5.25amp.
Physically accommodating the size and number of conductors in the stator of an alternator typically limits it output line voltage to 30 kV. In the UK, for example, alternators' line voltage output are typically either 11 kV or 25 kV. So, assuming your (three-phase) alternator has a terminal line voltage of 11 kV, then a 10 MVA alternator should be able to deliver a line current of: line current = (rated apparent power) / (1.732 x rated line voltage) = 10 000 000 / 1.732 x 11 000 = 525 A
A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.

The number 11 has 0 lines of symmetry. A line of symmetry is a line that divides an object into two equal halves that are mirror images of each other. Since the number 11 is a single digit number with no reflective symmetry, it does not have any lines of symmetry.
