Pu stands for per unit and this will be used in single line diagram of power distribution and it is like a huge electrical circuit with no of components generators, transformers, loads with different ratings in MVA and KV. Those values are called as pu values. Operation carried out in Thermal power stations? The water is obtained in the boiler and the coal is burnt so that steam is obtained this steam is allowed to hit the turbine , the turbine which is coupled with the generator generates the electricity. Why link is provided in neutral of an ac circuit and fuse in phase of ac circuit? Link is provided at a Neutral common point in the circuit from which various connection are taken for the individual control circuit and so it is given in a link form to withstand high Amps.

Both generator and alternator work on the same principle they convert mechanical energy into electrical energy. An RLC circuit carries an electrical circuit consisting of a resistor R and inductor L and a capacitor C , connected in parallel or series. This circuit is called a second order circuit as any voltage or current in the circuit can be described by a second order differential equation. Wire is sized by American Wire Gauge system. Your installation of conductors will depend on a few factors like gauge of the wire, wire capacity, etc.
