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?

The generation, distribution, and transmission system together constitute a network called as Power plant. The power plant uses the form of energy such as coal, diesel and converts it into electrical energy. An example of the power system is a grid that supplies power to the other system. The protection is provided in the system to protect each and every element of the power system. If any fault occurs in the system then the relays associated with it trip all the circuit breaker so that the faulty element gets removed from the power system. This Security provided to the system is called the 'Zone of protection'.
Electrical Power System Interview Questions & Answers
Answer: Galloping in transmission line conductors arises generally due to symmetrical layers of ice formation. Answer: The transmission line is not fully stretched but it is allowed to sag down. The difference in levels between point of support and the lowest point on the conductor is called sag. On what basis is the insulation level of a kv, EHV overhead transmission line decided? Answer: At transmission line voltages up to kv, the insulation level is dictated by the requirement of protection against lightning. In EHV, switching surges cause higher over voltages than lightning and are therefore mainly responsible for insulation level decision.

The Power system is a network which consists of the components used in generation, distribution and transmission systems. The power system is used to produce electrical energy from coal and diesel. It has devices that are connected to the system like motor, circuit breaker, synchronous generator, transformer, conductor, etc. P-V curve or indicator diagram represent the corresponding change in pressure and volume in a system. This curve is very useful in many processes like cardiovascular physiology, thermodynamics and respiratory physiology.
