An over excited synchronous motor running on no load is known as synchronous condenser. It is used to improve the power factor of the system.

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.

Electrical Power System Interview Questions & Answers

Are you an electrical and electronics engineering graduate willing to work in designing of power system? Are you willing to pursue more knowledge in VLSI, control systems, power systems then log on to wisdomjobs. Electrical Power System is a network of electrical components deployed to supply, transfer, store and use electric power. An example of an electric power system is the grid that provides power to an extended area. It is a network which consists generation, distribution and transmission system. It is the subfield of electrical engineering that deals in preventing damage such as overheating of generators and motors, to reduce transmission losses and to maintain the ability of system to withstand and prevent voltage collapse.

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?

Power System Interview Questions

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.

Power System Interview Question and Answers

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.

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.

Дэвид Беккер смотрел на экран прямо перед. У него кружилась голова, и он едва отдавал себе отчет в происходящем.

Power System Interview Question and Answers

В бомбах было разное топливо. В одной урановое, в другой плутониевое. Это два разных элемента. Люди на подиуме перешептывались. - Уран и плутоний! - воскликнул Джабба, и в его голосе впервые послышались нотки надежды.  - Нам нужно установить разницу между этими элементами.  - Он повернулся к бригаде своих помощников.

 Коммандер, - возразила она, - Танкадо отлично понимал, что АНБ может найти его переписку в Интернете, он никогда не стал бы доверять секреты электронной почте.

 И что же, - спросила Мидж, - это и есть искомый ключ. - Наверняка, - объявил Бринкерхофф. Фонтейн молча обдумывал информацию.

Вы сейчас же отпустите мисс Флетчер, или я вызову службу безопасности и засажу вас в тюрьму до конца ваших дней. - Вы этого не сделаете, - как ни в чем не бывало сказал Хейл.  - Вызов агентов безопасности разрушит все ваши планы. Я им все расскажу.
