Power System Interview Questions

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 cosine of angle between voltage and the current in an AC circuit is known as power factor. It is a usual practice to attach a word lagging or leading with the numerical value of power factor to signify whether the current lags or leads the voltage.

Circuit breaker performs interruption function only. The detection of fault is made by relay system. In case of circuit breaker, replacement is not required. The difference in level between points of supports and the lowest point on the conductor is called sag.

The phenomenon of violet glow, hissing noise and production of ozone gas in an overhead transmission line is known as corona. By increasing conductor size, the voltage at which corona occurs is raised and hence corona effects are considerably reduced.

By increasing the spacing between conductors, the voltage at which corona occurs is raised and hence corona effects can be eliminated. The rate at which electrical energy is supplied to a consumer is known as tariff. Simple tariff 2. Flat rate tariff 3. Block rate tariff 4. Two-part tariff 5. Maximum demand tariff 6. Power factor tariff 7. Three-part tariff. So supply of electricity can be ensured. They are radioactive in nature.

300+ TOP POWER SYSTEM LAB VIVA Questions and 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 making and breaking currents of three phase ac circuit breakers in power system are in which form?

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. P-V curve designed in the 18th century to understand the efficiency of the engine.

It is a combination of hardware and software. Power factor. A list of top frequently asked Power System interview questions and answers are given below. These selected questions and answers are prepared from Operating Systems Exam point of view and will also help in quick revision to get good marks in Operating Systems Examination. What is an embedded system?


40) How many methods use the load flow solution? The method that uses the load flow analysis is as follows: Gauss-Seidel method using Y bus; Newton-.


Electrical Power System Interview Questions & Answers

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.

Review a list of frequently asked Electrical interview questions for electrical graduates. Internal faults are the faults that occur inside the zone and external faults are the faults that occur outside the zone of protection. Power System Interview Questions.

Power system Analysis Questions and 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. Question 1.

 - Он поднял беретту.  - Ты найдешь терминал Хейла, а я тебя прикрою. Сьюзан была отвратительна даже мысль об. - Разве нельзя дождаться звонка Дэвида о той копии, что была у Танкадо. Стратмор покачал головой. - Чем быстрее мы внесем изменение в программу, тем легче будет все остальное. У нас нет гарантий, что Дэвид найдет вторую копию.

Повернувшись к терминалу Хейла, Сьюзан вдруг уловила странный мускусный запах - очень необычный для Третьего узла. Она подумала, что дело, быть может, в неисправном ионизаторе воздуха. Запах показался ей смутно знакомым, и эта мысль пронзила ее холодом. Сьюзан представила себе Хейла в западне, в окутанной паром ловушке. Может быть, он что-нибудь поджег. Она посмотрела на вентиляционный люк и принюхалась.

Беккер обернулся. Двери оказались прямо перед ним, словно приглашая его принять участие в празднестве, до которого ему не было никакого дела. Внезапно он понял, что входит в собор. ГЛАВА 90 В шифровалке завывали сирены. Стратмор не имел представления о том, сколько времени прошло после ухода Сьюзан.

Говорила Мидж - излагая серию необычайных событий, которые заставили их нарушить неприкосновенность кабинета. - Вирус? - холодно переспросил директор.  - Вы оба думаете, что в нашем компьютере вирус.

Прямо перед ней во всю стену был Дэвид, его лицо с резкими чертами. - Сьюзан, я хочу кое о чем тебя спросить.  - Звук его голоса гулко раздался в комнате оперативного управления, и все тут же замерли, повернувшись к экрану. - Сьюзан Флетчер, выйдете за меня замуж. В комнате зашушукались.

Черные атакующие линии начали исчезать. - Происходит восстановление! - кричал Джабба.  - Все становится на свои места.
