## Electrical Machines Interview Questions & Answers

What is the power factor of a transformer at no load? At no load, the power factor of a transformer is very low and lagging, whereas the power factor on load is nearly equal to the power factor of the load, which it is carrying. What is the normal phase difference between the voltage and the no-load current in a transformer? What are the essential parts of a transformer? The essential parts of a transformer are as follows: i. Magnetic circuit consisting of laminated iron core and clamping structure ii.

Frequently asked interview questions with answers under the subjects like electrical machines,Transmission and distribution,Power electronics and some general basic questions. Question Question 1. This arc must be contained, cooled, and extinguished in a controlled way, so that the gap between the contacts can again withstand the voltage in the circuit. What are avoidable questions in an Interview? Tell me about yourself. A wide range of power line communication technologies are needed for different applications, ranging from home automation to Internet access.

In case of motor it produces unidirectional torque. What is the choice of material for the yoke? It is defined as the distance on the periphery of the armature between two coil sides of a coil. Usually, it is expressed in terms of no of slots or degrees electrical. The factor by which there is a reduction in the emf due to short pitching of the coils is called coil span factor. It is defined as the ratio of the resultant emf when coils are short pitched to the resultant emf when coils are full pitched. The factor by which there is a reduction in the emf due to distribution of coils is called distribution factor K d.

## 100+ TOP ELECTRICAL MACHINES LAB VIVA Questions and Answers

Are you an electrical and electronics engineering graduate willing to work in designing and installation of electrical machinery? Are you capable enough to build something amazing in the field of electrical machines then log on to the wisdomjobs. Electrical Machine is a device which converts mechanical energy into electrical energy or vice versa. Electrical machine is a general term for machines using electromagnetic forces such as electric motors, electric generators and others. They provide virtually all electric power of earth.

It is interesting to read your blog post and I am going to share it with my friends. In , the National Association of Electrical Distributors was formed to "establish the electrical distributor as an essential force in the electrical industry and economy," followed by the National Electrical Manufacturer's Association NEMA in Today, the technology is becoming advanced day by day. Those gadgets and electronic devices that were considered impossible a few years ago, have become reality in today's world.

### Electrical Machines Interview Questions

A list of top frequently asked Electrical Machines interview questions and answers are given below. A Single-phase autotransformer is a single winding transformer in which a part of the winding is common to both high-voltage and low-voltage sides. This law states that when we move any current carrying conductor in a magnetic field, then an EMF is induced in it.

Answer: In transformer protection, harmonic restraint feature is incorporated to guard against magnetizing inrush current. What are the conditions for successful parallel operation of single-phase transformers? Answer: The satisfactory and successful operation of transformers connected in parallel on both sides requires that they fulfill the following conditions:. Why the tappings are normally provided on the high voltage winding of a transformer only? Answer: Tapping are normally provided on the high voltage winding of a transformer only because it has larger number of turns, has to handle low currents and is also easily accessible physically. What is the purpose of providing dummy coils in the armature of a dc machine? Answer: The purpose of providing dummy coils in the armature of a dc machine is to provide mechanical balance for the rotor.

Electronics in our lives is like the life support which is supporting the human survival and development. They are now the most integrated part of human being. Starting from small toys to large spaceships, small lighting to large space stations, at all places we have the electronics in various forms with us. Let it be concentrated over the Electric Motors. Electric Motors are the machines that convert electrical energy into the mechanical energy which further is used to drive a vehicle, plant and many more things around us. Here are the types of questions on electric motors which are asked in an interview, question papers and other competitive exams as well.

Интересно. А что по этому поводу думает Энсей Танкадо. - Я ничем не обязан мистеру Танкадо. Он зря мне доверился. Ключ стоит в сотни раз больше того, что он платит мне за его хранение. - Извините, но ваш ключ сам по себе ничего не стоит. Как только Танкадо узнает о том, что вы сделали, он опубликует свою копию, и рынок рухнет.

Для панков? - переспросил бармен, странно посмотрев на Беккера. - Да. Есть ли в Севилье такое место, где тусуются панки. - No lo se, senor. He знаю.

Я беру на себя верхнюю четверть пунктов, вы, Сьюзан, среднюю. Остальные - все, что внизу. Мы ищем различие, выражаемое простым числом. Через несколько секунд всем стало ясно, что эта затея бессмысленна. Числа были огромными, в ряде случаев не совпадали единицы измерения.

И с успехом его выдержал. Ненависть в его сердце уступила место преданности Будде. Еще через четыре месяца Энсей Танкадо приступил к работе в Отделении криптографии Агентства национальной безопасности США.

Конец веревочки. Он набрал номер. - Escortes Belen, - ответил мужчина.

Он боялся ее как огня. Ее мозги работали словно на совсем другом уровне. Она подавляла его своей красотой, и всякий раз, когда он оказывался рядом, язык у него заплетался.

Больно. - Да нет вообще-то. Я грохнулся на землю - такова цена, которую приходится платить добрым самаритянам. Вот запястье в самом деле болит.

Человек, сидевший рядом, посмотрел на него в недоумении: так не принято было вести себя в храме Божьем. - Enferno, - извиняясь, сказал Беккер.  - Я плохо себя чувствую.  - Он знал, что должен буквально вдавиться в пол. И вдруг увидел знакомый силуэт в проходе между скамьями сбоку.
