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. Eddy current losses can be minimized by laminating the core and insulating the core from each other with paper or varnish. High-speed alternators are called Turbo Alternators. Because of the high speed of rotation, the diameter of the rotor is reduced, and the axial length is increased.
In this MCQ you can learn and practice Voltage Regulation of Transformer objective quiz questions to test your knowledge on electrical machines In this MCQ you can learn and practice Equivalent Circuit of Transformer objective quiz questions to test your knowledge on electrical machines In this MCQ you can learn and practice Transformer as a Magnetically Coupled Circuit objective quiz questions to test your knowledge on electrical machines However, this would mean one less equation than the number of variables node voltages present in the circuit. A constraint equation can be easily specified given by the magnitude of the ideal voltage source present between the nodes and the respective node voltages. The following example will help clarify this scenario. It takes energy from a battery or some other power source to move electrons to one of the plates and away from the other. Answer : The quantity of total charge that passes through an arbitrary cross-section of a conducting material per unit second is defined as an Ampere. Where, Q is the symbol of charge measured in Coulombs C , I is the current in amperes A and t is the time in seconds s. C Alternating Current?
Electrical Machines 1 Viva Questions and Answers
In this post we had collected some of the most frequently asked electrical machines 1 viva questions with detailed answers. We believe that these FAQs will be useful for your practical exams and interviews as well. Dec] The equivalent circuit is the electrical model of the transformer. For synchronous machines there exists a fixed relationship between number of poles P, frequency f and the speed of the machine. A turning or twisting force about an axis is defined as torque.
And those help us interpret what goes on during NDEs. In fact, some of these patterns are standard and give us a boilerplate code. If you will, your spirit left your body. You need to rest up and let the sedative leave your system. She would have done anything to save it. Materson had coloured slightly and his breathing was raggedy from the mild exertion. We shook hands and I put his age at not much over twenty.
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.

Его жертва не приготовилась к отпору. Хотя, быть может, подумал Халохот, Беккер не видел, как он вошел в башню. Это означало, что на его, Халохота, стороне фактор внезапности, хотя вряд ли он в этом так уж нуждается, у него и так все козыри на руках. Ему на руку была даже конструкция башни: лестница выходила на видовую площадку с юго-западной стороны, и Халохот мог стрелять напрямую с любой точки, не оставляя Беккеру возможности оказаться у него за спиной, В довершение всего Халохот двигался от темноты к свету. Расстрельная камера, мысленно усмехнулся. Халохот оценил расстояние до входа.
