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 is a Transformer 2. How are Primary and secondary windings of a Transformer connected 3. Name different types of Transformer based on Number of windings 4. Where Transformers are applicable 5.

Name the types of motors used in vacuum cleaners, phonographic appliances, vending machines, refrigerators, rolling mills, lathes, power factor improvement and cranes. Explain the process of commutation in a dc machine. Explain what are inter-poles and why they are required in a dc machine. Define the following terms:- Reliability, Maximum demand, Reserve-generating capacity, Availability operational. Explain the terms real power, apparent power and reactive power for ac circuits and also the units used.

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. Wire is sized by American Wire Gauge system. Your installation of conductors will depend on a few factors like gauge of the wire, wire capacity, etc.

In today post, we will be sharing the frequently asked electrical engineering interview questions and answers related to electrical engineering. Electrical engineering deals with high voltage especially AC above the range of or V. When manufacturers design a transformer, they have no idea which kind of load will be connected to the transformer. The output of real power may vary depending on the power factor. A real transformer has the following losses;. The losses occur due to the current flow through the windings that causes resistive heating of the conductors. There are two types of core or iron losses.
