transmission and distribution interview questions and answers pdf
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.
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.

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.
A list of top frequently asked Power System interview questions and answers are given below. 1) What is the Power plant or Power Station? The generation.
Power System Interview 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.
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.

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.
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.
У нас много денег - какая разница, кто из нас их получает. Но это была чужая епархия. В конце концов ей пришлось смириться. Когда они в ту ночь отправились спать, она старалась радоваться с ним вместе, но что-то в глубине души говорило ей: все это кончится плохо. Она оказалась права, но никогда не подозревала насколько.
