300+ TOP POWER SYSTEM LAB VIVA Questions and 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. If any fault occurs in the system then the relays associated with it trip all the circuit breaker so that the faulty element gets removed from the power system. This Security provided to the system is called the 'Zone of protection'. The main work of transmission line and distribution line is to transfer power from one place to another but the difference between transmission and distribution line is based on the factors like the type of phase, the distribution line because the wire for transmission line is thick and for distribution line is thin, the transmission line requires three phase supply for carrying electricity and distribution line requires single phase supply for carrying electricity.

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.
