Answer: Booster is low voltage high current series wound DC generator inserted into a DC circuits to add or inject a certain voltage proportional to the circuit current. The main purpose of providing booster in power system is to compensate the voltage drop of feeder.
Booster add voltage to the feeder and compensate the voltage drop. Hence it increase the efficiency and reliability of the system. That is why it is one of the important device of power system.
