Whats Is Voltage Regulation In Generators And Uses Of D.C. Generators

  • Whats Is Voltage Regulation In Generators

Voltage Regulation In Generators:− In order to increase or decrease the terminal voltage of a generator, A voltage regulator (a rheostat) or a variable resistance is used. In a shunt generator,
  • How To Work Voltage Regulation In Generators

It is connected in series with shunt field winding; and in a series generator, It is connected across the series field winding, As shown in figure 29.
Whats Is Voltage Regulation In Generators And Uses Of D.C. Generators

In the series generator, The voltage regulator is known as diverter also. It regulated (controls) the series field current and hence the terminal voltage. If the diverter has a low resistance, then its current will be more and the series field current will be low, Hence the terminal voltage will be low. Similarly, for high diverter resistance The terminal voltage in high.
  • What Is Uses Of D.C. Generators

Different types of generator are used for different purpose.

which are as follows:
⇒ Uses of series generator-
It is used for arc-welding, arc-lighting and as a booster in the electric distribution system.
⇒ Uses of shunt generator-
It gives a fairly constant voltage, therefore, it is used for lighting battery charging and power supply purposes. it has an advantage of a low voltage drop in its regulator.
⇒ Uses of compound generators-
It can maintain a constant terminal voltage over a wide range of load variations. Hence, it is used for traction loads (the load, whose value can be changed all of a sudden), e.g. cranes, trams, etc. It is used to reduce the voltage drop of a long feeder line.
