What is difference between series and shunt generator?

What is difference between series and shunt generator?

shunt field are parallel and hence have low current. Therefore it have more number of turns and core gets saturated due to which flux will be constant. Series generator have series winding and thus a high armature current is same as field current. Due to which resistance of field winding is low.

What is the downside to series generators?

The main disadvantage of series generators, Output voltage varies as the load varies The e. mf induced in the armature winding is constant with . time Inter pole winding is connected in series with main poles of d.c machine Series motor maintains a more constant speed under varying load.

What is a shunt type generator?

A shunt generator is a type of direct current electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current.

What are series-wound generators used for?

The series-wound generator is used principally to supply a constant current at variable voltage. If a motor or generator is series-wound, it has the field and armature circuits connected in series.

What are the general characteristics of shunt generator?

The general characteristic is shown in Figure 2.30. When connected to an external load the shunt-wound generator exhibits a drop in terminal voltage as the armature current is increased (see Figure 2.29). The drop in voltage in the shunt-wound generator is much greater than that in the separately excited generator.

What are the three types of self-excited DC generator?

The three types of self-excited DC generators are:

  • Series Wound Generators.
  • Shunt Wound Generators.
  • Compound Wound Generators.

What are disadvantages of a commutator?

The disadvantages of commutators are high consumption of electrical-grade copper, sparking, and wear caused by brush friction.

Where are shunt generators used?

Applications of Shunt Wound DC Generators

  • They are used for general lighting.
  • They are used to charge battery because they can be made to give constant output voltage.
  • They are used for giving the excitation to the alternators.
  • They are also used for small power supply (such as a portable generator).

What is the principle of shunt?

A shunt motor (known as a shunt wound DC motor) is a type of DC motor which is self-excited and has the field windings that are connected in parallel to the armature winding of the motor. As these two parts are connected in parallel, the armature and field windings are exposed to the same supply voltage.

Where is a DC generator used?

Applications of DC Generators These generators are used to charge batteries, provide lighting and provide excitation to alternators. They are used to provide field excitation current for regenerative braking in DC locomotives. They are used in DC motors where speed control is necessary.

How does a series-wound DC generator work?

A series-wound generator uses very low resistance field coils, which consist of a few turns of large diameter wire. The voltage output increases as the load circuit start drawing more current. Under low-load current conditions, the current that flows in the load and through the generator is small.

What’s the difference between shunt and compound wound DC generators?

In a series-wound generator, the output voltage varies directly with load current. In the shunt-wound generator, the output voltage varies inversely with load current. A combination of the two types can overcome the disadvantages of both. This combination of windings is called the compound wound DC generator.

What are the characteristics of a series wound DC generator?

A series-wound DC generator characteristic shows that the output voltage varies with load current. This is undesirable in most applications. For this reason, this type of generator is rarely used in everyday practice. 2. DC Shunt Generator

Can a series wound generator be used as a booster?

Series generators are rarely used except for special purposes e.g., as boosters. A series-wound generator uses very low resistance field coils, which consist of a few turns of large diameter wire. The voltage output increases as the load circuit start drawing more current.

How is the Shunt winding connected to the generator?

In a shunt generator, the field winding is connected in parallel with the armature winding so that the terminal voltage of the generator is applied across it. The shunt field winding has many turns of fine wire having high resistance. Therefore, only a part of armature current flows through shunt field winding and the rest flows through the load.

Therefore it have more number of turns and core gets saturated due to which flux will be constant. Series generator have series winding and thus a high armature current is same as field current.
