A self-excited generator has better regulation because it utilizes its own generated voltage to maintain the excitation of the field winding, allowing it to adjust automatically to changes in load. This inherent feedback mechanism helps stabilize the output voltage under varying conditions. Additionally, the generator can respond quickly to fluctuations, ensuring consistent performance and reducing voltage drops. Overall, this self-regulating capability enhances efficiency and reliability in power delivery.
What else can I help you with?
What are the causes of failure of self excited generator?
there is problem in AVR and magnetic strength.
Can you use the separately excited shunt generator machine as self excited generator?
You have a seperately excited generator and then you have a shunt generator which has the field winding in parallel with the armature terminals. In DC machines a separately excited generator could be run as a shunt generator provided the field winding is designed to work on the generated voltage. A separately excited alternator needs a DC supply for the field winding. In car alternators that is taken from the main winding via a rectifier and a voltage regulator.
Generator how it excite its self?
A generator excites it self due to a high power thyristors feeding to a rotor through slip rings. Once excited it lessons maintenance and operational requirements.
How the doubly fed induction generator build up voltage?
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
How residual magnetism present inside the self excited generator?
Residual magnetism in a self-excited generator refers to the small amount of magnetism that remains in the magnetic core after the generator has been de-energized. This residual magnetism is crucial for the initial excitation of the generator because it provides the necessary magnetic field to induce voltage when the generator is started. As the rotor turns, the residual magnetism induces a small voltage in the stator windings, which, when connected to the field windings, enhances the magnetic field and leads to self-excitation, allowing the generator to generate power. Without sufficient residual magnetism, the generator may fail to start or produce voltage.
Different types of DC generator?
There are two types me dc generator 1 separately excited dc generator 2 self excited dc generator
What is a brush less generator?
It is self excited generator, no external excitation circuit.
What is separately-excited generator?
in a separately excited generator the field coils are excited from a separate source like a dc battery may be or any other small generator. They are self starting generators.
Answering Which one is a separately excited generator - ac generator or dc generator?
Excitation is the phenomenon by which you control the excitation of field winding of a generator. In DC generator field winding is placed on stator and this field winding can be self excited or seperately excited depending upon the type on generator used. AC generators can also be self excited or seperately excited type but field winding is placed on rotor nad armature winding on stator.
What are the causes of failure of self excited generator?
there is problem in AVR and magnetic strength.
How you control the speed of self excited dc generator?
Easy. By controlling the speed of the motor or whatever is turning the generator's shaft.
What is excitation in generator and 2 methods each?
when the current is passing through the winding then it is called "Excitation". Types of excitation (1)seperately excited generator. (2)self excited generator. self generator is classified into 3 types. 1.shunt generator. 2.series generator. 3.compound generator. compoud generator is again classified into 2 types. 1.short shunt generator. 2.long shunt generator.

Why terminal voltage of a self excited shunt generator decreases with an increase of load?
The terminal voltage of a self-excited shunt generator decreases with an increase in load due to an increase in voltage drop across the internal resistance of the generator. As the load current increases, the drop across the internal resistance also increases, reducing the output voltage available at the terminals. This effect is known as voltage regulation and is a common characteristic of self-excited shunt generators.
How the doubly fed induction generator build up voltage?
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
