What is meant by compound generator?
[′käm‚pau̇nd ′jen·ə′rād·ər] (electricity) A direct-current generator which has both a series field winding and a shunt field winding, both on the main poles with the shunt field winding on the outside.
What is the voltage regulation of a DC compound generator?
Ideally DC generators should have zero voltage regulation.
Any increase in load current causes an increase in the field and hence the terminal voltage rises. Hence it has negative voltage regulation and it has the poorest voltage regulation.
What causes a generator to become over compounded?
As the load current increases, the current through the series field winding increases, increasing the overall magnetic field strength and causing an increase in the output voltage of the generator. … This type of generator is called an over-compounded generator.
What are the type of compound generator?
There are two types of compound wound generators, the series field winding and the shunt field winding. There are two windings, one in series with the armature and the other in parallel with it. There are two types of DC generators- short and long compound-wound.
Which generator best voltage regulation?
In such a generator, the induced voltage on no-load would be the same as for the shunt generator because series field does not create any flux. So it behaves like DC shunt generator, which has a very good regulation.
What is generator regulation?
Large AC generators commonly use a combination Exciter-Voltage Regulation system to maintain generator field current under varying electrical loads. The basic voltage regulation system is designed to automatically regulate generator output terminal voltage within close tolerances of a specified value.
What is voltage regulation in DC motor?
Definition: The speed regulation of a DC Motor is defined as the change in speed from no load to full load. It is expressed as a fraction or a percentage of the full load speed.
Why do we calculate voltage regulation?
Voltage regulation is the measure of how well a power transformer can maintain constant secondary voltage given a constant primary voltage and wide variance in load current. The lower the percentage (closer to zero), the more stable the secondary voltage and the better the regulation it will provide.
What is the meaning of voltage regulation?
In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line.
