What is the probable cause for no voltage generated in a DC compound generator?

In any DC generator the causes to fail to produce voltage is loss of residual flux in the field or fields , poor brush contact in the commutator(clean the brushes and commutator) , check all the terminals of the generator and voltmeter may not be functioningand lastly check the coupling and the prime mover is rotating.

What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
What is demagnetising effect of DC generator?
demagnetising effect of dc generator is to reduce main field flux there by reduction in generated voltage.
What is generated voltage?
I guess it depends on the design of the generator. In the plants I know in th UK it is usually 11 KV
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
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.
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
How do electrical energy generated?
It is usually generated in a generator; read the Wikipedia article on "Generator" for more details. Briefly, this uses the physical principle that if a material is moved through a magnetic field, a voltage is generated. If such a material is a conductor, and appropriately connected, this voltage will cause an electrical current to flow.
What is demagnetising effect of DC generator?
demagnetising effect of dc generator is to reduce main field flux there by reduction in generated voltage.
What is Tacho generator?
Taco generator is the one which is attached to the shaft of big rotating machine to find out its speed. It converts the the rpm in to voltage i.e. the voltage generated in the small generator is directly proportional to the speed of the shaft to which it is attached meter attached to this generator is graduated in rpm instead of volts .
When a generator is running and if no electrical load is attached to it where do the electrical energy generated go to?
hi, when generator is running on no load,it is having its own load because of it produce some voltage drop,result electric energy is generated.
What is generated voltage?
I guess it depends on the design of the generator. In the plants I know in th UK it is usually 11 KV
Is it true or false that a tacho-generator generates an ac voltage?
True! Depending on the designed specifications of the tacho, the voltage generated is usually in the range of around 0 to 36 volts.
How you get electricity?
Electricity is a concept and exists everywhere, even in vacuum. Hence you can not "get" electricity. An electrical current can be generated by connecting two voltage sources of different potential with a conductor. A voltage can be generated with an electromagnetic generator. An electromagnetic generator generates voltages by moving electrons in a conductor through a magnetic field, causing a force upon the electrons.
What are the differences between the parts of a generator and the parts of a motor?
In principle a generator is the same as a motor. In a dc motor the voltage generated by the rotating armature is slightly less than the supply voltage which causes power to flow in from the supply. If an engine is then coupled to the shaft causing it to rotate faster, then it generates more voltage and power flows back into the supply. That is how a motor becomes a generator.
What happens to the generated voltage of a self excited generator if shunt field resistance is greater than the critical resistance?
it doesn't develop emf ..........
What is commutation in DC machines?
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
What is the off load voltage of the generator?
Terminal voltage is the voltage between the output terminals of a generator.
