Factors involved in the voltage build up of shunt generator, Electrical Engineering

Assignment Help:

Q. List and explain the factors involved in the voltage build up of shunt generator.

Ans.

following factors are involved in voltage build up of shunt generation

 

(1) There must be same residual magnetism in poles.

 

(2) For the given direction of rotation the shunt field coils should be correctly connected to the armature i.e. they should be so connected that the induced current reinforce the emf produced initially due to resident magnetism.

 

(3) If excited on open circuit its shunt field resistance should be less than the critical resistance.

 

(4) If excited on load, then its shunt field resistance should be more than certain minimum value of resistance which is given by internal character.
