How can field distortion be remedied? Last Answer : By using compensating winding which are embedded in the slots in the pole-shoe and are connected in series with the armature...
Should the brushes of a loaded generator be placed in the neutral plane? Last Answer : No, because the brushes must be advanced by a certain angle (called brush lead) beyond the neutral plane to prevent sparking...
What is the difference between an Insulator and a Dielectric? Last Answer : Dielectrics are used to store the electric charges, while insulators are used to block the flow of electric charges. All dielectrics are insulators (they don’t allow the flow of electric charges through them) but all insulators aren’t dielectric because they can’t store charges, unlike dielectrics....
State the difference between a four-point starter and three-point stater? Last Answer : The shunt association in four-point stater is provided unconnectedly from the line whereas in three-point stater it is associated with a bar which is the negative aspect in three-point stater....
What are the conditions to be fulfilled by for a dc shunt generator to build back emf? Last Answer : The generator should have residual flux, the field winding should be connected in such a manner that the flux setup by field in same direction as residual flux, the field resistance should be less than critical field resistance, load circuit resistance should be above critical resistance. ...
