what will happen when reverse reactive power occurs in
alternators?
Answer Posted / ramji
When reverse reactive power occurs the outgoing current in
the particular alterntor will go high and it will trip on
overcurrent.Also this conditon occurs when excitation of
the subjected alterantor fails when it is connected
parallel with other alternator or grid.Also this condition
occurs when the rotating diode of alternator fails when
them machine is ruuning.If wrong pls correct me.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
hi every body i am master student in control engineering and my project is slip control in trains i assumed a Dc motore as traction motor but i don't have characteristics of this kind of motor that is used in train. i want from every body if he or she has the characteristics or information about Dc motor that is used in train give me those information or technical characteristics .
