What are the differences of Long shunt vs short shunt generator?

In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.


Magnetising characteristics of DC shunt generator?

the magnetizing curve is the relation b/w air gap flux and the field winding current armature EMF. the resulting curve is called magnetizing characteristics or open circuit characteristics. at any speed by recognizing that the induced emf is directly proportional to the speed


How will a shunt generator behave if the field resistance is greater than the critical resistance?

the shunt generator wont be started .hehe


What is the theory of conversion of AC to DC using 3-phase induction motor and DC shunt generator?

The theory of converting AC to DC using a 3-phase induction motor and a DC shunt generator involves utilizing the induction motor to mechanically drive the shunt generator. When the induction motor is powered by a three-phase AC supply, it operates and drives the rotor of the connected DC shunt generator. This generator then converts the mechanical energy into electrical energy, producing a DC output. The process allows for efficient conversion of AC to DC, leveraging the motor's mechanical properties and the generator's electrical characteristics.


What has to be interchange in order to reverse the direction of rotation of shunt generator?

the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover

What is excitation in generator and 2 methods each?

when the current is passing through the winding then it is called "Excitation". Types of excitation (1)seperately excited generator. (2)self excited generator. self generator is classified into 3 types. 1.shunt generator. 2.series generator. 3.compound generator. compoud generator is again classified into 2 types. 1.short shunt generator. 2.long shunt generator.


Why a dc shunt generator may fail to self excite?

If there is no residual magnetism in the field poles then there would be no flux too induce the initial voltage for self exitation


What is the difference between a seperately excited DC generator and DC shunt generator?

The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
