The open-circuit characheristics and the load characheristics
load test on dc shunt generator is a test to plot the internal and external characteristics of the 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.
in swin burn test we find out the copar loses & iron loses of the dc generator
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.

to find the relation between emf generated and Field current .....
It does have armature resistance.
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
A shunt generator is a type of DC generator that does not use a permanent magnet. Reducing the speed of the generator will reduce the output, but not the load the generator requires because the currents in the parallel branches are independent.
in swin burn test we find out the copar loses & iron loses of the dc generator
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance at a given speed it is the maximum field resistance with which the shunt generator excite.
By the operation supply 1.AC generator 2.DC generator In DC generator we are having the following types according to the construction 1.DC Series Generator 2.DC shunt Generator 3.DC Compound 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.
