Objective: To obtain external characteristics of a dc shunt generator
Preview:
The self excited DC shunt Generator is coupled to a DC motor, which acts as prime mover. Two characteristics are more important. The internal or total characteristic that gives the relation between the emf actually induced in the armature and the armature current. This is of interest mainly to the designer. The external characteristics called performance characteristics (also voltage regulating curve) which give the relation between the terminal voltage and load current. This curve lies below the internal characteristics due to armature drop. This is important in judging the suitability of a generator for a particular purpose. These characteristics can be obtained by a load test with total field resistance remaining fixed as the speed is to be kept constant.
