Characteristics of DC Generators - Shunt, Series & Compound

WebIn this case, the generator is classed as separately excited. Alternatively, it may be noted that the output of the DC generator is unidirectional and therefore may be used as a source to supply its own field current, as shown in Figure 7B. In this case, the generator is referred to as shunt-excited. WebExternal Characteristic. The external characteristic of a shunt generator can be obtained by conducting a load test on it in a manner similar to that described for a separately excited generator. The connections are made as shown in Fig. 1 (a). The machine is driven at a normal speed and field current is adjusted to obtain rated no-load voltage.
