Webb7 aug. 2014 · Advantages and Disadvantages The separately excited dc generators have a decided advantage over the self-excited generators – it operates in a stable condition with any field excitation. Thus a wide range of output voltage may be obtained. WebbThe excitation current of a DC shunt generator is determined by the output voltage and the field resistance of the generator. In most DC shunt generators the excitation is kept at about 0.5 percent to 5 percent of the generator's overall electrical output. In this type of generator, the voltage output is very steady as long as the generator works within its … Webb1. It runs at a constant speed (synchronous speed). The only way to change its speed is to vary the supply frequency. 2. It is not inherently self-starting. 3.

Webb24 feb. 2012 · These type of DC generators generally give constant terminal voltage for small distance operation with the help of field regulators from no load to full load. They are used for general lighting. They are used to charge battery because they can be made to give constant output voltage. They are used for giving the excitation to the alternators. WebbFor dc power generation, the separately excited generator has acceptable voltage regulation, but has the disadvantage of requiring a separate source. The self - excited shunt generator does not require a separate source, but has poor regulation. The cumulative compound generator overcomes this problem; it can be designed to have
