WebA shunt generator is to be converted into a level compounded generator by the addition of a series field winding. From a test on the machine with shunt excitation only, it is found that the shunt current is 3.1 A to give 400 V on no load and 4.8 A to give the same voltage when the machine is supplying its full load of 200 A. WebA dc shunt generator, when driven without any excitation, showed an open circuit voltage of 12 V. When the field winding was excited, the voltage dropped to zero. It happened because field resistance was higher than critical resistance there was no residual magnetism in the field circuit field winding was wrongly connected
WebNov 18, 2015 · The shunt field current is given as: Terminal voltage is given as: If the brush contact drop is included, the terminal voltage equation is written as: In this type of DC generator, the field is produced by the shunt as well as series winding. The shunt field is stronger than the series field.
A shunt generator is a type of electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current for the excitation (generator is therefore self excited). See more A shunt field (and any series resistor used for adjustment) may be directly connected across the armature terminals in parallel with the load. Where the machine has a series compounding winding, the field may be connected at the … See more Current in the field windings of a shunt-wound generator is (approximately) independent of the load current, because currents in parallel … See more In a shunt-wound generator, output voltage varies inversely with load current. In a series-wound generator, output voltage varies directly with load current. A combination of the two types can overcome the disadvantages of both.
