Question
A 411-V long shunt flat-compound generator delivers 28 KW to a load.
The armature resistance is 0.477 ohms, the shunt field resistance is 76
ohms, the commutating field winding resistance is 0.35 ohms, series field
resistance is 0.338 ohms, and diverter resistance of 0.498 ohms. If the iron
and friction losses are 601 watts, determine the commercial efficiency of
the generator. Draw the equivalent circuit of the generator and the
corresponding values of the components.
Determine the following: a) eletrical b) mechanical and c) commercial
efficiency
Note:
Write the equivalent numerical value of the commercial efficiency
(percentage) of the generator in the given space below.
The other required values will be verified in your submitted solution.
