Please solve this problem step by step and illustrate your answer properly. Write your answer in a piece of paper please. Box the final answer.
In a certain sub-station, there are 5 d.c. shunt generators in parallel, ench having an armature resistance of 0.1 0, running at the same speed and excited to give equal inducnd emfs Each generator supplies an equal share of a total load of 250 kW at a terminal voltage of 500 V into a load of fixed resistance. If the field current of one generator is raised by 4%, the others remaining unchanged, calculate the power output of each machine and their terminal voltages under these conditions Assume that the speeds remain constant and flux is proportional to field current
A 10-kw 250-volt compound (long-shunt) generator has a no-load voltage of 230. The shunt field has 800 turns per pole and the seriesfield 8.5 turns per pole. The shunt- and series-field resistances are 80 ohms and 0.07 ohm, respectively. To make the generator flat-compound, it will have a noload voltage of 230 and a full-load voltage of 230; the series field must produce 225 amp-turns. Calculate the total number of ampere-turns provided by each pole at no load and full load.
A short shunt compound generator delivers 150A at a terminal voltage is 230V. The shunt field current is 2.5A. The resistances of the armature, series field and diverter are 0.032-ohm, 0.015 ohm and 0.03 ohm, respectively. Calculate the electrical efficiency of the generator at this load.
