26 Asiacell 2 9:Y0 O1%V 36 lor B/s Asiacell 2nd exp..p... > E. Report : - - For all graphs, origin should be ( 0 ) volt and CO) amp. 1- Plot all the 4 external characteristics, i.e. for A ) separate excitation, (B ) self excited shunt, (C) compound excitation cumulative and differential in the same graph sheet. V. in y - axis and IT, in x - axis. 2- Experiment A : Calculate the internal characteristic which is the plot of the induced emf against the load current. Assume the armature reaction to be negligible. Plot the internal characteristic and the external characteristic in the same graph sheet. 3- Experiment B : Determine the internal characteristic and plot external and internal characteristics in the same graph sheet. 4- Experiment C : Determine the internal characteristic and plot them along with the external characteristic in the same sheet. 5- Why should the terminal voltage drop more in the case of shunt generator than in the case of separately excited generator as the load current is increased ? 6- Why it is possible to short circuit the differential compound generator and not the cumulative compound generator ? 2 - 5 Il> 220 v i D.C.
