Electrical Engineering : Dc Generators QUESTIONS AND ANSWERS :: part5 : 6 to 10
Following Electrical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :
6.When two D.C. generators are running in parallel an equilizer bar is used |
| to increase the series flux |
| to increase the generated e.m.f. |
| to reduce the combined effect of ar-mature reaction of both the machines |
| so that the two identical machines will pass approximately equal currents to the load |
7.The essential condition for parallel operation of two D.C. generators is that they have ' |
| same kW rating |
| the same operation r.p.m. |
| the same drooping voltage charac-teristics |
| same percentage regulation |
8.Shunt generators are most suited for stable parallel operation because of their |
| rising voltage characteristics |
| identical voltage characteristics |
| drooping voltage characteristics |
| linear voltage characteristics |
9.A shunt generator can self-excite |
| only if the resistance of the field circuit is less than critical value |
| only if the resistance of the field circuit is greater than critical value |
| irrespective of the value of the resis-tance in the field circuit |
| only if the resistance of the field circuit is less than critical value |
10.A series generator can self-excite |
| only if the load current is zero |
| only if the load current is not zero |
| irrespective of the value of load current |
| none of the above |
