I would really appreciate help in answering any of these questions. I am new to learning about generators, however, I must be able to answer these questions. Please help if in any way possible. Thanks!



1) What type of insulation material is used for generator stator windings?

2) What is the stator and rotor core construction?

3) What is an el CID tests?

4) Where are RTDs usually located inside generators?

5) What type of systems are used to regulate generator gas temperatures?

6) What is the generator capability curve and how does it work?

7) How does the DC power from the exciter get to the rotor windings?

8) What are retaining rings used for and what are they usually made of?

9) How do we calculate the amperage in that a generator produces knowing the design voltage and design KVA of the generator?

10) What is MLE and OXL?

11) How is lagging and leading vars regulated on generators?

12) How long can generators motor? What can occur if they motor too long? Should there be trips associated with motoring?

13) Why is hydrogen used to cool the generator?

14) Why is it necessary to purge the system from air to CO2 to hydrogen?

15) What system is used to measure hydrogen purity?

16) What is the core monitoring system?

17) What prevents a generator from exceeding its rated voltage?
