You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
A load can be considered to be capacitive, resistive or inductive in nature.a) Discuss the differences between these types of loads. Your discussion should include the following: A description of the type of the load and why it is considered to be capacitive, resistive or inductive. How/whether energy is stored. An example where possible, and a comment on how common that type of load is. How the load will respond to a sudden removal of the driving voltage.
