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.
The temperature dependence of resistance is also quantified by the relation R2=R1[ 1+(T2T1) ] where R1 and R2 are the resistances at temperatures T1 and T2, respectively, and is known as the temperature coefficient of resistance. If a copper wire has a resistance of 55 at 20C, find the maximum permissible operating temperature of the wire if its resistance is to increase by at most 20. Take the temperature coefficient at 20C to be =0.00382.
