When a difference of potential is applied to a pair of electrodes immersed in an insulating liquid, a small conduction…

Power systems equipment must withstand not only the rated voltage (Vm), which corresponds to the highest voltage of a particular…

• The slow speed salient pole alternators are ventilated by the fan action of the salient poles which provide circulating…

Synchronous machines are principally used as alternating current (AC) generators. They supply the electric power used by all sectors of…

Fig. (3.6) shows the voltage build up in a series generator. Here R1, R2 etc. represent the total circuit resistance…

Voltage build up in a shunt generator depends upon field circuit resistance. If the field circuit resistance is R1 (line…

The following are the three most important characteristics of a dc generator: 1. Open Circuit Characteristic (O.C.C.) This curve shows…
