The generator is connected to two electrodes are placed in the ground 1000m from each other. The AC current flowing through the ground between the electrodes has a peak value of 250 mA . (a) Calculate the resistance of the ground. (b) Write the expression for the current as a function of time. (c) Calculate the instantaneous current at a time of 0.040 s.
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
