1.4 A single-phase 480020° V bus is connected to a single-phase 100KW motor operating at a lagging power factor of 0.8, a lighting load of 200KW operating at a unity power factor, and static capacitors of 150kvar. Determine the following: (a) The total complex power supplied by the bus to the loads (b) The total current supplied to the bus (c) The power factor of the total load connected to the bus Consider Problem 1.4 and use the bus voltage of 480020° V as the reference phasor. Determine the following: (a) The phasor current of the lighting load. (b) The phasor current of the motor. (c) The phasor current of the capacitor. (d) The total phasor load current. (e) Draw the phasor diagram of the voltage, all three load currents, and show how the three 1.6 load currents combine to become the total load current in terms of phasor addition

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.
