roblem 2 The following two three-phase loads are connected to a three-phase system of 311.13 cos (377 t) V line: 1) Three-phase induction motor of 10000 VA in Y with a power factor of 0.6 2) Three-phase load balanced in Δ with Zf = 20 ∠ 323.13 ° Ω. Please find a) total current in each line, b) the apparent and reactive power and c) the copper losses that occur.
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.
