A single phase 10 kVA, 50 Hz transformer with 1 kV primary winding draws 0.5 A and 55 W, at rated voltage and frequency, on no load. A second transformer has a core with all its linear dimensions 2 times the corresponding dimensions of the first transformer.The core material and lamination thickness are the same in both transformers. The primary windings of both the transformers have the same number of turns. If a rated voltage of 2 kV at 50 Hz is applied to the primary of the second transformer, then the no load current and power, respectively, are
A synchronous motor is running from an infinite bus of voltage V1 in steady-state, at about 50% of its rated load with a power-angle 1 between Vt and Ef (induced voltage). The load is suddenly decreased to 25%. Ef attains its new steady-state power angle 2 with Vt by initially
