Concept:
The current is given as for star connected motor,
Calculation:
Given that,
R1 = 0.3 Ω, R2 = 0.3 Ω, X1 = 0.41 Ω, X2 = 0.41 Ω
Frequency (f) = 60 Hz
For star connected induction motor,
When supply is charged to 80 V (line), 20 Hz, reactance offered by stator & rotor will be changed because of change in frequency {∴ x ∝ f}
At 20 Hz, equivalent circuit can be drawn as,
Ist = 70.05 A
