Give the effective self-exciting capacitance at 1900 rpm and 60 Hz of an induction generator having a rated self-exciting capacitance of 180 μF and a load connected across its terminals of RL = 50 Ω and L = 0.05 H.
What would the effective capacitance be if the frequency went up to 65 Hz?
What would the new value of the real capacitance be to keep the self-exciting point at its original value?
