An induction generator connected to a network draws from it

  • A.a direct current for its rotor excitation
  • B.its magnetising reactive power
  • C.the whole of its real power output as well
  • D.nothing at all

Answer: B

Having no field of its own, it needs the network to supply the reactive current that establishes the flux. Standing alone it requires capacitors, and controlling the voltage and frequency of such an arrangement is awkward.
