Assertion: a fixed capacitor bank sized for full load is satisfactory at all loads. Reason: the reactive requirement of a plant is constant.

  • A.the assertion is true but the reason given for it is false
  • B.the assertion is false although the reason offered is a true statement in itself
  • C.both the assertion and the reason are true and the reason explains the assertion
  • D.both the assertion and the reason are true but the reason does not explain the assertion

Answer: B

The magnetising component of an induction motor is indeed nearly constant, which is what the reason states, but the total reactive demand still falls with load, and a bank sized for the peak over-corrects at night. An automatic stepped bank is what tracks it.
