A utility reports a transmission and distribution loss of 22 per cent and an aggregate technical and commercial loss of 18 per cent. The figures are

  • A.consistent, the two measuring different things
  • B.consistent if the collection efficiency exceeds one hundred per cent
  • C.consistent only for a utility with no industrial consumers
  • D.inconsistent, the aggregate measure cannot be the smaller

Answer: D

The aggregate measure includes the transmission and distribution loss and adds the failure to collect, so it can never be smaller. A reported figure of that shape indicates an error in the computation or in the definitions used.
