Power Factor


Lehman Engineering Power Quiz
"Power Factor"

Consider the three phase distribution system and the linear load as shown:


The linear load is operating at a Power Factor of 0.7 lagging. It is desired to bring the Power Factor of the system up to unity (i.e. 1.0). A capacitor bank has been sized and designed to provide the necessary KVAR.

Question #1:
Where would you place the Power Factor correction capacitor bank?

  • Point A - (at the service entrance) or at
  • Point B - (halfway between the service entrance and the load) or at
  • Point C - (at the load)?
