Power factor improvement aims at optimal utilization of electrical power, reduction of electricity bills, and reduction of power loss. Power transformers are independent of P.F. If the power factor is close to unity, for the same KVA rating of the transformer more load can be connected. (Better the power factor lesser will be the current flow).

$begingroup$ @PlasmaHH I imagine taking a DC power source and charging a large electrolytic capacitor. Then switch the polarity on the capacitor and marvel at the giant spark, then do that again, and again, 120 times per second. That was what I imagined happening when AC is applied to a capacitor.

Since capacitors have a leading power factor, and reactive power is not a constant power, designing a capacitor bank must consider different reactive power needs. For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR. ...

Power Factor Correction by Capacitor Banks. In a three-phase system, the power factor is improved by connecting capacitors in star or delta.
Power Factor Values. For the purely resistive circuit, the power factor is 1 (perfect), because the reactive power equals zero. Here, the power triangle would look like a horizontal line, because the opposite (reactive power) side would have zero length. For the purely inductive circuit, the power factor is zero, because true power equals zero.
