From my days studying electronics (or as I recall), PFC was basically
implemented to correct usages in current for the meter man.
How true is that? Is there any performance to be gained with the device
after correction?
This advice from Energy Australia:
===================================================================
Most residential classification customers are metered by a spinning
disc meter, or a basic electronic meter which does not have enough
"smarts" in the meter device to enable billing to be carried out at a
KVA pricing.
Currently small customers are billed on KWh pricing, and KVA Demand
pricing usually relates to large commercial and industrial
installations where poor power factor may impact upon the EA network,
and there may be an economic billing benefit in the customer pricing
to ensure that Power factor is closer to Unity.
