In a round about way the harmonic requirement does serve the consumer. It all
boils down to having an efficient power distribution system. With so many
non-linear loads the power companies efficiency drops significantly, therefore
to maintain service to all our households (to watch the superbowl, blast our
stereos, surf the net, cook on your electric stove, have your kids turning on
every light in the house) they need to build more power plants (or nukes) and
they then pass that cost directly to you and me.
I think the issue may have been the power industry was extremely well
represented, its the ITE industry that wasn't.
Maybe PFC isn't such a bad idea.

Hi Rich.
You dropped a p.s. which caught my cynical eye...

My understanding is that the Committee (s) which grew IEC1000.3.2 and
3.3. were comprised of, in the majority, representatives from the
Power Generating Industry, and the poor old consumer didn't get a
look in. Subsequently, the principle was set that any problems with
the mains supply is the users, not the makers.
Perhaps that is a gross over simplification, but that's how it seems to me.
They never had these problems with steam, or coal, or water mills, or
windmills..... maybe we should go back.
