This is an industrial meter, measuring demand (KVA) and KWH. Medium
sized industrial plant.

If the meter claims to read kWh, then you can take it to the bank that
it does in fact read kWh. Most revenue meters are able to measure the
real power being used directly without external pf correction.
=A0=A0=A0=A0The meters do not get corrected, idiot. The LOADS do!
=A0=A0=A0=A0Tariffs for
industry often require additional metering if there is unusual load
connected.
=A0=A0=A0=A0No ****, dumb****. That is what I said.
=A0=A0=A0=A0Very low pf can be an issue because of the impact on system
voltage. The possibility of high, short-term demand often incurs an
additional tariff where you have to pay based on the highest 'peak'
during a
billing cycle. It sounds like this is what you have.
=A0=A0=A0=A0Why don't you just make **** up as you go, DaeTurd?
-----------------------
Industrial demand metering measures peak KVA demand -not power factor.
Energy metering inherently measure the kWh used without the need for a
power factor "correction".
This is no different now, except for the metering equipment, than it was
70 years ago.
Customer loads do not "have" to be pf corrected. If low power factor at
the loads add to the peak demand KVA (and this may not be the case) then
it would be economic for the customer to add some correction such as
capacitors or even synchronous motors. If the low pf is at a light load
time, it may not be worth the effort. It is not a great task to decide
what is the optimal correction (which will not be to unity pf) for a
given situation.
Please,
when you have the knowledge that Daestrom has, then you can make
sensible comments without the childish invective. Otherwise go and play
with Roy.
By the way, top posting is far less offensive than your abusive
approach.

Nice save Don, but I don't play with trolls., I just throw rocks at them
& watch them run away - actually I think we've (I've) addressed him more
than enough.
