Scott Little posted this at vortex, it is a most interesting comparison
of how you can use one of those house utility meters to measure power
used in a load. I've always wondered about their accuracy and Scott now
has provided an excellent insight into their use. The email follows;
-----------------------
My Westinghouse watthour meter (Kh=1) stacks up against our Clarke-Hess
2330 on a resistive load as follows:
2330 Westinghouse W/3220 ratio
71.1 68.2 .959
129 127 .984
201.5 200.5 .995
315 317.2 1.007
425 424 .998
660 657 .995
660 657 .995 (repeat)
805 803 .998
972 971 .999
At the lowest power level, 71 watts, the wheel took 52.77 seconds to
revolve...i.e. really slow. Perhaps the apparent fall-off in the
watthour meter's response at low power levels is the result of friction
in the wheel's support bearing.
Anyway, above 200 watts, the watthour meter is just great...on a
resistive load.
-----------------------
So, a redneck power measuring system would use two of these watthour
meters...one on the input side of your free energy device so you could
see how much real power your circuit was USING.
Then one on the output side from the circuit to the load to determine
how much power your LOAD was actually using.
Clean, simple, CHEAP....and from Scott's info, I'd say a very good
measure of the actual IN to OUT power....
