MY homemade kilowatt hour meter table lamp. this is where i do all my testing
of bulbs and light fixtures, and i have a 120 Volt plug on the back of it
so i can plug in fixture for test. one revolution it put 1 2/3 watt-hour on the

Problem with power measurement on these home meters is their power range being too high for measuring a single lamp (mainly CFL and/or LED replacements), so the accuracy is not as good. What would help is the use of current measurement transformer to boost the current by e.g. factor of 5. Then the meter would work in way more accurate range (it will see the same factor of 5 higher power, so you would have to divide the "result" by that number), so the measurement would be back within the nominal 2% accuracy of these meters.

No more selfballasted c***

I use the meter for general idea what pulling watts and what not pulling it. but it been calibrated. i uesed this when i was in waco becase i have a roomate burns leave crap on and all of that stuff. so i built me this meter to take the balance. so he can pay the fare shere of the bill while. i am being energy conserver. ran a one watt led the wheel took 90 min to compleat it round. the meter really spins when i plug in a 1000 watt bulb. it rated for 15 amps

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

I did add a CT to a meter to multiply the current by 10, to get it into the lower loss part of its curve without having to change the current shunt. Old tape wound permalloy core with a single turn secondary and a 10 turn primary, connected to the current shunt. Currently tells me I have used 317.3 kWH in 18 months.

That meter is only for the computer, and includes the UPS charging current, the DSL router and the powered speakers I built. Also includes the socket outlets for the work area I have in my bedroom, including a set of 50VA isolated outlets for safety purposes. Works out to around $50 in power.

By the way these electromechanical meters tend to be quite power hungry devices - ~5W (I mean 5W, not VA) for the voltage coil is quite an average consumption without any load.

yea it does tend to be a bit a powerhog it put 5 bucks on the utilty bill at home using it 24/7 with no load.
I like the CT idea to make it turn a bit faster. but i never hook one up for a meter. any way it good enough
for my application wanted to keep it simple. not my everyday lamp.
