HI All,
For plug in watts/PF meters is there a better or more accurate one
that anyone recommends?
I've tried the Kill-a-watt and seems to work and be pretty accurate,
but haven't compared it to many others.
I've been testing some CFLS vs LED and the PF is way better on the LED.
For us of
wrenches,
i have a question about my home's system. i was one of the first net metered
systems in our area, so the utility company installed a fancy dual register
meter which also displays kvar/power factor.
when selling 1 kW today the power factor was .40 and the kvar was 2.37.
this sounds ho
Hi All,
I'm looking to upgrade my meter selection.
I'm looking for a powerfactor meter and oscilloscope to better help
in diagnostics of inverter/generator issues.
I've seen a pretty inexpensive hand held oscilloscope from Velleman #
HPS10 for $135, but its not a power factor rated.

Power factor on DC? As far as I know, power factor / vars is an AC phenomena
where current and voltage are out of phase.

Might that have changed?

I'd suggest a differential voltage probe and a current probe with a two
channel scope. Observe both waveforms simultaneously. Phase shift
(PF), amplitude, waveshape, harmonics, etc all at one time. Most
digital scopes you can store the waveforms, download them to your
computer, or just take
Hi Jay,
Take a look at the Fluke 125 Power Scope. It's about $1500. It looks like a
pretty sweet meter. I think it will do what you're looking for.
Multi-channel DVOM + AC Power + Power Factor + More. The clamp doesn't do DC
amps, so that's a bummer.

I recently spoke with an inverter manufacture and I left with the following
opinion. Normally the inverter takes the unity power factor load and leaves

Darryl,
The inverter is reducing the real power used by the customer but not
the reactive power. So it does make the power factor worse when you
are looking at from the utility meter. Since most customers don't pay
for reactive power it doesn't matter to them. But some customers do
