Dave,

I have used a PZ4000 Power Analyzer to do some measurements on my DRSSTC
systems, however, it was quite susceptible to radiated noise from the DRSSTC
and frequently locked up and rebooted at times.  Not sure how other units
would react under similar circumstances . . .

Folks

I got this excellent power measurement primer from Yokogawa Electric
(Yokogawa Corporation of America [YCA] for us in the 'States).

http://www.yokogawa.com/tm/tr/tm-tr0605_06.htm

I use Yokogawa WT20xx, PZ4000, and WT3000 powermeters/analyzers
at work and they are the "top of the metrology pyramid" for AC power
measurement capability.   They are used pretty exclusively by power
utilities for substation/feeder loading surveys, large load power
monitoring, motor / transformer efficiency measurement, etc.

I have been to their SOTA Tier 2 Calibration facility
in GA (Atlanta Region).  Their equipment is pricey (WT2010 single phase
wattmeter is 10k, 2030 or 3000 is 20k + options), but excellent deals can
occasionally be had on surplus market.  Alex Tajnsek picked up a
serviceable "second generation" WT2533 (predecessor to WT20xx series)
DSP wattmeter for $20 US (no joke) at the Richmond salvage yard in
a box buried under some tech manuals and miscellaneous parts.

Yep, fully functional, and even had a still valid cal sticker on it...
:^D

So guess what we are going to use to measure power on his TC's???
