RE: DATACENTER: inductive power measurement
I don't think you can pick that info off a normal power cord because both
leads are in the same cable and cancel each other out...I don't know much
about electricity though.....I had my electrician measure the draw of one of
the data closets by removing the bezel from the distribution (breaker) panel
and clamping over the stuff in there...there was no interruption in
power...your electrician should be able to do the same.....
Just for your info...generally a piece of equipment in the room that was
rated for say 5A was only drawing .5 or .3 fully loaded (these were Compaq
proliant 3000s and 1600s). I didn't check how much they draw on boot.
Cisco 7500 was drawing about 2A and was almost fully loaded (2A on each
power supply)

Subject: DATACENTER: inductive power measurement
We have seen a significant discrepancy between the actual and
computed power consumption in a rack (using the the manufacturer's
average consumption rating for the computation). Therefore, in
our power analysis, we would like to measure the actual power load
in addition to computing the theoretical peak and average rates.
Is there a inductive device that allows the power or current draw
to be non-intrusively measured (i.e. does not require the equipment
to be powered down or the breaker to be physically dismantled).
The 'Fluke Model 33' was recommended to me; however, I'm not sure
whether that is (or any device) has an inductive pickup that can
be used for non-intrusive power measurement.
Thanks in advance,
