Measuring peak power for rating plate

M. Joshi
I would like to measure the peak power drawn by various pieces of equipment individually so that the figure can be shown on each equipment's rating plate.


I'm considering using the peak demand function on a MID power meter but, using 0.5s/0.2s CTs instead for better accuracy.  Is this approach acceptable?

    I can't help wondering if the term "peak power" is well enough defined to put on a rating plate.

    I once researched why a particular piece of aircraft equipment occasionally blew its fuse when in an aircraft but never in the lab and discovered that, depending on just when in the cycle it was turned on, it could draw anywhere from 1 to 100 times its steady state current at switch on.

    I would not know what value to use for its peak power.
