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?

    Hi, thanks for the replies.


    This is for a lab system.  Mostly rack equipment, control cabinet with switched-mode PSUs and electronics.


    I'm assuming equipment rating plates usually display peak RMS power?  The nominal operating voltage (230V AC) and frequency (50Hz) of the supply at the installation location have been provided so I presume no need to test at the lower limits of the switched-mode PSUs?


    Parts of the system fall under the Machinery Directive.
