Mains power analysis

Post by scoop » Fri Oct 25, 2019 1:25 pm

Hi,

I do have an older Picoscope 2205, that I would like to use to measure power and power factor of various AC/DC applications.

There is a very good tutorial here
https://www.picotech.com/library/application-note/analysing-mains-power-with-picoscope

Other companies state that they need to calibrate the current probes with the oscilloscope, but this does not seem to be the case here? Would I be able to measure AC power by buying a
- High voltage probes (https://www.picotech.com/accessories/high-voltage-active-differential-probes/25-mhz-700-v-differential-probe)
- Current measurement (https://www.picotech.com/accessories/bnc-current-probes/60-a-current-probe-bnc)

Kind regards

Hi Scoop,

Yes you would be able to use the current clamp (if you zero out any offset) as long as you get it calibrated on a regular basis (we usually recommend annually to start with, until you become familiar with the period of time that you can use it for before the readings start to become inaccurate).

Regards,
