3 phase power measurement with 4824

Post by vivek ladva »

Hello Sir,

I want to measure three phase power measurement with pico 4824. I want to use it as altenate model of Fluke 435 series 2 power quality analyzer.
https://dam-assets.fluke.com/s3fs-publi ... NG_D_W.PDF

Please check the datasheet of fluke 435 series 2 above....i want all these mesurement with pico 4824 with adding math channel in picoscope 6....Mainly i want 3 phase power, Voltage , current , thd value & percentage of voltage & current, apparent power , transient, energy calculation...

Can we do all or some of these measurement with 4824? If yes then Please guide us for adding math channel in software.

Hi Vivek,
Were you successful in measuring the power using 4824?
Thanks
Nema

Hi Nema, DwightG, Vivek and Martyn,

I am working on some new options to develop on the 4824. Do you have some work done on this and can we patch them?

Thank you

Hi Everyone,

We are trying to cover as much as we can both on the forum, and on our help desk. However, unfortunately, the working from home 'new normal' seems to have created a lot more users making use of the opportunity to resolve some outstanding issues, experiment with ideas, or just learn some things, on PicoScopes and Loggers. This means that we are having to prioritise 'getting to respond to more people' over 'working on more detailed projects', of which creating Math Channels for 3-phase power measurement applications is more of a project than an answer. So please bear with us while we circle back around to it in the near future.

Regards,

Gerry

Hi Hanane, I was just asking out of curiosity. I actually have recently purchased use a 4444 which I intend to use for all sorts regarding 3 phase power.

the 4444 has only 4 channels for good power quality analyze you need at least 6 channels preferred 7 if you want to analyze the null wire also.

with the 4444 you can do max 2 ch at the same time and no null analyze.

Advantage of the 4444 is the probes are powered from the scope and not from battery's.

Does that not depend exactly what you are measuring?

If you are only interested in a source voltage then you need 3, 4 if star connected.
If you are only interested in a source current then you need 3, 4 if star connected.
If you are interested in both a source voltage and a source current only then you need more surely?

Yes but if you want power quality or even simple power you need current and voltage.

Again, it depends what you are measuring. I'm wondering if you are not using the word, 'quality' as I am.
I do single phase, three phase and DC.

I've been wondering if PicoScope 6 or 7 will support two 4444s as I might buy another but have had no feedback yet.

We have no plans for allowing two or more scopes to be controlled from the same instance of the software.

Hi again Gerry, on the back of this I'm thinking of other ways to use more than one scope on one computer and have thought that maybe;
  • Use the unit(s) in virtual machines. Trouble with this approach is the amount of overhead that comes with using such an application. If you have tried it how did you find CPU and memory usage?
    Run two instances of the software and use USB enumeration to ensure that each device connects with the correct instance of PicoScope. Certainly running two instances appears to be possible......
I don't have two Picoscopes otherwise I'd check it myself.

You can run two or more instances of the software with each instance connected to it's own scope, I regularly do this and they don't need to be in virtual machines.
