hello guys.
I'm pretty new here and read here on the forum but found no real answer to my future project.
I want to build a 3 phase mains voltage analyzer / monitor and logging. No power consumption or PV monitoring needed.
The idea would be that I measure a couple of days the supply and do a logging/monitoring on a laptop.
Can someone explain me ( step by step ) what I do need ? I have a basic knowledge of electronics.
thanks in advance
Re: 3 phase voltage control and logging
What quantities relating to the mains do you want to measure? As it stands, your question is a bit like "How long is a piece of string?"
Re: 3 phase voltage control and logging
As I understand the question, 3 phase voltage monitoring is very easy. just requires 3 ac transformers and either 1 arduino with diy input circuits or 3 emontx:s. the logging could be done to emoncms.org server.
Its really about what resolution you want. If average over a couple of seconds resolution OK then this method could work. If you need real time monitoring then the logging must be built into arduino and e.g. sdram.
Re: 3 phase voltage control and logging
Petrik, you're assuming that permeke only wants voltage. Commercial analysers measure and log much more than that, harmonic content, frequency, spikes, dropouts, etc, hence my question.

hello.
Yes I need to measure over a 24 hour period. Can be with intervals of let's say 5 minutes.
I wonder if it can be done with arduino and monitoring on a laptop.
