I didn't know where to put this post, either here or in Tech. Reference.

Anyhoot, I am looking for info on test equipment. I want to start looking at all three phases of power at once. I want to start looking at noise on systems and do some power quality stuff. I thought of a 3 or 4 channel O scope, but was wondering if any one had better ideas.I own a graphical meter (fluke 867b).But it is only single channel. Also own a (fluke 39) power anylizer to do power factor, but it is limited too. In short, I didn't know where I wanted to go with this at the time I purchased these.

What I would like to do is Log the voltage, current draw, for single and 3 phase systems, as well as see noise if it is present. It would be great if something could handle a whole 42 circuit panel at once, but the best I can find only does one 3 phase circuit at a time.

Any clues as a direction for me?

Dnk... Try these two units they are pretty well adaptable to most needs. These are a bit newer than ours.The software is probably better and the nice part is they can be left alone as a data logger or used as a piece of test equipment.The first one is for 60HZ and the second for 50HZ.

Dnk, take a look at www.dranetz-bmi.com The PowerXplorer PX5 Power Quality Analyzer will do all you ask and more. It is pricey but does work very good. All data is recorded on compact flash memory. They have other models available but I have not used them.
