Hi sadu,

sorry for this question, but what is PQ?

Google gives a few hits.

PQ - Power Quality according to here

You need to provide much more information as well as the parameters in order for anyone to provide help.

And please use vowels in your writing.  Unlike Wheel of Fortune, they don't cost anything here, so there is no need to leavy them out.

Oops.  I meant "leave".

Glad you enjoyed it.

I just get tired of reading messages where people type in abbreviations.  It is like they are text messaging rather than communicating in English.  And in my opinion, text messaging was one of the stupidest inventions ever and will lead to the downfall of civilization.

Okay, maybe not the downfall of civilization, but it is still riduculous to see people hovered over their cell phones not paying any attention to the world around them.  If you've got a cell phone, call the person and talk to them, it's much more efficient than typing in meaningless ancronyms on a tiny keyboard!

I work in the power conversion industry and do these types of measurements all the time…

Do you want to just measure power quality or create and measure power quality problems?

What hardware are you using?

Power quality analyzer?

Programmable AC power source?

Fast Transient Generator?

Here is an example of what I do.

To create PQ problems I use a California Instruments AC source set to nominal power for the unit under test. Using Labview I program several transients consisting of fixed and random duration dropouts and surges. I also use a Schaffer Fast Transient Burst Generator to apply high frequency noise bursts directly onto power lines.

For measuring power quality I use a Voltech PM3000A power analyzer and Labview to measure everything from voltage, current, and frequency, to  harmonics and %THD
