ITI / CBEMA power curve analysis

Hi, slightly off-topic question, but I do have a green eye and an emon, neither installed, todo list...

I do have a Fluke VR1700 power quality analyzer, and I've recorded more than a year's data, weekly dumps, and I'm looking for a way to combine the weekly reports, and analyze the data.

My specific intent is to get the power company to do something about the low voltage, and frequent dips, sending my UPS on battery power, and making my coffee machine unhappy.

I can produce weekly reports using the Fluke PowerLog software, but I am unable to combine data, and produce reports on larger sets of data.

Any ideas on where to get software, or formulas for excel/matlab/etc. to analyze the data?

 

Thanks

P.
