electrical power system

How can I analyze 3 phase 230V electrical power dataset for power quality issues? by pq-analysis
faq1630-2122
Posted: 23 Mar 21

Dear experts,
Can anyone help me with analysis of dataset for 3 phase power system with 230 v within 5 minutes?
The dataset contains colomns of date/time, voltages, frequencies and some other parameter I don't realize, but it is a bit challanging for me to plot it like a signal such as y=sin(2*pi*f*t) in Matlab. Additionally, wonder how to analyze three phase system. I highly appreciate your kind help in this regard.
