Hey guys, For this project I need an electrical engineer who's proficient with analysing electrical data with a special focus to Power Quality. I will provide you with given data sets for 4 different locations (such as aluminium manufacturers, a hospital and a municipal administration). Those will be 10-Min-Values of both Current and Voltage for L1, L2 and L3 and for each of them the harmonics and interharmonic oscillations (1st to 50th). According to that I will give you all graphs for both the harmonics and interharmonics (V and A) as well as a bar chart of the harmonics relating to the threshold levels of the commonly used standards (DIN EN 50160, 61000-2-2, 61000-2-4 and 61000-2-12). Now I'm asking you to for a critical analysation of the charts, to identify potential disruptions and possible solutions / suggestions for properly dealing with them, according to the mentioned standards and locations. I won't necessarily need a concrete formulation/essay from your side, but precise key points with some notes in the charts or set of data. Any further information will be given via private message. Many thanks in advance!

Hello there. I have a PhD in electrical engineering and have previously dealt with power quality analysis using Fluke Power quality analyzer 435. We performed measurements and analysis on several sites in Croatia. If you send me some of the figures needing analysis I can study them and determine whether or not I can help you. And determine the right price based on the workload naturally. Some of my references: [login to view URL]

I am an electrical engineer specialized in renewable energy engineering so i had to design filters to filter out high order harmonics coming out of power electronic devices. I have also modeled and simulated the western Alexandrian distribution network.
