I am doing an energy audit for a plastic manufacturing company for my final year university project.The company runs on 3 phase and has a large variety of different machinery (blow molders, injection molders, compressors, refrigerators etc) I am required to measure each component and determine how much is contributed to the monthly electricity bill. What is the best way to do this? Is there any pieces of equipment I can use (such as something similar to the kill-a-watt) which can attach to the machine and measure kW usage?The machines run on demand so therefore taking an average from the specifications would be too inaccurate.NEED SOME HELP PLEASE :(
If it runs on demand, whatever you put down will be correct. Let them prove you wrong! Or you could guestimate how long they are used each day and take the nameplate power rating off the machine, then do the math.
