I'm currently working on a bachelor thesis. I took RMS values of harmonic currents from electrical appliances from a standard and would like to theoretically determine them using an office sub-distribution. Can you add them up for each outer conductor?
For example 10 laptops and 5 lights on L1, may calculate as follows?
Then 10 * harmonic current of the laptops + 5 * harmonic current of the light ones = harmonic current of the outer conductors L1?
That is a category too high for my education. But I really know one thing. If 10 devices have the same harmonic, that doesn't mean that you can add the vibrations. Because the vibrations are not synchronized. So it is theoretically even possible that 2 devices cancel each other out. So the calculation has to be different. You have learned some things in advance, what approaches do you have on this topic?
Thank you very much for the help! That makes sense what you meant, since every device has a different phase position and even a different amplitude.
I only have total harmonic currents of the respective devices.
