    Harmonic Amplification Calculation

    I should have clarified in the original post: 3A 13th harmonic current is a load current measured on the secondary side with no PF caps in system. Vs = 600V. Lets make up a load current harmonic spectrum for example: I1 = 100A, I5 = 18A, I7 = 13A I11 = 5A I13 = 3A I made up this example...

    Harmonic Amplification Calculation

    Thank you 7anoter4 for your detailed response, this was helpful. I haven't had a chance to work through the calculation yet but will once you update it. RB.

    Harmonic Amplification Calculation

    Hello all, I'm familiar with calculating resonance for adding PF correction capacitors in industrial plants. My question is, knowing what the resonant frequency will be, and knowing the existing harmonic currents, how do I manually predict the actual amplification factor on these currents that...

    The Electrical Harmonizer

    Sorry, I was out of town for a few days. A few loose ends to tie up here: 1. Lighting design is pretty scientific, but that all goes out the window once the system is in operation for a while. Major variables come into play that affect light levels such as dust/dirt on lens, oxidation of...

    The Electrical Harmonizer

    Folks, I am new around here, and this topic caught my eye while browsing. A little clarification is in order based on my experience with it: I work for an electric utility. Some utilco's lower voltage as a peak demand and/or energy saving measure. We don't, but we have done tests to understand...

    Grounding Mod

    Hi all, I'm new here and this is my first post... woohoo! Anyway, my question is whether anyone is aware of proven benefits to supplementing the engine ground in certain vehicles. I'm a member of a Subaru owners forum and many there claim that on the turbocharged WRX, adding additional ground...
