    How Can I Build a Low Cost Harmonics Generator for 120v 60hz Power Lines?

    Great, schip666...Feeding a square wave to a Low pass filter would do the trick...Depending on the filter cutoff frequency I can decide what harmonics should pass... Thanks

    How Can I Build a Low Cost Harmonics Generator for 120v 60hz Power Lines?

    Thanks Berkeman, Yes Berkeman you are right about the harmonics. The relay(SEL-751) is capable of measuring the rms voltage (including the fundamental frequency and higher order harmonics in the signal). Anyways, the relay is not really important at this stage. I have a basic knowledge about...

    How Can I Build a Low Cost Harmonics Generator for 120v 60hz Power Lines?

    Low Cost "Harmonics Generator" Hi, Thanks in advance. I noticed how good is this forum so I decided to share my thoughts with you about the following. If possible, I need some ideas from you guys to build a low cost circuit to generate only 2nd an 3rd harmonics for a 120v 60hz sinewave input...
