Is there anything in particular you’d like me to look at/check?
Looking at your Github page with a view to downloading this version, I noticed this:
“CT values are interpolated between the appropriate voltage samples.”
Do your really mean this? We’ve always interpolated between the voltage samples because the interpolation routine is most accurate with a pure sinusoid – and voltage is likely to be closer to this than the current. I hate to think what interpolating between samples of this current wave to generate a time-shifted exact replica would turn out like:
or this most distorted channel made up of a boat load of CFLs
