Hi,
I am wondering how can I know exactly if I am in my facility and using a harmonic analyzer, if the harmonic levels I am measuring is coming only from this facility or from a neighbour sharing the same PCC( point of common coupling)? Should I power off my facility and start measure the harmonics levels ?
What is I knew this amount that my neighbour is supplying to my facility, should I subtract the THD_I and THD_V that comes of his part from the THD_I and THD_V when I make the harmonics measurement when my facility is powered on (which I assume will be his and my harmonic levels), so I know my harmonics levels?
