In the grand scheme of things, is a 1.5-2.5A phantom load something outrageous? I know that ZERO is the goal but I was wondering if this is on the normal side or not?
Good point.....hence, 'how' the current is being measured comes into play.That could be mostly reactive power, if the only loads are transformers and power supplies for things. The actual real power may be lower.
A clamp on ammeter only measures current, not power factor (since an in-phase voltage signal is needed for that, too). So a "kill-a-watt" type meter is actually what's needed to distinguish between real power and reactive power.Good point.....hence, 'how' the current is being measured comes into play.
mp....I'm assuming a good clamp on that is RMS would be the most accurate....right? If the OP was using one of those "Kilowatt" meter setups...I could see some error taking place...
