Nah, that was my best shot. . .Could you please give a practical example that I'd really measure negative active power on a certain load?
If AP = V*I * PF, where V*I >=0, then AP < 0 if and only if PF < 0.Don't really understand your question. Where have you found the term "negative active power"? Are you referring to a "negative power factor"?
SO any load would give possitive active power?The only thing that makes sense is a generator.
Negative active power is when the 'load' is an electrical generator.
If the power factor is negative then the average power is flowing the wrong way. As Sceadwian says, the load is a generator (or at least something capable of supplying power).If AP = V*I * PF, where V*I >=0, then AP < 0 if and only if PF < 0.
Didnt think i'd need to explain it.
