emonlib to measure power factor of inductive and capacitive reactances

Submitted by itauty on Mon, 23/11/2015 - 16:48

I am doing a mini project to measure the 3 phase Alternator Synchronous Generator 220/120 v ( voltage, current , power factor, real power) for electrical laboratories practices .using the method of energy measuring with arduino mega, transformers 220/9v and current transformer sensors of stc300-30  can i se emolib ? i will connect the capacitive reactance and inductive reactance and resistance to the alternator

EmonLib can measure real power and apparent power. Power factor is the ratio (real power) / (apparent power), therefore you can measure power factor, but you do not know whether it is leading or lagging, because the reactive component of current is not available to be measured.
