Power, energy and power factor  

Power and the PQ coordinate system  

The meter uses the values of real power (P) and reactive power (Q) on the PQ 
coordinate system to calculate apparent power  

Power flow  

Positive power flow P(+) and Q(+) means power is flowing from the power source 
towards the load. Negative power flow P(-) and Q(-) means power is flowing from 
the load towards the power source.  

Energy delivered (imported) / energy received (exported)  

The meter interprets energy delivered (imported) or received (exported) according 
to the direction of real power (P) flow. Energy delivered (imported) means positive 
real power flow (+P) and energy received (exported) means negative real power flow 
(-P).  

Power factor (PF)  

Power factor (PF) is the ratio of real power (P) to apparent power (S), and is a 
number between 0 and 1. An ideal, purely resistive load has no reactive 
components, so its power factor is one (PF = 1, or unity power factor). A purely 
inductive or capacitive load no resistive components, so its power factor is zero (PF 
= 0).    

 

 

 

 

True PF and displacement PF  

The meter supports true power factor and displacement power factor values:  

•

 

True power factor includes harmonic content (PF).  

•

 

Displacement power factor only considers the fundamental frequency (DPF).  

PF sign convention  

The meter shows positive or negative power factor according to IEC standards.  

PF sign in IEC mode  

The meter correlates power factor sign (PF sign) with the direction of real power (P) 
flow.  

•

 

For positive real power (+P), the PF sign is positive (+).  

•

 

For negative real power (-P), the PF sign is negative (-).
