3.5.7.1 Power flow meters
The power flow meters show the present value, as well as the
minimum and maximum value, for each parameter. Click on the small
button between the min/max meters to reset the min/max values.
All of the meters are calculated from phase-locked, 128-sample-
per
-cycle data. The meters are updated once per second - if your
computer is unable to work quickly enough, a warning message will
appear, and you will need to find a more powerful computer. The phase-
locking takes place on the L1-N voltage channel (or the L1-PE channel
for power systems that do not have a neutral).
kiloWatt meter - The true power flowing into the Equipment Under
T
est, regardless of the number of phases, unbalance, power factor, etc.
kiloVoltAmperes - The product of the true RMS voltage and true
RMS current on each phase.
kiloVoltAmperesReactive - The geometric difference between the
k
W meter and the kVA meter. This form of kVAR meter includes
harmonic currents (and harmonic voltages, too, if present).
Power Factor - This is the true power factor, not the cosine of the
angle between voltage and current. It is the ratio of kW to kVA. For
displacement power factor, take the cosine of the Degrees meter.
kiloWattHours - The integration of the kW meter over time. You
