7.6. Power and Energy
Power and Energy displays a table with all important power parameters. The related
Trend screen shows the changes over time of all measuring values in the table.
 Table
The table displays power data for each phase and in total: real or active power (kW),
apparent power (kVA, the product of rms voltage and current), reactive power
(kVAR, the reactive component of apparent power caused by phase shift between
AC current and voltage in inductors and capacitors), power factor (TPF, the ratio of
real power to apparent power for the total rms including harmonics), displacement
power factor (DPF, the ratio of real power to apparent power for fundamental), and
the rms values of voltage and current.
A popup table with energy usage by phase and in total can be activated by pressing
【F3 】 –Energy function key. The table shows real energy (kWh), apparent energy
(kVAh) and reactive energy (kVARh). The energy measurement starts when
Power&Energy is started. The readout can be reset with function key F5.
Available function keys:
F3 Access the Energy popup screen.
F4 Access the Trend screen.
F5 Switch between RUN and HOLD.
