The phase lag angles of all phases can be viewed simultaneously, using the checkout connections
feature. The final screen of that 6 step process displays these angles in degrees of lag.
Power Factor and Phase Measurements in PSM
The consumption data log can record maximum, minimum, and average true power factor for each
phase and for total power for each logging period. The summary values at the top of the screen are the
maximum, minimum, and average of all the values shown on the screen.
When viewing consumption waveforms, the average true power factor of the waveform is shown at the
top right. If a harmonic analysis is displayed, the true power factor is also listed.
If trending data is being recorded and ATPOL II is operating in phase-phase voltage measurement
mode, the average total true power factor for each second will be displayed and recorded each second.
Phase lag angle is most easily determined by viewing a waveform and then clicking on the phasor
diagram icon. The phase lags of each phase will be listed on the right as well as the phase angle
between the phase 1 voltage and all other signals.
The measurements of true power factor, displacement power factor, and phase lag angle presented on
the ATPOL II can also be displayed in PSM by using the remote control feature.
In addition our Report Generator software will present maximum, minimum, and average true power
factor of each phase and of the total power factor during any one or two intervals of time set by the
user. If two time intervals are chosen, it will report the percent change and the actual change between
the two intervals. For instance, if a comparison report is chosen and TPF
1
is 0.48 during the first
interval and 0.48 during the second interval, then the report would show:

Energy Measurements
The energy consumed is defined as the sum of the true power over time:

measurements are taken every second in units of watts, then the KWH consumed during that second is
3600 / 1000 /


. The energy used over a longer time would be the sum of each of these energy
measurements of each second.
Useful measurements and estimates of energy are:

Real energy consumed

Reactive energy consumed.

Estimated energy consumed per hour

Estimated energy consumed per month

Estimated energy consumed per year
The real energy consumed is the amount of energy actually consumed during a period of time such as
since monitoring started or during a specific week. For instance, if the sum of the KWH of each cycle
totals to 5 KWH after 10 minutes of monitoring, then the energy consumed during the monitoring
