Power Calculation Modes
The power calculation mode option allows you to change the
method for calculating reactive and apparent powers in
presence of high harmonics. The options work as follows:
1. When the reactive power calculation mode is selected,
active and reactive powers are measured directly and
apparent power is calculated as:
22
QPS
This mode is recommended for electrical networks with low
harmonic distortion, commonly with THD < 5% for volts, and
THD < 10% for currents. In networks with high harmonics, the
following method is preferable.
2. When the non-active power calculation mode is selected,
active power is measured directly, apparent power is taken as
product S = V x I, where V and I are the RMS volts and amps,
and reactive power (called non-active power) is calculated as:
22
PSN
Local Settings
This setup allows you to specify your time zone and daylight
savings time options.
To configure the time zone options for your device, select the
device site from the list box on the PAS toolbar, select General
Setup from the Meter Setup menu, and then click on the Local
Settings tab.
