Table 4.5 displays the Power Metering information
provided by the Powermonitor II. The gray scale
indicates which parameters are available through the
Display Module, the Smart Communication Card, or
both.
The power quantities (kW, kWH, kVAR, kVARH,
and power factor) measured by the Powermonitor II
are four-quadrant measurements. This allows the user
to individually determine the magnitude and
direction of both the real power flow and the reactive
power flow. Figure 4.3 indicates the relationship
between these quantities and the numeric signs used
by the Powermonitor II to convey the information.
