Summary of Data Provided in Vista
The standard set of Vista diagrams included with WinPM.Net display a variety of
data measured by the factory-configured meter. Some of the diagrams include
grouping windows that display additional data. The following section
summarizes the data, and interactive control functions provided.
Real-Time Measurements
The Real-Time diagram includes a simple power system illustration that shows
various real-time parameters. The diagram also includes links to a min/max
parameter display. The measurements you see in Vista depend on the Volts Mode
setting in your Power Meter module; here are some you may see:
Line-to-neutral voltages, line-to-line voltages, average L-N and L-L voltages and
voltage unbalance level
Phase currents and average current, or total current
Phase kW, total kW, kVAR and kVA
Frequency and signed power factor
Min/max display of each of the above parameters
All logged meter events
Trend logs of voltage, current, power, frequency and power factor
Long-term Min/Max
Double-click the Long-term Min/Max object to see a Vista grouping window
showing min/max values for line-to-line and line-to-neutral voltages, voltage
unbalance, phase currents, power values (kVA, kVAR and kW), frequency, and
power factor. Level 3 WinPM.Net authority is required to reset the min/max
values.
To return to the real-time diagram, use the button on the Vista toolbar; or use
the File pulldown and select Up One Level.
Min/max values are valid from the time the meter was powered up, or valid from
the time the last reset was performed.
Historic Data Logging Enable
The Log Server must be running to view historical data. Historic data logging is
enabled by default. Level 3 WinPM.Net authority is required to use the enable
control object. The control object indicates the logging enable status: the switch is
in the up position (1) when logging is enabled, and down (0) when logging is
disabled.
Power Quality Data
The Power Quality diagram shows voltage disturbance and harmonics details. The
voltage disturbance display counts sag/swell and transient events, and provides
links to a sequence-of-events log and a CBEMA plot. The diagram includes a
trigger for manual waveform recording, and control objects for enabling/disabling
power quality event recording.
