Summary of Data Provided in Vista
The standard set of Vista diagrams included with ION Enterprise 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.
Volts/Amps
The Volts/Amps diagram includes a simple power system illustration that shows
various real-time parameters including: Line-to-neutral, line-to-line, average line-
to-neutral, and line-to-line voltages, and voltage unbalance level.
The diagram also includes links to a min/max parameter display, the meter’s event
log, and various historical data logs. A control object is provided for disabling/
enabling historic data.
Historic Data Logging Enable
◆ The Log Server must be running to view historical data.
◆ Historic data logging is enabled by default.
◆ 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.
Long-Term Min/Max Measurements
Click the Long-Term Min/Max object in the Volts/Amps diagram to see the Long-
Term Min/Max Measurements window. It displays min/max values for line-to-line
and line-to-neutral voltages, power factor, and frequency. Min/max values can be
reset with the Min/Max Reset Object. All min/max values are valid from the time
the last reset was performed.
Power Quality
The Power Quality diagram shows voltage disturbance and harmonics details. For
an ION 7600 meter, these details are on the Basic Overview tab of the Power Quality
diagram. The details include:
◆ Running total of sag/swell events
◆ Running total of transient events (ION 7600 only)
N OTE
The ION 7600 features dual waveform capture: Sags are recorded at 32 samples x 54 cycles. Transients
waveform capture at 256 samples x 7 cycles.
◆ ITI (CBEMA) plot of power quality events (Log Server must be running)
◆ Captured waveforms & sequence-of-events log (Log Server must be running)
◆ Phase voltage and current THD as a percentage of phase measurements
◆ Min/max display of phase voltage and current THD
◆ Trend logs of voltage THD, current THD, and current K-factor
