Energy Platform offers a graphical and easy to navigate display of event list and trend
data. The firmware architecture of the Energy Platform is designed to engage in various
stages of acquisition, communication, and visualization of event list and journalled
data.
Event List: Event List displays a summary of all captured events in the order that they
occurred. Energy Platform is able to record three types of events namely sag, swell or
aggregate snapshot. A sag or swell event is detected when the rms threshold limits are
exceeded by +/- 10% of the nominal input. Aggregate snapshot is a timed snapshot for
which a trend plot can be viewed over a user selected time interval. For each type of
event, the min and max values and time stamp are displayed for analysis.
Trend: A trend is a graph of the value of one parameter and channel over time. Trends
aim to show a macro view interface of timespan, trigger conditions, and channels of
waveforms and rms that were recorded. Users can zoom in on trends for a more
detailed view.
View data icons
The Events and Trend icons are used to view event data. Both icons are accessible at
the Home page.
Event data becomes available while the instrument is monitoring or by loading a
previously saved file from the data card. Otherwise, a status message appears
indicating that there are no event data available to view.
The Trend button displays time plots or trend visualizations of journalled data. The
parameters to plot consist of journal entries under the Journal Limit Setup (see pages
6-10 to 6-11). The Trend screen can display up to four plots, with a maximum of two
parameters per plot. One parameter can have multiple channels to plot. Users have the
option to enable/disable plot display, where display area will resize according to the
number of plots enabled for display. The Trend screen also features a Zoom box, where
users can expand or narrow the zoomed area via touch and drag. Users can select the
trend coordinates to view in detail.
