NOVAR 2600 Operating Manual
The actual data group comprises other actual data presentations that are
accessible with the
button - so called actual data display mode
switch . When pressed, a pull up menu rolls over the display temporary.
By multiple pressing of the button a desired actual data subgroup can be
selected and displayed :
• Actual values – values of all measured
quantities in numeric format.
• Average values – average values of main
measured quantities including their maximums & minimums. For detailed description see
chapter
Display Average Values Evaluation and Aggregation further below.
• Waveforms – actual wave shapes of all measured voltages and currents.
•
Harmonics – actual harmonic components of all voltage and current signals
in both numeric and graphic ( histogram ) formats. For detailed description see chapter
Harmonics and THD Presentation.
• Phasors – diagrams of voltage and current fundamental harmonic phasors. A
phase sequence can be checked here too (indicated as 1-2-3 or 1-3-2 ).
With the last option of the display mode switch – V,A,W↔% – voltage, current and power quantities
expression can be switched between basic units and percent relative to preset nominal voltage U
NOM
and nominal power P
NOM .
5.2.2.2 Daily and Weekly Graphs
This option is supported by instrument models equipped with RTC & additional memory
only.
A one-week history of main measured quantities ( such as voltages, currents, powers and power
factors ) is registered in the instrument's memory cyclic buffer. Individual courses can be displayed for
rough check ( for detailed check at a PC a main archive is intended, see appropriate chapters further
below ).
With the button, either whole week or specified day of the passed
week can be selected – on the graph, the day is identified with its shortcut
( Mo = Monday, for example ). Excluding of seven passed days, so called
S-day and M-day can be viewed too.
The S-day is a predefined day of year. The S-day record refreshes once
per year only. The M-day is the day when maximum 15-minute average
value of
ΣI occurred. Both the S-day date can be preset and the M-day
record can be cleared via communication link with ENVIS program only.
For details see the ENVIS program manual.
With the ►button desired group of quantities can be selected. For listing
through the selected group, use the ▲and ▼buttons.
5.2.2.3 Electricity Meter Data Group
The electricity meter group comprises registered electric energy and maximum active
power demand values. For detailed explanation see chapter
Energy Data Presentation
further below.
