NOVAR 2600 Operating Manual
5. Meter Block
5.1 Basic Functions
The meter block - universal three-phase meter - is key part of the instrument.
All of usual electric quantities like line-to-line and phase voltages, currents, active, reactive and
apparent powers, power factors, voltage and current THDs and harmonic components, active and
reactive energy, average power maximums, frequency etc. are evaluated. Furthermore, temperature is
measured with built-in sensor. Optionally, the second temperature can be measured with an external
Pt100 sensor at appropriate instrument models.
The instruments are fitted with inputs for connection of three voltage signals, three fully isolated
current signals ( for use with external CTs with 5 A
AC
or 1 A
AC
nominal secondary current ) and
separate AC/DC power supply input. They can be used in both low voltage and high voltage power
grids.
The instruments feature three-rate tariff four-quadrant electricity meter with maximum average active
power ( maximum demand ) registration. Advanced models store all results for actual and last month
too and a separate archive dedicated for automated meter readings can record actual status in
preselected intervals.
Optionally, the instruments can be equipped with battery backed real time circuit, additional memory
for datalogging, RS-485/Ethernet and USB communication interfaces, forming powerful network
analyzer.
Basic specifications of the instrument can be set up by using the inbuilt keyboard and the display.
Therefore the instrument can be used as a multifunction panel-mounting measuring instrument without
computer application.
With the ENVIS program supplied as standard you can, via any of communication link, adjust the
instrument and transfer recorded data. In addition to the instrument adjustment, ENVIS program
allows you to display, view and archive the measured courses in the graphic form, as well as a
number of other features.
5.2 Meter Block Manipulation and Setting
5.2.1 Data Area – Status Bar - Toolbar
Instrument's screen consists of two parts : a data area and a toll bar area .
The toolbar determines function of individual buttons and changes dynamically by a context.
In special cases a flashing indicator can appear at upper right corner of the data area. It indicates
following cases :
