GridVis® software
An elementary module for energy management and
power quality monitoring systems
In the field of energy management it is
very important to be able to evaluate and
process data measured for both energy
usage and power quality. It should be
possible to document all important data
measured without interruption, in order
to determine reasons for production
problems, failures or quality deficiencies.
For example, time stamped data for
harmonics, voltage fluctuations or blackouts facilitate the identification of root
causes of possible production problems.
With timely identification of poor power
quality it is possible to take steps to
avoid the increased wear or destruction
of electrical distribution controls and
operating equipment and even reduce the
risk of fire. Through the analysis of load
profiles and electrical loads it is possible
to implement measures to improve energy
efficiency. Within the framework of energy
management, targets can be defined for
energy consumption, CO2 emissions and
energy costs. The new standard ISO 50001
has formulated a suitable framework
of conditions for an operational energy
management system.
When the energy management system
has been chosen, Janitza software and
hardware components provide the ability
for you to view and document your energy
Energy management systems help companies to optimise the use of energy –
from purchasing right through to energy
consumption – on a systematic, economical
and ecological basis.

Generic modbus devices
(Modbus RTU, Modbus TCP/IP)
GridVis® offers a range of options for
the integration of 3rd party devices. The
“generic modbus“ function provides a
simple integration option for “non-Janitza
measurement devices“ via Modbus RTU
or Modbus TCP/IP. The external devices
must support the modbus RTU protocol.
The data formats must also comply with
the modbus recommendation or with the
available formats in GridVis®. The Modbus
ASCII protocol is not supported by GridVis®.
The connection of external devices is
achieved with a Modbus master UMG, via
its RS485 connection or the value can be
read out directly with GridVis® via Modbus
TCP/IP, using Ethernet.
The external devices are integrated
through profiles and managed in GridVis®
as templates, which can subsequently be
used multiple times per project. It is also
possible to export a template. Profiles are
created and edited directly in GridVis®.
The measured values read out from the
external devices can be used in the topology view and in the GridVis® virtual devices.
When using the GridVis®-Service version
it is also possible to store the measured
values online with mean value formulation.
The measured values are cyclically
polled here. It is possible to control the
communication via an integrated statistics

Device configuration
Setting parameters and configuration of measurement devices
The user-friendly GridVis® software allows
integration, and configuration of UMG measurement devices, their parameters can be
set and comprehensive settings for custom
solutions created.
Connection to time servers (NTP synchronisation) enables time based synchronisation
of the measurement values. In this way it
is possible to reconcile events at various
measurement points simultaneously and
identify these accordingly.
Trigger values for the measurement of
events and transients can be defined
as well as the measurement values for
storage together with storage intervals. It is
possible to program the limit values for the
monitoring function of the digital outputs,
via comparators or determine pulse values
for the digital inputs or outputs.
It is also possible to capture the readings
of external temperature sensors for the
transformer or ambient temperature.
Grid Visualisation Software
Topology views (visualisation)
The topology view provides a quick
overview of the energy distribution system
with the option of localising grid failures
through a comparison of the individual
measurement points and checking the
defined tolerances at a glance.
Presentation of limit value overruns (e.g.
THD-U too high) as well as input and
output status is also possible. If parameters
are above or below threshold limit values
these can be highlighted by means of a
change in colour.
It is quick and easy to create customerspecific solutions by storing graphic
files (standard format JPG) with circuit
diagrams, production lines or construction
plans and integrating the associated
measurement devices by means of
“dragging and dropping” to their actual
It is possible to call up a device view of
every measurement device on the system
which is online. This view is available
directly via the actual display. Furthermore,
in the case of some device types remote
operation is also possible. All selected
measured data for the devices can be
presented online simultaneously.
Animation in the topology
Hyperlinks in the topology
Animations — such as a change of views
between images — draw attention to
important events. For example, through
value-dependent display of images, a
colour change can be shown when a rated
voltage has been exceeded, a red light can
be activated, or a circuit breaker can be
marked as triggered.
Hyperlinks can also be integrated into the
topology view. This allows linking of the
URL to any website or to other topology
pages. Through these, the user can call
up documents or access calibration
certificates, operation manuals and Excel
evaluations. Even batch jobs or other
programs can be launched by hyperlink.

Online and historical measured values
Online data
Online data comprises all measured values
that are captured by the measurement
devices on a current basis during runtime
and constitute the momentary ACTUAL
GridVis® enables specific logging, reading
and display of online data. The data obtained from various measurement points
is collected, stored, prepared, displayed
and made available. All measured values
are available in the online measurement
mode, either as line graphs or bar charts.
The line graphs are always up-to-date with
the oldest data being omitted dependent
on the measured data quantity setting.
It is possible to set two y scales for the
measured data of two units, e.g. current
and voltage, on a time-synchronous basis.
An arbitrary quantity of measured data
from multiple measurement devices can be
presented on the same graph for each unit.
The colours of the graphs can be selected
and amended on an individual basis.

for energy management considerations
Historical data
The measured values which are stored –
either in the device or read out from the
device and saved to a database – and made
available in accordance with defined rules
and averaging periods are referred to as
historical data. Each stored value is given
a unique time stamp and the respective
device IDs are assigned. The data is
stored in the database by parameter, year,
month and day. The data can therefore be
extracted on a selective basis.
Particularly interesting time frames can
be enlarged with the zoom option and
measured using the measurement function.
GridVis® screen with historical evaluations
Presentation of the data in the form of bar
charts, line graphs or histograms can be
appended and printed out with headings
and comments. The presentation of transients and events also takes place here in
the transients or events browser. The flag
browser offers the option to show missing
measured data over certain periods, as
well as untrustworthy measurement information. For eaxample by analysing
historical data it is possible to show
load profiles, in order to produce precise
requirement analyses for optimised current
supply contracts. It is also possible to carry
out fault analyses by comparing various
parameters with just a few mouse clicks.

Reporting – Power Quality
(EN 50160, EN 61000-2-4, Nequal, IEEE 519, ITIC CBEMA, PQDIF, etc.)
The voltage in our electrical systems today
is far from a pure sinusoidal shape. A wide
range of “power quality distortion” types
such as voltage interruptions, transients,
harmonics, flicker and inrush currents alter
the sinusoidal character of the currents and
therefore also the voltage.
In some instances this results in damage
to operating equipment, which is exposed
to excessive electrical loads and may
exhibit increased thermal losses. A loss
of operating equipment or its restricted
functionality may cause an associated
production failure. A high flicker level
can lead to fatigue and discomfort
of personnel, whose capabilities are

affected. Unacceptably high currents in the
protective earth conductor cause voltages
in radiators, pipes, etc. Increased currents
in underdimensioned neutral lines pose a
significant fire hazard. It is therefore
advantageous to detect power quality
events in a timely manner, and to take
corrective action. GridVis® offers all of
the tools required for this. At the heart
of the system analysis is the reporting
system of the GridVis® software. This offers
confirmation – at a glance – as to whether
the power quality is adequate or not during
the period under review. However, further
tools are also available for analysis of
the supply to help identify root causes of
Grid Visualisation Software
Reporting – Energy management systems
Within the framework of an energy analysis
it is necessary to measure and monitor
important parameters of the electrical
energy supply. The data supplied from
the measurement devices is displayed in
GridVis® online as momentary values or
from the historical values.
The evaluation of this data can take place
via the report generator integrated into
The reports can consolidate a range
of information depending on the
requirements and settings. For example
energy and power-related cost centre
reports can be created. This not only
facilitates the presentation of electrical
energy values from the measurement
devices but also the allows evaluation of
other media (gas, water, etc). Furthermore,
load profile analyses, which are based on
a defined time frame, provide an overview
of peak demand consumption.
The generation of individual reports can
either be automatic via freely definable
schedules or can be started manually
by the user as a printable report or as an
HTML, XML, Excel, Word or PDF file.

Janitza DB
Since GridVis® release # 4.1, the Janitza
database “Janitza DB“ has been in use.
It is specially optimized for GridVis®. This
database can be selected while setting up a
new project and works extremely fast.
Data can be exchanged with other software
platforms, home pages etc. through the
REST interface (see page 22).
Janitza DB is delivered with all editions
of GridVis® to save the user additional
expense. This also applies indirectly to work
time, since no additional installation time is
Note: It is not possible for multiple clients to
access the Janitza DB! Only one computer
or server can connect a GridVis® desktop or
GridVis® service to a single Janitza DB.

Almost every measurement device is
equipped with an integrated data storage
facility. When this memory is read out,
the measured data is backed up to a
database. Apache Derby, MySQL and MS
SQL databases can be selected. In the
case of projects with 5 devices or more we
recommend the use of an SQL database.
The possible installation software versions
are GridVis®-Desktop, GridVis®-Service and
a mix of GridVis®-Desktop / GridVis®-Service.
GridVis®-Desktop can be installed locally
on a desktop or centrally on a virtual
machine. When reading out data from the
measurement devices GridVis® must run
as an open, active program. From here it is
possible to address, read from or configure
devices. All generated data is written to the
database associated with the respective
GridVis® project.
GridVis®-Service functions in the same way
via a system service on a remote server.
As servers are rarely switched off, this
system service can read out data from the
measurement devices on a constant basis
in the background, without GridVis® being
open on a client computer. This type of
service installation can be used by multiple
clients in parallel. The configuration of
devices and projects takes place via the
GridVis®-Desktop program interface. The
rights for the devices are subsequently
handed over to the GridVis®-Service. This
can be configured via a browser. All graphic
and statistical evaluations continue to take
place via the GridVis®-Desktop.
In general it is possible for any number of
GridVis®-Desktop and Service instances to
access one and the same database (with
the exception of Apache Derby). However,
a device, at any one time can be linked only
to one GridVis® or one GridVis®-Service.

Easy data exchange
Due to numerous interfaces and proto-cols
(e.g. Modbus / Profibus / M-Bus), an uncomplicated system connection (energy
management system, PLC, SCADA, GLT) is
In general terms all energy measurement
devices can now be networked with each
other. Communication between GridVis®
and the measurement devices takes place
via Modbus RTU or Modbus TCP. Measured data is read out automatically via
a field bus and made available for further
use via a central data server.
To keep installation costs low (e.g. peripherals for field buses), Ethernet TCP/
IP is used increasingly frequently as the
backbone of the data communication.
Through connection to an existing Ethernet architecture, fast, cost-optimised and
reliable communication is usually guaranteed.
Janitza systems essentially offer an
extremely open architecture so the Modbus addresses can be accessed directly

The virtual measurement device calculates the total consumption in the supply line
“Virtual measurement devices” are available with GridVis® for the purpose of
mathematical calculations.
Through the addition of various measurement points it is possible to consolidate entire areas. This function is a
useful application in particular for cost
centre management.
A further application area is the calculation
of key figures. For example, in order to
evaluate the energy efficiency in computer
centres the calculation of power usage
effectiveness (PUE) would be useful. In such
calculations the total energy consumed
in the computer centre is presented in
comparison to the energy consumption of
the computers.
Virtual measurement devices can calculate
the momentary as well as the historical
value where the pertinent basic data exists.
The following operations are possible:
Addition, division, multiplication and
With the aid of numerical constants it
is also possible to calculate percentage
values. A major advantage of the GridVis®
virtual measurement devices is that no
additional measured values are stored
in the database. Virtual measurement
devices carry out calculations during the
GridVis® runtime. For the purpose of the
graphic display it gains direct access to
the source data of the device, calculates
the value and displays this in the graphic.
Up-to-date measured values from virtual
measurement devices are also calculated
during the GridVis® runtime.
A range of target data points are available for calculations with non-electrical
media. A data logger such as ProData can
serve here as a source of these media.
The integration of external devices via the
generic modbus option of GridVis® is also
possible (it may be necessary to carry out an
integration test in this case). It is optionally
possible to process the measured values
of global variables from the measurement
devices in the virtual devices.

Analysis of power quality
In parallel with energy monitoring GridVis®
also places a principle focus on monitoring
the power quality.
The threshold values are issued to the
measurement device via GridVis®. System
events such as overvoltage, undervoltage,
short-term interruptions, overcurrent and
transients are accordingly automatically
logged with preset cycles before and after
the event. Preconfigured parameter lists
are available for logging in accordance with
EN 50160 and EN 61000-2-4. The power
quality is negatively affected by the
increasing number of non-linear loads. On
the other hand “mains feedback”, caused
by the trend towards decentralised energy
generation and the reduced mains short
circuit power frequently associated with it,
has a greater effect – mains feedback!
Continuity of supply, system assurance, supply reliability, service and in particular power quality are of primary importance to the
GridVis® delivers a range of features for the analysis of power quality:
 Oscilloscope function of the live values
of numerous power quality parameters

Events and transients
The costs of voltage dips (sags) and
transients are commonly underestimated!
Events refer to short-term voltage peaks,
dips or short-term interruptions, e.g. due
to bird strike or a short circuit caused by
construction works.
Voltage dips and short-term interruptions
can cause major problems. Especially
in production and in critical processes,
this can result in quality problems and
production downtimes. The financial effects of such voltage drips are commonly
Short-term interruptions usually incur immediate, often with considerable costs.
It is therefore important to identify and
analyse the cause of such power quality
fluctuations with user-friendly tools.
With the event and transients browser,
GridVis® offers helpful tools through
which to ascertain and classify diverse
events on the supply system In both
procedures the list view reports on the
event data. From the list it is possible to
call up the respective graph, zoom in or
out, print it or export it to a PDF or CSV
file. GridVis® optimally utilizes the device
capacity. As such, events from a duration
of 10 ms and transients from 50 µs can
be reliably logged and further processed.

drops with date and time stamp, length and depth of the voltage

Users‘ individual rights are compiled in
predefined roles (groups of rights). Roles
(groups of rights) are cumulative, i.e. the
rights of users from various roles are
added together. If a project is protected
by user administration, login is required
for access. In GridVis® 4.0 and above, all

Alarm management
Intelligent alarm management system
Alarms are defined as events that require
an immediate reaction from the energy
manager responsible or from the operation
supervisor. Systematic management of
alarms is indispensable in monitoring
energy and power quality. For this,
GridVis® #4.2 and above (Service edition)
offers powerful alarm management for
monitoring all measurement parameters
of UMG measuring devices. It allows rapid,
reliable signalling of fault conditions (e.g.
disconnected communications equipment
measurement data servers, measured value
exceedances, etc.)
No reports are lost
Effective monitoring options
The GridVis® alarm management system
offers user-friendly administration of
employees and supervisors. This includes
acknowledgement functions and escalation
management. It means that if there is no
response, another employee is informed.
If the second person does not react, a
third is informed, etc. Their order can be
configured individually. A logbook function
provides the user with a list of open and
acknowledged alarms. Sorting and filter
functions ease evaluation.
With the GridVis® alarm management
system, both current (online) and historical
threshold values can be monitored (absolute
data, consumption data over time, etc.).
Monitoring can even include availability of
measuring points (UMGs) and the last time
data were synchronized.
Immediate, fully automatic fault reporting
can be transmitted through various channels
to a multitude of different recipients.
Various options allow customization to the
operator‘s needs.
If there is an alarm, a number of actions can
be triggered: Staring a program (such as text
message, Twitter, Modbus address, etc.),
sending e-mails (text, alarm information),
manual and automatic acknowledgement
functions, pop-up windows and sound.

GridVis® into other systems. GridVis® has
very open system architecture that allows
measurement data to be integrated through
various paths into external software.
The REST interface is extremely useful
for integration of measurement data
visualizations and home pages. This allows
fast, easy calculation of energy data and
further processing of data, such as for
creating indicators.
Note: The REST interface is available only
with the GridVis® Service edition.
The result of the URL query is page
content in JSON/XML with the requested
measurement values or information. This
is supported both for online and historical
