Energy Management: the solution
Today, global warming due to the green house effect
is affecting all our lives and the economy. The oil supply may be close to depletion, leading, along with the
geo-political situation, to high final prices. In addition,
after the Japanese earthquake, nuclear power generation has once again shown its weak points, indicating that this energy source may not be the answer.
The Earth needs alternative energy sources, and
very soon, but firstly a rational and conscious use of
the available ones is more than necessary.
Measure, Know, Act and Save
Carlo Gavazzi is one of the first multinationals to understand this situation and foresee its consequences,
providing a comprehensive series of instruments to
measure, analyse, understand and predict the energy
consumption of our customers, thus facilitating savings in terms of money and energy resources.
Nowadays it is not admissible nor acceptable to pay
for the energy measured by non-certified meters, or
to provide energy paid at a flat rate, or to be unaware
of one’s own consumption, or to ignore the different
coast of each production step or of each department
of a company.

Fiscal Metering for cost sharing
Deregulation in the energy market and the constant increase in electrical costs, also in countries where they were
traditionally very low, have resulted in a fast growing demand for fiscal metering.
A flat rate for the energy consumption of each shop in a
shopping mall, for each tenant in a residential building, for
each boat in a marina, or even for each caravan in a campsite, has now become non-acceptable. Either the provider
or the user would lose money, so both of them want a “certified” value of the energy actually used.
In 2006 the European Union released a Measuring Directive (called MID), dealing with a number of metering issues,
from energy to water, from taximeters to exhaust gas meters, with the aim to provide common rules for metering
within the European territory.
Certified measurements for a non-disputable bill
Carlo Gavazzi provides MID certification with a wide range
of energy meters covering single or 3-phase systems, without any communication or including pulsating output or serial port, for DIN-rail and/or panel mounting.
The success of this series has led to the implementation
of MID certification being applied within our laboratory in
Belluno, Italy. This is one of the first internal labs in Italy,
improving our service to the customers.
Main advantages:
• Wide range of certified solutions
• The parameters can be programmed once the unit is installed: no need to know in advance all the installation details before ordering
• Terminal covers included for easy and quick final sealing

Power quality analysis for full control
In large and heavy industries as well as in airports, hospitals or installations such as water treatment or distribution plants, it is of fundamental importance to have powerful control of the mains, since medium voltage systems
and very high currents are involved. Because of the type of
loads, a low content of harmonics is crucial to let the installation work in a reliable way. Stops in production should be
avoided because they significantly impact on the finances
of the company or on the level and safety of the service.
Therefore, the monitoring of mains and the operation of the
most important loads with local power analyzers and data
logging systems is crucial to allow continuous load control
which, with communication capability, alerts service staff as
soon as an abnormal condition occurs.
The solution proposed by Carlo Gavazzi involves two modular series of power quality analyzers, which can be tailored
according to the particular requirements of each installation, offering many I/O combinations with PLC-like AND/OR
Mains and load are now totally under control
output logic, serial, Ethernet, or optical ports, different protocols (such as Modbus or BacNet), integrated datalogger,
detailed harmonic analysis and multi-tariff management.
All this can be easily integrated into any SCADA or BMS
system or managed by our software solution, PowerSoft.
Advantages of modular system:
• PLUG and PLAY modules common to all models; maximum in-field flexibility.
• Possibility of increasing the number and the kind of outputs according to new application needs without replacement of the instruments in-field.
• Small number of models in-house, with a complete range
of possible combinations at the same time.
• Investment in the instrumentation can be limited to present needs with the possibility of increasing it in the future
for any additional requirements.

WM5 96 is a Smart Power Quality Analyzer powered with ARM technology
which significantly improves signal
processing and communication speed
compared to any other standard analyzer. The superior features of this instrument are the right answer to those
applications where performance and
high accuracy are a MUST. WM5 96
is modular and flexible so it is suitable
for the most demanding applications.
It offers many advantages and solutions:
• Revenue grade and revenue approval to be used also for billing purposes thanks to the 0.2 accuracy class
and the compliance with ANSI/IEEE
C12.20-1998 and CAN3-C17-M84;
• Real cost control: complex and complete tariff management (12 tariffs by
24 time periods/day);
• Extended load or line control with
asymmetry, phase sequence and
phase loss functions: on up to 16 selected variables linkable to up to 16
independent or OR/AND/OR+AND
logic controlled alarms;
• Complete interfacing capability: up
to 12 digital inputs, up to 16 pulse
outputs, up to 8 analogue outputs,
RS232, RS485, or optical communication.
Analysis of power quality and control of electrical parameters
The problems which must frequently occur in electrical systems with inverters and power converters, switching power
supplies for computer and communication systems applications are the following:
• failures on compensation capacitors;
• blowing of capacitor fuses;
• overheating of power supply transformers with a load current below the rated value;
• overheating of motors and frequent failures;
• high neutral conductor currents;
• problems on electronic motor controls.
These are mainly due to the harmonic content of currents
and voltages.
The best solution is WM5 96, which allows continuous monitoring of the harmonic contents (up to the 63rd harmonics)
of currents and voltages, together with all other electrical
parameters.
The control of up to 16 different electrical parameters by
means of alarm set-points with a specific logic (OR/AND)
and automatic recording of up to 10,000 events (alarm, min,
max, digital input status, reset) allows the operator to monitor any anomaly of the installation and of the loads in real
time, so as to promptly decide and plan any maintenance
action, thus avoiding possible damage to the loads and/or
expensive stopping of the machinery.
Easy and fast communication
A front optical communication port based on ANSI C12.18
and Modbus protocols can be used to carry out easy and fast
communication with a PC or laptop. The correct Wm5Soft
software allows the user, through a multi level login procedure, to:
• Read the measurement data and show it as a matrix on the
monitor;
• Program all the parameters to quickly and easily adapt the
instrument to the application needs;
• Download the stored events (alarm, min, max, digital input
status, reset) in an XLS format to easily build up an installation history;
• Recalibrate the instrument, when needed, directly from a
local support;
• Upgrade the instrument firmware, improving its characteristics and thus adding more and more value.

Multi function meters for basic measurement
In the past, simple measuring systems like current-voltagepower and power factor were available to control the mains.
More complex solutions were available as well, but in many
cases these required higher investment. Nowadays more
and more sophisticated machines and loads like computers, switching-mode power supplies and drives are used in
production facilities, thus significantly increasing the complexity of loads and thus of potential problems.
Simple while saving space and money
Carlo Gavazzi can provide different levels of solutions:
• Simple multimeters to replace the ordinary set of three
ammeters, one voltmeter, and one rotary switch, offering
in addition the benefits of serial communication or alarm
management.
• Energy analyzers for both DIN-rail and panel mounting,
also supplied as a kit with three split-core current sensors
or dual 3-phase current transformers.
• Energy meters for DC measurements, which nowadays
are meeting more and more application requirements.

Power transducer for monitoring system
Since the cost pressure on products is higher than ever, the
energy consumption measured by production type allows
for allocating and controlling the costs in a proper and more
accurate manner.
Carlo Gavazzi’s power transducer family, together with
PowerSoft or in combination with the system managing the
facility (e.g. a BMS, a SCADA, a DCS), is able to supply all
the necessary information for a correct and effective energy
cost allocation program.
Installed in the on-board panel or in the switch gears supplying the various machinery, the transducers are able to
measure and transmit via serial communication all the energy consumptions and the most important electrical parameters. The latter can also be used to check the plant
efficiency, plan periodic maintenance or indicate the need
for immediate staff intervention in case of any alarm.

Analysis of power quality and control of electrical parameters
The problems which must frequently occur in electrical systems with inverters and power converters, switching power
supplies for computer and communication systems applications are the following:
• failures on compensation capacitors;
• blowing of capacitor fuses;
• overheating of power supply transformers with a load current below the rated value;
• overheating of motors and frequent failures;
• high neutral conductor currents;
• problems on electronic motor controls.
These are mainly due to the harmonic content of currents
and voltages.
26
The best solution is PQT H, which allows continuous monitoring of the harmonic contents (up to the 63rd harmonics)
of currents and voltages, together with all other electrical
parameters.
The control of up to 16 different electrical parameters by
means of alarm set-points with a specific logic (OR/AND)
and automatic recording of up to 10,000 events (alarm, min,
max, digital input status, reset) allows the operator to monitor any anomaly of the installation and of the loads in real
time, so as to promptly decide and plan any maintenance
action, thus avoiding possible damage to the loads and/or
expensive stopping of the machinery.

Energy metering in Field bus system
Creating the most efficient use of energy is one of the main
factors in developing any successful energy saving program. At time, fan extractors lights and heating systems remain on even when a room or building is unoccupied. Nowadays, in new construction, it is absolutely necessary to have
a building management system (BMS) that provides more
comfort to the tenants/workers, but also uses energy in a
wise and waste free manner. This efficiency can be tested
and regularly controlled by means of the energy meters,
possibly connected to the BMS as a unique system. Carlo
Gavazzi’s solution is Dupline, a field- and installation-bus
that offers unique solutions for a wide range of applications
in building automation, water distribution, energy management, railway systems and many other areas. The system
is capable of transmitting multiple digital and analog signals
over several km, via an ordinary 2-wire cable.
Meters and Dupline join and integrate
A range of energy meters and power analyzers are able to
communicate directly through the Dupline bus, simply by
connecting the relevant twisted pair and getting all the required info. The combination of energy meters and Dupline
is also an ideal solution in very noisy industrial plants, because of the robustness of the Dupline bus when compared
with the traditional serial communication buses.
Main advantages:
• Free topology for a fast, flexible and easy to build step-bystep installation; the system can easily be adapted to new
or unexpected requirements.
• User friendly: easy to code addresses and function, easily
accessible data from a PC/PLC.

• High electrical noise immunity; no shielded cables are
needed, therefore existing cable/conduit/pipe can be utilised.
• Data communication up to 10 km; no signal repeaters are
needed.
• Integration of the metering system with the Dupline doorlight-intrusion-remote controls and load switching.
• Cost-effective solution when compared with ordinary systems.

PowerSoft is an analysis platform suitable for Win 98, 98SE, XP, Vista and Win 7, which has been specifically developed
to interface, by means of the Modbus protocol (RTU and TCP/IP), with the Carlo Gavazzi products for Energy Management. Consisting of a main core and of a series of optional plug-in modules, it allows correct and efficient management
of an electrical distribution system, mainly considering cost reduction. This aim is achieved monitoring the consumptions,
checking the demanded power peaks and adopting accurate analysis and data processing tools.
Interactive synoptics

and check or switch the digital output for test purposes or to
remotely act on an external device. Also available is a table,

display of the harmonic spectrum (up to the 63rd harmonics) in two different modes: the average spectrum of the
10 cycles and the relevant dispersion graph (overlapping
of the 10 spectra of each single cycle). The trigger can be
manually or automatically generated. The manual trigger
can be either single shot or continuous (10-cycle data available every second), while the automatic one is generated
by an alarm condition detected by the instrument. In this
way it is possible to carry out a detailed analysis of what
happened in the monitored system just before the event
that caused the alarm. Each set of 10-cycle data is stored
as a file in the PowerSoft folder and can be recalled and
analysed at any time.

Cost estimation
The software provides a means to estimate the costs, relevant to a selected period based on the energy, water and
gas consumption. This is useful for cost allocation between
the monitored lines, to display the daily trend of the consumption or to identify the reasons for any penalty.
The above features are structured to manage a complex
multitariff contract. The different tariffs during the day and
the distribution of the typical-days in the year can be set according to the supplier tariff regulations in a very easy and
extremely flexible way. Up to 12 tariffs, 24 tariff changes per
day and 365 different typical-days per year can be simply
configured.
Alarms and events
An active alarms window (which automatically pops up
in any case of alarm) advises the user if a setpoint has
been exceeded or if a communication error is present; it
allows the authorised users to acknowledge the selected
alarm. A database allows the list of the events (login, logout, startup, alarm acknowledgment, etc.) to be accessed
and of the alarms (setpoints, communication errors, missing data storage, etc.) and filter-based searches to be carried out. The setpoint alarms can be associated to both an
up and a down threshold on all the variables measured by
all the instruments of the network. The alarm can be software, displayed in the Active alarms windows and stored
in the Alarms and events log, or hardware-based, stored
as above and switching the digital output of the instrument
which is pointing out the anomaly. This powerful tool allows
the operator to monitor any anomaly of the installation and
of the loads in real time, so as to promptly decide and plan
any maintenance actions, thus avoiding possible damage
to the loads and/or expensive stopping of the machinery.

Powersoft, the Energy Management Software
Statistical analysis
PowerSoft carries out statistical analysis on the power
trends and energy consumption by extrapolating the demand of each day of the week, the week-based consumption trends and the estimation of the ideal installed power
for each tariff, calculated with a selectable confidence level.
All this information is aimed to build-up an optimised load
profile, to provide the data to negotiate a better contract. To
improve the reliability of the analysis, any data with abnormal consumption due to external events can be filtered and
removed, as well as the weekends and the holidays.
Internet connectivity
PowerSoft can manage an automatic e-mailing module, capable of notifying the electrical system’s status to one or
more e-mail addresses. The e-mailing can be carried out
on a regular basis and/or as a consequence of a defined
alarm or event. In cost-sharing applications, the energy/utility bill of each final user can be sent to his e-mail box, while
the administrator can receive the consumption summary of
all the users. The web-server module provides a means to
remotely access PowerSoft, using a standard browser without additional licenses, in order to access all the realtime
information and historical data from any location.

Configuration Software
CptBSoft, CptASoft, Wm14ASoft,
Em21Soft, Em2426Soft, Wm5Soft,
PqtHSoft, WM3040Soft.
These user-friendly specific instrument software provides guidance to
set-up the relevant power analyzers
or transducers in a quick and reliable
way. All the available parameters can
be saved into a specific configuration
file, so as to be easily downloadable
from the PC to the instrument/transducer or to be up-loadable from the
instrument/transducer to the PC. Such
a procedure is a cost effective solution, which can also be used to build
up an instrument set-up archive where
each single file, if needed, can be sent
as an e-mail attachment to whoever
is in the field for installation or maintenance purposes, making the job
easier and faster.
CptBSoft and CptASoft
have been developed to program the
parameters and read in real-time mode
the variables of the compact power
transducer (Basic and Advanced version respectively). The CPT transducers are equipped with an auxiliary serial port (RJ12 connection) in order to
easily configure all the models.
WM3040Soft
helps the user to configure all the
numerous parameters of WM30 and
WM40. In the latter case it can be effectively used by mean of the optical
port and allow the data logger download.
Wm14ASoft, Em21Soft and Em2426Soft,
connected via RS485 to a WM14 Advanced, an EM24-DIN, an EM21-72D,
or an EM26-96, allow the instruments
to be fully configured and the realtime
data acquired by all the meters of the
connected network to be read.

WM3, WM5. Controlling the harmonic distortion.
The total harmonic distortion (THD) is the deviation from the reference sine
wave at normal frequency. It is one of the most important factor to define a
good or poor power quality. These analyzers, as well as WM14 Advanced,
WM30, WM40 and EM26 are able to measure, display and control the THD.
