BACKGROUND
Messung Electrical Engineering is the authorised
distributor for Janitza electronics GmbH, world
leader in energy management solutions. Janitza
is leading supplier of cutting-edge digital
energy meters, universal measurement devices,
power quality analysers, peak demand management
systems, etc. Amidst growing concerns regarding
energy consumption and power quality, and with
upcoming legislation from Indian government,
Indian industries have to implement energy
management systems of high international
standards. For efficient power quality
monitoring, power measurement and analysing,
Messung presents Janitza's UMG 512 PRO - a fixed
Class A power quality analyser in compliance with
IEC 61000-4-30 Class A and IEEE 519-2014
standards. But first, lets understand power
quality and its relevant international standards.

ABOUT POWER QUALITY
Power quality refers to a set of electrical
boundaries defined by various documented rules
designed to allow electrical equipment to
function in its intended manner without
significant loss of performance or life
expectancy. This includes the steady and
stable supply of electricity delivered by the
grid. In order to achieve this aim, it is
necessary to constantly and vigilantly monitor
the power conditions within an electrical
network. There are a large number of power
quality parameters, but many of these have not
been well defined. This is where the IEC
61000-4-30 comes in.
5
ABOUT IEC 61000-4-30
An IEC power quality measurement standard that
defines the correct measuring algorithms for
power quality instruments. Defines methods for
measurement and interpretation of power quality
parameters in 50/60 Hz AC power supply systems.
Ensures that different PQ instruments use the
same definitions, and measurement techniques for
various power quality parameters sags/dips,
swells, frequency, harmonics, flicker, etc. By
standardizing the measurement methodologies, IEC
61000-4-30 creates the ability to obtain
reliable, repeatable and comparable results using
any compliant meter.

PARAMETERS DEFINED IN THE IEC 61000-4-30 STANDARD
CLASSES OF IEC 61000-4-30
The IEC 61000-4-30 standard defines the
measurement method, accuracy and time aggregation
to verity of power quality parameters in 3
performance classes to obtain repeatable and
comparable results. 1. Class A - must comply to
the highest performances and accuracy level to
obtain repeatable and comparable results 2. Class
S - accuracy levels are less stringent. Class S
Power quality analysers can be used for
statistical surveys and contractual application
where comparable measurement is not
required 3. Class B - Class B performance is
defined to avoid making any existing instrument
designs obsolete

WHY IS CLASS A SO IMPORTANT?
Due to legal reasons, Class A is almost
mandatory for power utilities IEC 61000-4-30
defines the correct measuring algorithms for
power quality monitoring instruments Instruments
that meet Class A performance, when connected to
the same signals, will produce the same
results Class A instruments must meet the
highest performance and accuracy requirements in
the standard This standard ensures that
different PQM instruments use the same
definitions, and measurement techniques, for
various power quality parameters sags/dips,
swells, frequency, harmonics, flicker, etc.

ABOUT IEEE 519-2014
Establishes levels of voltage and current
harmonic distortion acceptable to the
distribution system based on the input
transformer characteristic and the loads on a
customers facility. Establishes goals for
designing electrical systems that contain both
linear and non-linear loads. The existed
voltage and current waveforms in every part of
the system are explained, and the waveform
distortion goals for the system designer are
established. Many electrical consultants are
including compliance with IEEE 519-2014 in their
design specifications to help reduce harmonic
problems and avoid penalties. The standard is
periodically updated as the industry evolves. The
latest edition is IEEE 519-2014.

UMG 512 PRO
The Janitza UMG 512-PRO is particularly well
suited to the monitoring of power quality in
accordance with current standards, e.g. EN 50160,
IEEE519 or EN 61000-2-4. MAIN FEATURES Class A
Certified to the IEC 61000-4-30 standard, it
provides detailed specifications that a mains
analyser must meet so that the results can also
be consulted in case of disputes. Defines the
necessary parameters, suitable measurement
methods, accuracy and bandwidths. This makes
it possible to easily reproduce and compare
results. Power quality Reliable operation of
modern plants and systems always demands a high
degree of supply reliability and good power
quality. UMG 512 PRO reliably records,
analyses and documents all interferences such as
harmonics, unbalance, transients, voltage dips,
voltage swells, flickers, phase shifts and
reactive power.

UMG 512 PRO
Residual Current Monitoring (RCM) Detects
leakage currents in their initial stages before
they cause system failures or even fires.
Continuous RCM increases the system safety and
availability significantly. Measuring devices
homepage The web server provides a wide range
of data in a user-friendly format. No need to
install any software on your PC a conventional
web browser is all that is required. APPs also
are available for an extended range of
functions. Ethernet-Modbus-Gateway The
gateway can be used to easily include the Modbus
RTU devices that are connected to the master
device as slaves in an Ethernet architecture.
Also possible via a Modbus RTU interface for
devices with identical file formats and matching
function codes. BACnet As soon as a UMG
measuring device has received its BACnet ID and
is integrated into the network, the system
recognises it and displays it in the browser.
This makes configuration very easy.

CONCLUSION
Power quality and supply reliability are
extremely important. High sensitivity devices
and processes are heavily dependent on a clearly
defined power quality. To ensure stable
processes and adequate power supply despite the
increasing number of devices which generate grid
distortions, steps must be taken to improve the
power quality. In India, it is becoming
mandatory by law for industries, infrastructure
projects, data centres, etc. to install power
quality meters and analysers as per the latest
IEEE 519-2014 and IEC 61000-4-30
standards. Janitza offers a comprehensive range
to improve the power quality. Janitzas
