  3. 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 systemsof 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 analyserin compliance with IEC 61000-4-30 Class A and IEEE 519-2014 standards. • But first, let’s understand power quality and its relevant international standards. www.messungelectricalengineering.com

  4. 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. www.messungelectricalengineering.com

  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 qualityparameters: sags/dips, swells, frequency, harmonics, flicker, etc. • • By standardizing the measurement methodologies, IEC 61000-4-30creates the ability to obtain reliable, repeatable and comparable results using any compliant meter. www.messungelectricalengineering.com

  6. PARAMETERS DEFINED IN THE IEC 61000-4-30 STANDARD • CLASSES OF IEC 61000-4-30 • • Power frequency • • Magnitude of supply voltage • • Flicker (by reference to IEC 61000-4-15) • • Supply dips/swells • • Voltage Interruptions • • Voltage unbalance • • Voltage harmonics (by reference to IEC 61000-4-7) • • Voltage Inter-harmonics (by reference to IEC 61000-4-7) • • Mains signaling • • Under- and over-deviation • • Rapid voltage changes • • Flicker class F1 • • Magnitude of the current • • Current unbalance • • Current harmonics (by reference to IEC 61000-4-7) • • Current interharmonics (by reference to IEC 61000-4-7) • • Recording of current along with voltage during events • • 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 analyserscan 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 www.messungelectricalengineering.com

  7. 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.… www.messungelectricalengineering.com

  8. 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 customer’s 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. www.messungelectricalengineering.com

  9. 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. www.messungelectricalengineering.com

  10. 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. www.messungelectricalengineering.com

  11. UMG 512 PRO APPLICATIONS • • Continuous monitoring of the power quality • • Harmonics analysis with power quality problems • • Checking the internal supply network according to EN 61000-4-7, EN 61000-4-15, IEC 61000-4-30 • • Fault analysis in case of problems with the energy supply • • Documentation of the power quality for customers and regulatory authorities • • Ethernet Gateway for subordinate measurement points • • Report generator for power quality standards: EN 50160, IEEE 519, EN61000-2-4, ITIC … • • Report generator for energy consumptions • • Energy Dashboard • • Remote monitoring of critical processes www.messungelectricalengineering.com

  12. 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 metersand analysers as per the latest IEEE 519-2014 and IEC 61000-4-30 standards. • • Janitza offers a comprehensive range to improve the power quality. • • Janitza’s state-of-the-art, cost-effective UMG 512 PRO, backed by Messung’s in-depth knowhow and support, can help customers implement the optimal system • • Trust Messung to help you fulfill mandatory requirements, ensure power quality, maintain supply stability, protect assets and reduce costs. www.messungelectricalengineering.com
