THE GAME CHANGER IN POWER QUALITY ANALYSIS: UMG 512-PRO

Posted by messungelectricalengineering on February 4th, 2022

Power qualityis defined as the power grid\'s ability to supply a clean and stable flow of power. The power flow should have a pure sinusoidal wave form and should remain within specified voltage and frequency tolerances.

However, no real-life power source is so perfect. Deviations are frequent due to increasing non-linear and other loads disturbing the grid. Grid operators are challenged by the process becoming more complex with new players and technologies.

WHY DO WE NEED GOOD POWER QUALITY?

Simply put, lower power quality results in higher energy costs, not to mention the toll it takes on any machine or equipment.

Insufficient power quality can inflict serious losses on business and economy. Good power quality saves money and energy. Direct savings come from lower energy costs and reactive power tariffs. Indirect savings accrue from minimising circumstances such as damage and premature aging of equipment, breakdowns that cause loss of production or loss of data/work.

In some instances, it may even pose a hazard to human life and property. Poor power quality can cause a dangerous overload in the circuit which can result in overheating and fires - a fact often overlooked by managements.

The growing use of highly energy-dependent, sensitive electronic equipment in commercial and industrial settings makes it imperative to ensure power quality for maintaining a device\'s optimal performance.

WHY INVEST IN A POWER QUALITY ANALYSER (PQA)?

Power quality analysers are electronic devices used to continuously monitor and analyse electricity lines for disturbance which can disrupt the reliable delivery of energy or cause damage to equipment plugged into the grid. Power quality disturbances include events such as voltage sags and swells, transients, harmonic distortion and voltage/current imbalance.

A PQA works by strategically sampling the AC voltage at various points along a waveform shape. From there, it digitizes all points or values and utilizes a microprocessor in order to execute a numerical analysis (which arrives at harmonic frequency magnitudes).

Being able to monitor current, a PQA can systematically calculate and display common power values, what gives you a whole picture of how your system works and where it fails.

THE GAME CHANGER: JANITZA\'S UMG 512-PRO

For the bestpower quality monitoring, power measurementand analysing, check out Janitza\'s UMG 512-PRO - a fixedClass A power quality analyserin compliance with IEC 61000-4-30 Class A and IEEE 519-2014 standards.

The Janitza UMG 512-PRO is particularly well suited to the monitoring of power qualityin accordance with current standards, e.g. EN 50160, IEEE 519 or EN 61000-2-4.

Main features

Class A: Certified to the IEC 61000-4-30standard, it provides detailed specifications that a mains analyser must meet so that the results can also be consulted in case of disputes. The standard 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.

Residual Current Monitoring (RCM): Powerful RCM residual current monitoringalready detects leakage currents in their initial stages before they cause system failures or even fires. Continuous RCM monitoring increases the system safety and availability significantly.

Measuring devices homepage: The web server for the measuring device provides a wide range of data in a user-friendly format. The user does not have to install any software on their PC; a conventional web browser is all that is required. In addition to the modern homepage, APPs are available for an extended range of functions.

Ethernet-Modbus-Gateway: The Ethernet Modbus gateway can be used to easily include the Modbus RTU devices that are connected to the master device as slaves in an Ethernet architecture. This is 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.

GridVis® – network visualisation software: With GridVis®, Janitza offers powerful, user-friendly energy supervision softwarefor the development of energy and power quality monitoring systems. The basic version GridVis®-Basic, which is part of the scope of delivery of the measurement devices, serves both for the programming and configuration of the UMG 512-PRO

and also for the reading out, saving, display, processing and analysis of the measurement data.

CONCLUSION

For reliable power quality monitoring, error detection and extensive analyses for detailed insights, Janitza’s UMG 512-PRO Class A power quality analysercan help enterprises improve power quality, maximise plant availability, save energy costs and avoid penalties.
