Power Quality Analyzers

Power quality analyzers are used for the continuous measurement and monitoring of the voltage quality according to international standards such as EN50160 and IEC61000-2-4. Part of this is the short-time and long-time flicker. Voltage dips, peaks and transients are also recorded. The Power Quality Analyzers are equipped with sufficient memory, so that measurement values can be stored in the memory for a longer period of time. The analyzers are delivered in a panel installation variant (UMG 512-PRO) and a DIN rail variant (UMG 605-PRO).

Embedded web interface

Janitza's power quality analyzers are equipped with an intuitive web interface for PC, tablet and smartphone. The web interface provides a kWh reporting function, embedded line writer, power quality report generator and an analysis tool for voltage dips and peaks.

Interfacing

All analyzers have 2 digital inputs and outputs, a temperature measurement input, an Ethernet port (TCP / IP), Profibus and RS485 port. Through these ports, Janitza supports many protocols such as Modbus, Profibus, Profinet, Bacnet, HTTP, with which the analyzers can easily be connected to the parent systems.

Features Power Quality Analyzers

Area of application

Because the power quality analyzers measure voltage quality according to international standards such as the EN50160, the analyzers are often used as a control meter on the incoming fields (level 1 measurement), generator fields and in public networks.

Features power quality analyzers:

  • 4 quadrant measurements in IT, TN and TT networks
  • 5 voltage and 4 current measurement inputs (3 phases + zero)
  • 2 additional current measurement inputs for differential current measurement
  • Measurement according to IEC61000-4-30 - class A
  • Scan speed: 20kHz
  • Calculation of more than 2000 variables per cycle (200ms)
  • JASIC graphical programming functions
  • Analysis of harmonics, interharmonics and resonances

Embedded Webinterface

Janitza's power quality analyzers are equipped with an embedded web interface that makes it possible to visualize measurement values without the use of additional software. A standard browser is sufficient. The responsive design allows good visualization and operation on a smartphone, tablet and PC.

Web interface functions:

  • Real-time visualization of all imaginable quantities
  • Integrated consumption manager
  • Embedded line writer for current and historical values
  • Analysis tool for voltage dips, peaks and transients
  • Automatic web-based report generator for power quality
  • Remote control of the power quality analyser

Power Quality Analyzer Janitza UMG 512-PRO: insight into consumption, interference and mains voltage quality

Power quality analyzer to prevent problems before they actually arise

With a 5th and 6th current transformer input it is possible to continuously monitor earth fault currents. As a result, a periodic insulation test of your installation is no longer necessary. The Janitza UMG 512-PRO is equipped with a temperature input. Events can also be registered for short-term deviations in frequency and/or reactive power. This makes the analyzer suitable for measuring generators of, for example, emergency power supplies in critical applications.

Power quality analyzer UMG 512-PRO

The Janitza UMG 512-PRO is an all-in-one power quality analyzer and measures the voltage quality according to international standards such as EN 50160, IEEE519 and EN 61000-2-4. Power quality problems are quickly detected, because the quality of voltage and current are automatically reported in accordance with the applicable standards. Voltage dips, peaks and transients that can lead to failure are automatically registered and reported via, for example, e-mail or the web interface. On the integrated website of the power quality analyzer, you immediately see the status of the power quality of your electrical installation. The website is accessible via PC, laptop, tablet and smartphone.

Features of the power quality analyzer UMG 512-PRO:

  • Measuring voltage quality according to IEC61000-4-30, class A
  • Measuring consumption parameters
  • Measuring power quality parameters such as harmonic to the 63rd order
  • Measuring short interruptions, transients and peaks
  • Measuring earth fault currents
