The comprehensive Janitza product range stands for Energy management, power quality monitoring and residual current monitoring (RCM)in a single system environment energy management.
For system assurance and highly-availability power supply, continuous monitoring of the power quality in all technical systems per IEC 61000-2-4 is essential. This helps to avoid unnecessary repair costs and production downtimes.
For continuous power quality management, Janitza offers a range of power quality meters that enable power quality monitoring as per established standards such as EN 50160, IEEE 519 or EN 61000-2-4.
WHAT ARE POWER QUALITY METERS?
Power quality meters are smart devices that can gather, analyse and interpret raw measurement data into useful information. They have the ability to communicate with other intelligent devices.
Features include:
Measurement of power quality disturbances such as Harmonics, Sag-Swell, Transients, Unbalance, etc.
Measurement of consumed/delivered energy (4 Quadrant meter)
Inbuilt storage memory to collect and analyse historical data.
Documenting and trending system performance to increase system reliability
WHAT IS CLASS A TYPE POWER QUALITY ANALYZER?
Class A is defined by the IEC 61000-4-30 standard which provides detailed specifications that a mains analyzer must meet when precise measurements are necessary such as in case of disputes with electricity supply companies.
The standard defines the necessary parameters, suitable measurement methods, accuracy and bandwidths. This makes it possible to easily reproduce results, and compare data of two meters.
As per IEC 61000-4-30, the basic measurement time interval for parameter magnitudes (supply voltage, harmonics, interharmonics and unbalance) shall be a 10-cycle time interval for a 50 Hz power system or a 12-cycle time interval for a 60 Hz power system.
JANITZA UMG PRO SERIES
Besides UMG 512-PRO, the fixed Class A power quality analyzer, Janitza offers other meters in their UMG PRO Series. They include:
UMG 509-PRO
Powerful network analyzer with colour graphic display and high degree of user friendliness. Also, PLC functionality (Jasic), integrated residual current monitoring and comprehensive range of protocols for simple incorporation into existing communication architectures. UMG 509-PRO measures with an accuracy of 0.2 %.
UMG 604-PRO
Power analyzer for DIN rail mounting with latest communication capabilities (Ethernet, PROFIBUS, Jasic (PLC functionality) and integrated homepage). Comprehensive power quality measurements can be undertaken.
UMG 605-PRO
Power quality analyzer for DIN rail mounting with standard-compliant power quality measurement per IEC 61000-2-4 and EN 50160. Measurement process implemented in accordance with DIN EN 61000-4-30.
FEATURES OF JANITZA UMG PRO SERIES
Janitza’s new UMG PRO series combines the latest technology with excellent functions and attractive design. The increased variety of functions and comprehensive illustration options enable measurement data and measurement results to be analysed and interpreted more easily.
Data can be processed, visualised and analysed with the help of the pre-installed Janitza APPs. APPs are a function extension of the device homepage. The traffic-light principle makes complex power quality analyses, for example, understandable for everyone.
JANITZA VISUALISATION SOFTWARE AND APPS
With GridVis®, Janitza offers powerful, user-friendly software for 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 PRO series of devices, and also for the reading out, saving, display, processing and analysis of the measurement data.
Janitza APPs can be called up via the measurement device homepage for web-based data display and configuration. No software installation is required. The Apps include:
Mini EnMs APP
EN50160 Watchdog APP
IEC 61000-2-4 Watchdog APP
Multitouch APP
Push Service APP
How Mini EnMs APP works
Mini EnMs App makes it possible to view real time and historic measurement value data of master and slave meters in graphs right from your energy meter.
The master device collects the data from the connected slave devices and displays them on its own homepage.
The app has been designed for small applications without a GridVis-use!
Can connect and record data from up to 16 slave devices.
