Depending on the equipment variant, the mobile power analyzer is equipped with a UMG 96RM-E or UMG 512. Differential current and voltage quality (harmonics, short-term interruptions, asymmetries, ...) can be measured everywhere.
Areas of application
MRG 512-PRO PQ Flex
The MRG 512-PRO PQ Flex measures harmonics currents up to the 63rd harmonic as well as flicker and short-term interruptions. Applications for the MRG 512-PRO PQ Flex include high-quality network analyses at Class A level (IEC 61000-4-30), validation of device accuracy, and much more. GridVis®-Basic power grid monitoring software is available for download free of charge. Thanks to a three-hour UPS buffer, there are no gaps in measurement in the event of a power failure. The device also has PLC functionality.
MRG 96RM-E RCM Flex
TheMRG 96RM-E RCM Flex measures harmonic currents up to the 40th harmonic current. Possible applications include the analysis of electrical disturbance variables in the event of network problems, high-quality comparative measurements of energy measurement devices and meters, or the recording of residual currents via external current transformers. GridVis®-Basic is also available here free of charge.
Advantages
- Flexible measurement of power quality and residual current
- Inexpensive, robust and compact network analyzers
- Simple operation and quick integration of measuring cases
- High measuring range of 100-4000 A thanks to Rogowski current transformers with measuring range switching
- Acquisition of all power quality parameters (harmonics current, short-term interruptions, asymmetries, ...) – depending on the model
- Remote access via Ethernet and embedded web server
- GridVis®-PQ analysis software
- Standard PQ reports, depending on the version: EN 50160, IEEE519, ITIC, IEC 61000-2-4
- Cost center report
- Large 256 MB internal memory for recording measurement data
- Avoidance of gaps in measurement in the event of a power failure thanks to three-hour UPS buffering (only with MRG 512-PRO PQ Flex)
- Measurement up to the 63rd harmonic (MRG 512-PRO PQ Flex)
Features and functions of the MRG 512-PRO PQ FLEX
Mobile Class A power quality analyzer for monitoring power quality
The mobile MRG 512-PRO PQ Flex power quality analyzer with integrated UMG 512-PRO Class A measurement device can be used in a variety of ways. This device can be used to measure harmonics currents up to the 63rd harmonic and detect short-term interruptions. The device records residual currents, is UPS buffered for up to 3 hours, and has an Ethernet interface for communication via various protocols.
Rogowski current transformer included in the scope of delivery
Flexible Rogowski coils offer a major advantage, particularly for applications with large cable cross-sections. But Rogowski current transformers are also better than iron-core current transformers when it comes to higher frequencies (harmonics current).
Large measurement data storage
The large measurement data storage also allows long-term recordings, such as those required for the one-week power quality analysis in accordance with EN 50160.
