MRG 508/511 – Portable Network Analyzer for Network Data-Logging

Network analysers from the MRG range are intended for fault analysis and cause identification in low voltage systems. Thus, with overloaded capacitors in a reactive power compensation system a long-term harmonics analysis can provide information on whether the overload is perhaps caused by too much noise on the grid (THD-U), for example. However, the recording of load profiles can also play an important role in the new dimensioning of system components or for the negotiation of power supply contracts. Mobile network analysers offer an advantage in particular with sporadic problems or fault analysis or in cases where certain measured values must be even more closely localised. Along with the large number of electrical measured values this range offers a multitude of additional functions such as the saving of minimum and maximum values, operating hours counter, bi-metallic strip function, password protection and much more.

The MRG range is used as a portable measuring device in distribution systems where there are no fixed integrated measurement devices available. These are ideally suited to carrying out mobile measurements, e.g. for the design of reactive power compensation systems, for the determination of load profiles or harmonic analyses of up to 40th (MRG 508) or 63rd (MRG 511) level harmonics. Thanks to the integrated measured value memory it is not necessary to set up additional equipment, such as a laptop or printer, with the measurement device. The evaluation can be carried out conveniently “back at base” on the PC.
