PQ Plus MMD 97 Network diagnostics 3-phase, 1-phase Data logger

Overview

4 quadrant measurement;LED illuminated display;Integrated OS measurement up to 50th harmonic U/I;4 operating keys

Description

The MMD 97 mobile measuring case records all voltage quality parameters and logs these data as single-phase or three-phase measurements in the low-voltage network (230/400V AC) in distribution networks, transformer stations, switchgear and as direct consumption measurement on machines and in buildings. The core is a built-in UMD 97EL in an IP65 plastic housing. With the firmware modules PQ S and GO, the device maps all voltage quality functions according to EN 50160. Application: The MMD 97 measuring case is used for measuring mains quality and consumption in NSHVs and sub-distributions. It performs network analysis up to the 50th harmonic order for I/U and is suitable as a reference measuring point for ISO 50001 checks. The MMD 97 measuring case is equipped with 333mV AC voltage inputs. This enables the direct connection of flexible Rogowski coils type MMD FLEX SET. Ø 115mm.
