- The mobile measuring case MMD 97 records all voltage quality parameters and logs this data as a single-phase or three-phase measurement in the low-voltage network (230 / 400V AC) in distribution networks in transformer stations, switchgear and as direct consumption measurement on machines and buildings. The heart of the system is a built-in UMD 97EL in an IP65 plastic housing.
- With the firmware modules PQ S and GQ the device maps all functions of the voltage quality according to EN 50160.
- The measuring box is equipped with voltage inputs 333mV AC, which enables a direct connection of flexible Rogowski coils as well as cable conversion transformers the execution KBR allows.
