MR 8050 -
Schuetz Messtechnik GmbH
With the MR 8050 resistances highly inductive Resistance Meters windings of transformers, motors and reactors can be measured. (range 100 µΩ with 0.01µΩ resolution up to 6 kΩ). The performance of the test objects can be up to 800 MVA or even more. The magnetic loading of a transformer is performed quickly using a high loading voltage (60V). This is important for time critical measurements (cooling curves). The unloading of the transformers core is very fast, very safe, as the energy is total destroyed in the MR 8050.
