1) Up to this line, the measurement values are within the tolerance range.
2) Display of the values from the standard EN 50160.
3) Values lie far beyond accepted tolerances.
Evaluation: By default, the analysis is carried out for the entire measurement, and other time spans are available as
alternative selections.
On the basis of a particular measurement, the analysis can be carried out over different timeframes and with different
limits.
Standard: Since different limit data sets besides EN 50160 can be defined, it's possible to evaluate a measurement
according to a variety of requirements and to save the results for subsequent comparisons.
Case 1 - Measurement L-N (4 wire system), no converter
The device is able to measure up to 1000 V
Case 2 - Measurement L-L (3 wire-system) with converter in a 20 KV
operating voltage
converter: 20kV primary voltage, 100 V secondary voltage
