Click this button to print the selected measurement period using the default settings, or
with the desired start time and period setting.
Click S, to view details such as the interval information, including number of intervals,
voltage (V) and current (I) overflow, as well as power supply failure (N). (G) signifies a
valid measurement interval. (C), a clamp error, signifies the type of the current sensor
changed during a measurement.
Values that are out of the measurement range are marked with the symbol
'>' on the left side of the numeric value.
Correlations of Voltages and Currents
The voltage and current values can be used to get information about sources of
disturbances in the power network. The relation between the extreme voltage values
(V , V ) and the actual phase currents can be seen. On the other hand, the voltage at

Events

The UNIPEDE DISDIP table is used for the classification of voltage dips. The events are
sorted by their duration and deviation from the nominal value, and their quantities are
listed in the corresponding fields. An extended UNIPEDE DISDIP table can be found in
the corresponding analysis in PQ Log. In addition, voltage interruptions and surges are
also displayed. The part of DISDIP table defined by UNIPEDE is marked with a frame.
