E50417-H1076-C420-A2, Release 12.01.2015
Save:
Enter the name of the new limit values or
overwrite an existing set of values.
Save as...:
Saves the limit values currently in effect
under a new name.
Open:
Select a limit value data set and close by
clicking OK.
Note
If the limit values specified are incorrect, the results of your evaluation will also be wrong. This is
especially true for lists of events, such as dips and interruptions.
The limit values are saved to the database.
5.1.5.4
Network quality report
This item is for the purpose of composing and printing out a measurement protocol reflecting all parameters required
by the standard EN 50160. At the same time, there is an automatic analysis of the measurement results based on the
limit values specified. If the option
is selected, the system takes account of the fact that in
cases of voltage dips, overload, or outages, it is possible for invalid network frequency values, voltage fluctuations,
flicker, asymmetry, voltage overload and THD to occur, and it prevents the event from being counted repeatedly in
various quantities (in accordance with the standard IEC 61000-4-30’s flagging technique).
In the protocol's header, the data for measurement are applied from the program item Setup. Next is a total overview
of the measurement results in order to display at a glance where thresholds were violated.
The report can be printed out and saved.
Structure of the results tables:
Unit
of the following quantities
Portion
of the measurement values taken into account for calculations. Usually 95 % or 100 %.
limit values,
on which the evaluation is based
Conductor (line)
under investigation if there is no evaluation of the overall system
Min/Max value
– the extreme signal values which occur during measurement
Values out of bounds
are values which exceed the specified limits
