Network Analyzer - ABB SACE Tmax XT2 User Manual

30 - Network Analyzer

The Network Analyzer function allows setting voltage and current checks for a long time, to
Presentation
analyze the system's operation.
For this purpose, voltages and currents are monitored to detect:


Each monitor is associated with control parameters that can be set by the user and to counters
that are incremented each time the control condition settings are reached.
Parameters The counter configuration parameters are available in the Settings - Network Analyzer menu
(page 29).
In the Settings menu it is also possible to set the Measurement interval parameter, which defines
the period of each control session.

Counter control threshold Under V Th
The value is expressed as a percentage of the rated voltage Un,
which can be set in a range of: 75% .. 95% Un, with 5% steps
Counter control threshold Over V Th
The value is expressed as a percentage of the rated voltage Un,
which can be set in a range between: 105, 110, 115% Un
Counter control threshold Unbalanced.
The value is expressed as a percentage of the rated voltage Un,
which can be set in a range of: 2% .. 10% Un, with 1% steps
Counter control threshold V interruption.
The value is expressed as a percentage of the rated voltage Un,
which can be set in a range of: 10% .. 95% Un, with 5% steps
