30 - Network Analyzer
Presentation
The Network Analyzer function allows setting voltage and current checks for a long time, to
analyze the system's operation.
For this purpose, voltages and currents are monitored to detect:
Voltage sequences (Over, Under, Pos and neg)
Voltage imbalance (Unbalanced)
Voltage drops, of a short duration (Interruptions) and slow (Sag)
Voltage increases, of a short duration (Spike) and slow (Swell)
Harmonic distortion of voltages and currents (THD)
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
In the
Settings
menu it is also possible to set the
Measurement interval
parameter, which defines
the period of each control session.
NOTE: the parameter is the same used for current measurements and maximum
voltages
