Description
Branch current surge
protection alarm threshold.
When the percentage of the
branch current to the rated
branch current exceeds the
threshold, an alarm is
generated.
The system can display three
types of harmonics based on
the settings.
Specifies whether to enable
harmonic alarms. If this
parameter is set to Enable,
an alarm (voltage/current
harmonic alarm) is
generated when the alarm
condition is met.
When the system frequency
is higher than the rated
frequency plus the value of
this parameter or is lower
than the rated frequency
minus the value of this
parameter, the system
generates an alarm.
If this parameter is set to
Enable, an alarm is
generated when the alarm
condition is met.
If this parameter is set to
Enable, an alarm is
generated when the alarm
condition is met.
If this parameter is set to
