Description
Mains three-phase current
imbalance alarm threshold.
When the difference between
the highest and lowest mains
three-phase currents is
higher than the alarm
threshold, the system
generates an alarm.
If this parameter is set to
Enable, the system generates
an alarm when the mains
current is below the lower
current threshold. If this
parameter is set to Disable,
the system does not generate
the alarm under any
condition.
If this parameter is set to
Enable, the system generates
an alarm when the mains
current exceeds the higher
current threshold. If this
parameter is set to Disable,
the system does not generate
the alarm under any
condition.
If this parameter is set to
Enable, the system generates
an alarm when the mains
three-phase current is
imbalanced. If this parameter
is set to Disable, the system
does not generate the alarm
under any condition.
If this parameter is set to
Enable, the system generates
an alarm when the branch
current is below the lower
current threshold. If this
parameter is set to Disable,
the system does not generate
the alarm under any
condition.
