The nominal Line to Line Voltage for the system. This is used
by the meter to calculate the theoretical maximum system power, and
as the reference voltage for setting the Phase Loss threshold.
Maximum is 32000 Volts. For system type 1+N (10), this is a Line to
Neutral Voltage, indicated by
“V LN”. Note: the meter will reject settings

–
The theoretical Maximum System Power is calculated by the
meter from the System Voltage, CT size, and System Type. Power
Factor is assumed to be unity. The value of System Power is used to
determine which combinations of pulse weight and duration are valid
and will keep up with the maximum power the meter will see. This value
