Phase Loss Voltage Threshold in percent of system voltage (register
134). Default is 10 (%). Any phase (as configured in register 130)
that drops below this threshold triggers a Phase Loss alert - i.e.
if the System voltage is set to 480 V L-L, the L-N voltage for each
% 1-99 phase should be 277 V. When the threshold is set to 10%, if any
phase drops more than 10% below 277 V, (less than 249 V), or
if any L-L voltage drops more than 10% below 480 V (less than
432 V) the corresponding phase loss alarm bit in register 146 will
be true.
Phase Loss Imbalance Threshold in Percent. Default is 25% phase
to phase difference. For a 3-phase Y (3 + N) system type (40 in
register 130), both Line to Neutral and Line to Line voltages are
% 1-99 tested. In a 3-phase Δ System type (31 in register 130), only Line
to Line voltages are examined. In a single split-phase (2 + N)
system type (12 in register 130), just the line to neutral voltage
are compared.

Description
Scale Factors
Note: These registers contain a signed
integer, which scales the corresponding
integer registers. Floating point registers
are not scaled. Scaling is recalculated
when the meter configuration is changed.
Phase Loss Output
Note: The phases tested are determined by
the System Type.
kWh Pulse Contacts
Note: The kWh pulse contact can keep up with a maximum power (Watts) of
1800000 x Wh pulse weight ÷ contact closure duration (in msec)
