6 The value is calculated using a simplified technique as a
relation of the maximum deviation of phase values from a 3-
phase average value to a 3-phase average.
7 The value is calculated using a simplified technique as a
one third of the RMS value of a 3-phase vector sum.
8 Not affected by loss compensation – always indicate
readings at the metering point.
NOTE
Designations of some enginering demands and billing energy
and demand registers are shown using a new short name
notation available in PAS V1.4. By default, PAS uses long
names compatible with older versions of PAS. You can select
a desired notation from the Tools/Options/Preferences tab.
PAS does not allow to store data in files using different data
names. If you have a file uploaded with a previous version of
PAS using long data names, either continue using long data
names, or store data in a new file.
See table below for a list of parameters with short and long
names.
