System losses (
E
) are a fixed percentage, mutually agreed upon between two electric
utilities, about an interchange point that lies on a branched line. As such,
E
is not a
physical property of any particular line, transformer or the meter, so no further
guidance on how best to calculate the coefficient
E
can be provided here. All
instructions following will be concerned only with the calculation of the coefficients
A,
B, C,
and
D
. Users who do not intend to use system losses should simply set
E
equal
to zero.
A detailed application note on loss compensation in the PPX II can be found in the
documentation library of the Novatech website,

5.8 Energy
Separate values are maintained for both positive and negative Watt-hours, positive
and negative VAR-hours, and VA-hours, for each feeder. These energy quantities are
calculated every cycle from the Total Watts, Total VARs, and Total VAs, and the
values are stored into non-volatile memory every 15 seconds. Energy values may be
