4.9 Energy loss calculator
4.9.1 Functional Description
In this mode, you can estimate the loss of active power and associated costs due to poor power sup-
ply quality. The loss analysis screen is shown in Fig. 4.28. Analysis can be performed in terms of the
desired time.

Parameters to analyse
power loss due to wire resistance (as-
suming the absence of higher harmonics,
unbalance and reactive power)
cost related to P
opt
losses
losses due to higher harmonics
cost related to P
dis
losses
power losses due to network unbalance
cost related to P
unb
losses
power loss due to the presence of reac-
tive power
cost related to P
rea
losses
cost related to a low power factor (large
share of reactive power)
total losses (the sum of the above)
cost related to P
rea
losses
losses which can be reduced by improv-
ing the quality parameters (e.g. compen-
sation of harmonics, elimination of un-
balance), arising from the relationship:
P
sav
= P
tot
- P
