Energy Measurements
The P_SE OCR provides various energy readings by integrating the instantaneous power over a network period and storing the totalised energy in several
counters and incremented once every second.
Active and reactive energy counters provide separate and combined values for produced and consumed energy (i.e. energy flowing through the MCCB in
either direction). Absolute counters are unsigned and combine the total energy in either direction regardless of power sign, whereas net counters are signed
and will subtract produced energy from consumed.
The partial energy counters can be reset using one or a combination of the below methods:
-
P_SE OCR embedded display
-
TPED
-
TPCM
Separate non-resetable counters are made available for produced and consumed active energy only. These are separate to the partial energy counters as
they cannot be reset and are permanently retained in OCR memory.

Notice
: Accuracy and correct polarity of all energy related measurements are dependent on several calculation,
power flow and sign convention settings. Refer to the respective sections for details on these settings:
