6.13 Measurement parameters
Setting the power factor and cos sign convention
This parameter is used to configure the sign for power factors and cos according to the IEC
convention or the IEEE convention in the four-quadrants diagram.
IEC convention
IEEE convention
P < 0 P > 0
Q > 0
II Capacitive (lead) I Inductive (lag)
cos < 0 PF > 0
cos > 0
Q < 0
III Inductive (lag) IV Capacitive (lead)
cos < 0 PF > 0
cos > 0
The IEC convention is indicated when the equipment downstream of the circuit breaker may
operate in turn as a receiver and as a generator. It is indicated for countries using the IEC
standards.
The IEEE convention is indicated for all countries using the IEEE standard.

Setting the averaged value over interval parameters
This parameter is used to configure the length of the integration interval and the type of
integration in order to perform the averaged value calculations correctly.
Calculating the averaged values over a specific interval involves integrating the currents and
powers over a time interval (see § 6.7).
N.B.
The parameter "Demand Period" is not taken into account in the average value calculation
if the "Demand Mode" setting (type of integration interval) is Sync. Bus (Synchronised
integration interval).
Demand period Default setting
1 – 60 min. (increments of 1 min.) 30 min
Demand mode Default setting
Fixed – Sliding – Sync. Bus Fixed
