same applies to the power factor cos
. It is occasionally desired to define the power drawn from the line (e.g.
as seen from the consumer) positively. Using parameter

the signs for these components can be
inverted.
The calculation of the operational measured values also takes place while a fault is running. The values are
updated at intervals of > 0.3 s and < 1 s.
2.3.3.2
Transmitting Measured Values
The main propose of the measured values in the MU is to support the commissioning. Measured values can
alsobe transmitted to a central control and storage device via port F.
The measuring range in which these values are transmitted depends on the protocol and additional settings, if
applicable.

Information List
Protocol
Transmittable measuring range, format
IEC 61850
The primary operational measured values are transmitted.
The measured values as well as their unit format are set out in detail in the PIXIT docu-
ment of the 7SC805 device.
The measured values are transmitted in „Float“ format. The transmittable measuring
range is not limited and corresponds to that of the operational measurement.
