Power-System Data
Overview
The Power-system data are provided with each SIPROTEC 5 device and cannot be deleted. You will find them
in DIGSI under Settings → Power-system data.
Structure of the Power-System Data
The Power-system data contain the block General and the Measuring points of the device. The following
figure shows the structure of the Power-system data:

Figure 6-1 Structure of the Power-System Data
In order to adjust its functions to the application, the device requires some data about the power system. The
necessary settings can be found in the Power-system data under General as well as in the Measuring points.

NOTE
You can find information on the supervision-function parameters in chapter 9.3 Supervision of the Secon-
dary System .
Type and scope of the required measuring points depend on the application. Possible measuring points are:
•
Voltage 3-phase (measuring point V 3-ph)
•
Current 3-phase (measuring point I 3-ph)
•
Voltage 1-phase (measuring point V 1-ph)
•
Current 1-phase (measuring point I 1-ph)
The measuring points have interfaces to the function groups requiring voltage and/or current measured values
of the power system.
Application and Setting Notes – General Settings
Parameter: Phase sequence
•
Recommended setting value
(_:2311:101) Phase sequence
=
ABC
The parameter
Phase sequence
is used to set the phase sequence (
ABC
) or (
ACB
). The setting value applies
to the entire SIPROTEC 5 device.
Use the General function to set the settings in the power-system data.
