4.1.3 Settings
The devices in the SIPROTEC
®
4 family are delivered with factory default settings. Af-
ter settings are made for specific applications, the devices are suitable for direct use
in power systems.
The windows-based DIGSI
®
4 software program offers an application-oriented inter-
face with thorough guidance for quick and simple setting of the devices.
DIGSI
®
4 is installed on a normal PC. For local use, the PC is connected to the oper-
ating serial interface on the front panel of the device.
4.1.4 Operations
All on-site operations of a SIPROTEC
®
4 device can be done with DIGSI
®
4. Exam-
ples of operations are breaker control, retrieval of information, or changing of setting
groups. All of the operations can also be performed using the HMI on the front of the
SIPROTEC
®
4 device.
4.1.5 Waveform Capture
DIGSI
®
4 can also be used to retrieve waveform data and SER information captured
by the SIPROTEC
®
4 device. The DIGRA
®
4 software program can then be used to
provide several different graphical representations of the captured signals. DIGRA
®
4
also calculates additional values on the basis of the captured signals. The program
presents the data in analogue curves with time base, vector diagrams, circle dia-
grams, and harmonic charts.
Note:
All SIPROTEC
®
4 devices also operate with the proven star coupler (e.g. 7XV5). Thus,
for simple applications, the user can retrieve all information from the office or while on
the road.
