SIPROTEC 4 7SA522 Distance Protection Relay for Transmission ...

SIPROTEC 4 – 7SA522
Distance Protection Relay for Transmission Lines
System SIPROTEC 4/SICAM
SIPROTEC 4 as an integral part
of SICAM energy automation
system
SIPROTEC 4 is tailor-made for use
in the SIMATIC-based SICAM
energy automation system. The
SICAM family consists of the following
components:
− SICAM RTU, the modern telecontrol
system with automation
and programmable logic functions
− SICAM SAS, the modern integration
of switchgear automation
and information technology
− SICAM PCC, the information
and communication technology
on a PC basis

Data management and communication
is one of the strong points
of the SICAM and SIPROTEC 4
system. Powerful engineering
tools (SICAM plus TOOLS based
on STEP7 and SICAM Win CC)
make working with SICAM convenient.
The SIPROTEC 4 units
are optimally matched for use in
SICAM SAS and SICAM PCC.
With SICAM and SIPROTEC 4
continuity exists at three central
points:
− Data management
− Software architecture
− Communication.

access
All central system components
(SICAM and SIPROTEC 4 CPUs,
SICAM WinCC, SICAM plus
TOOLS, bay controllers and protection
equipment), as well as the
DIGSI 4 operating program, are
established on the same basis.
The ability to link SICAM/SIPRO-
TEC and other components of the
substation control, protection and
automation is assured via open
interfaces, such as
IEC 60870-5-103 or PROFIBUS.
Service interface
The service interface can be used
asa2 nd operating interface.
DIGSI 4 offers the additional possibility
of accessing bay controllers
via modem. Thus the full
range of DIGSI 4 functionality is
available at the office desk or
when travelling (by laptop and modem).
This permits rapid and extensive
access for the service personnel.
All settings and control
commands are available and it is
possible to read the operational
and fault event logs, fault records
as well as ope- rational measured
values.

Star coupler
All SIPROTEC units operate also
with the proven star coupler. The
star coupler is used for simple
applications which also give the
user an alternative method of
retrieving information remotely.
