SIPROTEC
™
SIPROTEC has established itself across the
market as the standard for numerical
protective relaying. Besides the common
system platform and the unique type
DIGSI 4 service interface that may be
used for all protective devices, it also
supports the new IEC 61850
communication standard.
IEC 61850 – what it is and what it can
achieve?
Users and manufacturers jointly
developed the new international standard
IEC 61850, which was approved in early
2004. The agreed aim of this standard is
to arrive at a complete communication
solution for substations, thus providing
users with interoperability among
different makes on the basis of Ethernet
technology. This opens up a whole new
dimension in efficient substation
management. Not only short-term
savings in operation and maintenance,
but also simplified engineering, less
complexity and long-term expandability
can make you one of the winners in
tomorrow’s power market.
With type SIPROTEC protective relays and
bay control units from Siemens, we offer
all the advantages of an expert and
innovative partner in the field of
protective relaying and substation
automation. We bring you attractively
priced intelligent solutions by paying
particular attention to lowering your life
cycle and system management costs.
These solutions are the first ones
available on the market with the
international IEC 61850 standard.
To enable you to profit from these
advantages as quickly as possible,
Siemens collaborated in the preparation
of this international standard and made
every effort to ensure no time was lost in
bringing it out. The result is certainly
worth a look, because type SIPROTEC and
other power automation products and
Siemens systems are available on the
basis of the IEC 61850 standard and can
even be retrofitted in systems supplied
since 1998.
System advantages one bay, one unit
The type SIPROTEC 4 protective relay
family offers fully integrated protection,
control, monitoring and automation
functions incorporated in a single device.
For many applications, this product
contains all the functions you need to
meet all your protection and control
requirements with just one unit per
section, saving on investment and
installation costs and enhancing
availability.
Type DIGSI 4 – one tool for all tasks and
products
Type DIGSI 4 is a computer program
designed for all type SIPROTEC protective
relays. Type DIGSI 4 offers users a
universal tool for all support tasks from
setting and commissioning of devices to
simple analysis and documentation of
system faults. Our powerful analysis tool
speeds up troubleshooting and supplies
important service information.
Type SIPROTEC protective relays and
bay controllers - the first devices
available with IEC 61850.
