Properties of SIPROTEC 5
The SIPROTEC 5 devices at the bay level are compact and can be installed directly in medium- and high-voltage
switchgear. They are characterized by seamless integration of fault recorder, protection, and control functions.
General Properties
•
Powerful microprocessor
•
Fully digital measured-value processing and control, from sampling and digitizing of measurands to
closing and tripping decisions for the circuit breaker
•
Complete galvanic and interference-free isolation of the internal processing switches from the system
measuring, control, and supply circuits through instrument transformers, binary input and output
modules, and DC and AC voltage converters
•
Easy operation via an integrated operation and display panel, or via a connected personal computer with
user interface
•
Continuous calculation and presentation of measured values on the front display
•
Storage of min/max measured values and storage of long-term average values
•
Storage of fault indications for system incidents (faults in system) with real-time assignment and instan-
taneous values for fault recording
•
Continuous monitoring of the measurands as well as the device hardware and software
•
Communication with central control and storage devices possible via the device interface
•
Battery-buffered, synchronizable clock
Microcomputer System
All device functions are processed in the microcomputer system.
This includes, for example:
•
Filtering and preparation of the measurands
•
Constant monitoring of the measurands
•
Monitoring of the trigger conditions for the individual functions
•
Querying of limiting values and time-outs
•
Controlling of signals for the logic functions
•
Storage of indications, fault data, and fault values for fault analysis
•
Administration of the operating system and its functions, such as data storage, real-time clock, communi-
cation, interfaces, etc.
•
External distribution of information
Modular Concept
The SIPROTEC 5 modular concept ensures the consistency and integrity of all functionalities across the entire
device series. Significant features here include:
•
Modular system design in hardware, software, and communication
•
The same expansion and communication modules for all devices in the SIPROTEC 5 family
•
Innovative terminal technology with easy assembly and interchangeability and the highest possible
degree of safety
•
The same functions can be configured individually across the entire family of devices
•
Ability to upgrade with innovations possible at all times through libraries
•
Open, scalable architecture for IT integration and new functions
