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 comprehensive integration of 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 circuits from the system
measuring, control, and supply circuits through instrument transformers, binary input and output
modules, and DC and AC voltage converters
•
Easy operation using an integrated operator and display panel, or using a connected personal computer
with user interface
•
Continuous display of measured and metered values at the front
•
Storage of min/max measured values (slave pointer function) 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
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
•
Functional integration of various applications, such as protection, control, and fault recorder
•
The same expansion and communication modules for all devices in the 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
•
Multi-layered security mechanisms in all links of the security chain
•
Self-monitoring routines for reliable localization and indication of device faults
•
Automatic logging of access attempts and safety-critical operations on the devices and systems
Redundant Communication
SIPROTEC 5 devices maintain complete communication redundancy:
•
Multiple redundant communication interfaces
•
Redundant and independent protocols to control centers possible (such as IEC 60870-5-103 and
IEC 61850, either single or redundant)
•
Redundant time synchronization (such as IRIG-B, SNTP, or IEEE 1588)
