Functions :
DIGSI 5 permits all functions to be configured and combined as required.
- Integrated bay controller with versatile protection function from medium to extra-high voltage
- Control of switching devices
- Synchrocheck and switchgear interlocking protection
- Integrated electrical Ethernet RJ45 for DIGSI 5 and IEC 61850 (reporting and GOOSE)
- Up to 4 pluggable communication modules, usable for different and redundant protocols (IEC 61850-8-1, IEC 61850-9-2 Client, IEC 60870-5-103, IEC 60870-5-104, Modbus TCP, DNP3 serial and TCP, PROFINET IO, PROFINET IO S2 redundancy)
- Virtuelle Netzwerkaufteilung (IEEE 802.1Q – VLAN)
- Redundancy protocols PRP and HSR
- Arc protection
- Extensive cybersecurity functionality, such as role-based access control (RBAC), protocolling security-related events, signed firmware or authenticated network access IEEE 802.1X
- Simple, quick and secure access to the device data via a standard Web browser to display all information and diagnostic data, as well as vector diagrams, single-line and device display pages
- Graphical logic editor to create powerful automation functions in the device
- Optional overcurrent protection for all voltage levels with 3- pole tripping
- Also used in switchgear with breaker-and-a-half configuration
- Overcurrent protection also configurable as emergency function
- Selective protection of overhead lines and cables with single-ended and multi-ended feeders using protection communication
- Secure serial protection data communication, also over great distances and all available physical media (fiber-optic cable, 2-wire connections and communication Networks)
- PQ-Basic: voltage unbalance; voltage changes: overvoltage, dip, interruption; TDD, THD and Harmonics
- Capturing operational measured variables and protection function measured values to evaluate the plant state, to support commissioning, and to analyze faults
- Phasor Measurment Unit (PMU) for synchrophasor measured values and IEEE C37.118 protocol integrated
- Powerful fault recording (buffer for a max. record time of 80 s at 8 kHz or 320 s at 2 kHz)
- Point-on-Wave Switching (PoW)
- Auxiliary functions for simple tests and commissioning
- Flexibly adjustable I/O quantity structure within the scope of the SIPROTEC 5 modular system
