Basic Features

• Integrated bay controller with versatile protection function from medium to extra-high voltage
• Provides control of switching devices
• Synchrocheck, switchgear interlocking protection, and switch-related protection functions (e.g. circuit-breaker failure protection and automatic reclosing)
• 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 I/O, and PROFINET I/O S2 redundancy)
• Reliable data transmission via PRP and HSR redundancy protocols
• Extensive cybersecurity functionality (e.g. as role-based access control (RBAC), protocolling security-related events, signed firmware or authenticated network access IEEE 802.1X)
• Provides simple, quick and secure access to the device data via a standard Web browser to display all information, diagnostic data, vector diagrams, single-line diagrams, and device display pages
• Arc protection
• Optional overcurrent protection with 3-pole tripping
• Also used in switchgear with breaker-and-a-half configuration
• Overcurrent protection also configurable as emergency function
• Captures operational measured variables and protection function measured values for evaluation of the plant state to support commissioning and analyze faults
• Phasor Measurement Unit (PMU) for synchrophasor measured values and IEEE C37.118 protocol integrated
• Enables powerful fault recording (buffer for a max. record time of 80 sec. at 8 kHz or 320 sec. at 2 kHz)
• Point-on-Wave Switching (PoW)
• Flexible adjustment of I/O quantity structure within the scope of the SIPROTEC 5 modular system
