Basic Features

• Feeder and overcurrent protection for all voltage levels
• Directional and non-directional overcurrent protection with additional functions
• Optimized tripping times due to directional comparison and protection data communication
• Detects intermittent ground faults and automatically block static measuring functions to avoid the flooding of messages and fault records
• Uses pulse detection method to detect transient ground faults
• Arc protection
• Protection from overvoltage and undervoltage
• Frequency and frequency change protection for load shedding applications
• Automatic frequency relief for underfrequency load shedding, taking the changed infeed conditions arising from decentralized power generation into consideration
• Configurable power protection (active or reactive)
• Directional reactive power undervoltage protection (QU protection)
• Circuit-Breaker failure protection and reignition monitoring
• Extensive cybersecurity functionality (e.g. role-based access control (RBAC), protocolling security-related events, signed firmware or authenticated network access IEEE 802.1X)
• Reliable data transmission via PRP and HSR redundancy protocols
• 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
• Time synchronization using IEEE 1588
• Provides control of Power Transformers
• Enables powerful fault recording (buffer for a max. record time of 80 sec. at 8 kHz or 320 sec. at 2 kHz)
