Description
F35-V00-HKH-F8L-H6M-MXX-PXX-UXX-W7C UR series protective relay
Product Description
The integrated digital relay shall provide protection, control, monitoring and measurement for up to 5 feeders (with one bus voltage measurement) or 6 feeders (without bus voltage measurement) and shall be suitable for integration in a substation integrated automation system.
Protection function
Overcurrent protection
Delay overcurrent elements should be provided: for phase to phase, neutral and ground currents (2 TOC elements per CT set, up to 6)
Delay overcurrent characteristic curves should be provided: IEEE, IEC, IAC, I2t, fixed time and user-defined curves (for accurate matching or complex matching).
Instantaneous overcurrent elements shall be provided: for phase to phase, neutral and ground currents (2 IOC elements per CT set, up to 12)
Sensitive ground
A sensitive grounding input should be provided to detect ground faults occurring in high-impedance grounding systems.
Voltage protection
Two phase undervoltage elements shall be provided for each voltage input of the relay.
Auxiliary undervoltage and overvoltage elements shall be provided for each voltage input of the relay.
A neutral overvoltage element shall be provided for each voltage input of the relay.
Frequency protection
6 underfrequency elements shall be provided for load rejection protection
Product parameter
- Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE, IEC 61869 or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
- Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
- High-end fault and disturbance recording, including internal relay operating signals
- Advance Cyber security features “CyberSentryTM” that helps meet modern industry requirements
- Simplified system integration with communications supporting serial and Ethernet interfaces and multiple protocols
- Supports latest edition of waveform capture (COMTRADE 2013) simplifying fault records management
- Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
- An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors
Application field
- Primary protection and control for multiple distribution feeders
- Distribution load shedding schemes based on voltage and frequency elements
- Busblocking/interlocking schemes
- Throwover schemes (bus transfer scheme applications)
- Distributed generation (DG) interconnect protection, including active and passive anti-islanding
