Anti-islanding relay UFR1001E ( Ziehl )

Introducing the Anti-Islanding Relay UFR1001E by Ziehl for Victron Inverters, an essential component to secure NRS approval for installations utilizing non-compliant inverters with NRS regulations. The UFR1001E is a state-of-the-art dual-channel device designed to monitor voltage and frequency in electricity generation plants, ensuring a reliable and safe operation.

Key Features:

1. Dual-Channel Redundancy: The UFR1001E boasts a dual-channel configuration, providing a fault-proof system. This redundancy ensures continuous monitoring even in the event of a fault in one channel, enhancing the overall reliability of the relay.
2. Output Relay and Switch Monitoring: The device allows for the monitoring of output relays and connected switches through feedback contacts. In the event of a switch failure to either turn on or off, the UFR1001E takes corrective actions to maintain the integrity of the monitored plant.
3. Voltage Monitoring:
   • Under and overvoltage monitoring ranging from 15 to 520 V.
   • Option for measuring phase-neutral or phase-phase voltages, offering flexibility in diverse electrical configurations.
4. Frequency Monitoring:
   • Under and over-frequency monitoring spanning 45 to 65 Hz.
   • Robust monitoring of the rate of change of frequency (ROCOF) within the range of 0.100 to 5,000 Hz/s, ensuring precise control.
5. Quality of Voltage Monitoring:
   • Continuous monitoring of the quality of voltage through a 10-minute average, contributing to the stability and reliability of the electricity generation plant.
6. Vector Shift Monitoring:
   • Monitoring of vector shift in the range of 2 to 65 degrees, allowing for a comprehensive assessment of the electrical parameters.
7. Zero Voltage Monitoring (ANSI 59v0):
   • Robust monitoring of zero voltage (U0) according to ANSI standards, further enhancing the protective features of the relay.
8. Passive Anti-Islanding Protection:
   • Adheres to chapter 6.5.3 and appendix D2 specifications, providing passive anti-islanding protection to meet regulatory requirements.
9. South Africa Certification:
   • The UFR1001E comes with a Certificate of Conformity (NRS 097-2-1:2010 1.0), attesting to its compliance with South African standards and regulations.
