Applications
The REU615E-E is a cornerstone component in medium-voltage distribution infrastructure:
- Overvoltage and undervoltage protection
- Frequency protection and load shedding
- Protection of capacitor banks and reactors
- Supervision of voltage regulation in industrial substations
- Integration into smart grid automation via IEC 61850
Usage Instructions
- Mounting: Install the relay in a clean, dry, and vibration-dampened panel. Ensure the locking mechanisms are fully engaged to maintain the enclosure’s environmental rating.
- Wiring: Connect voltage transformer (VT) inputs to the rear terminal blocks. Follow the project-specific wiring diagram carefully, ensuring phase polarity is correct to prevent maloperation.
- Communication: Connect the relay to the station bus using the integrated Ethernet or serial ports. Ensure proper termination if the relay is part of a daisy-chained network.
- Configuration: Use the PCM600 engineering software to load the application configuration. Define the relay protection setpoints and control logic via the software interface.
- Testing: Before putting the relay into service, perform secondary injection testing using a test set to verify trip times and threshold settings for all active protection functions.
Frequently Asked Questions (Q&A)
Q: What is the benefit of the “E-E” designation?
A: This typically refers to the specific hardware configuration and functional software bundle pre-loaded for voltage-centric protection applications within the Relion 615 family.
Q: Can this relay be used for directional power protection?
A: The REU615 is primarily focused on voltage-based protection. If directional power protection is required, verify if your specific hardware configuration supports these additional logic functions or consider the REF615 series.
Q: Does the relay support remote firmware updates?
A: Yes, firmware updates can be managed through the PCM600 tool, allowing for feature enhancements or security patching while the relay is in the control environment.
