Country of Origin
This protection relay is engineered and manufactured by ABB Oy in Finland, the global lead center for ABB’s distribution automation products.
Application Fields
The REF615C-D is a versatile unit used for:
- Feeder Protection: Overcurrent and earth-fault protection for outgoing lines in substations.
- Industrial Plants: Protecting internal power distribution networks in oil & gas, mining, and pulp & paper facilities.
- Renewable Energy: Connecting wind farms and solar plants to the distribution grid.
- Automatic Transfer: Managing source transfer logic in dual-feed systems.
- Power Quality: Monitoring harmonics and voltage disturbances on the feeder line.
Product Usage Instructions
- Mounting: Install the relay into the cutout on the switchgear panel. Use the provided mounting clamps to secure it. Since this is a plug-in unit, the case stays wired while the relay unit can be removed for testing.
- Wiring: Connect the CT (Current Transformer) and VT (Voltage Transformer) secondaries to the back terminals. Warning: Never open-circuit a live CT; ensure shorting blocks are used.
- Communication: Plug the RJ45 Ethernet cable into the front or rear port to integrate the relay into the Substation Automation System (SAS).
- Configuration: Use PCM600 (Protection and Control IED Manager) software to set the protection curves (e.g., IDMT or Definite Time) and logic parameters.
- Testing: Perform secondary injection testing using a relay test set to verify the trip settings and the operation of the output contacts.
Product Technical Description
Technically, the REF615 series is native to the IEC 61850 standard, enabling high-speed horizontal communication (GOOSE) between relays for interlocking and sophisticated protection schemes without extra wiring. The “D” configuration specifically indicates support for directional overcurrent and earth-fault protection, which is critical for looped or parallel-fed networks where the direction of the fault current must be known to maintain selectivity. It also features integrated fault recording and an “In-Rush” current detection algorithm to prevent nuisance tripping when energizing transformers.
Q&A (Common Questions)
Q: Can this relay be used for motor protection? A: While it has some overlapping functions, ABB offers the REM615 specifically for motor protection. The REF615 is optimized for feeders and distribution lines.
Q: What is the purpose of the “2” in the configuration code? A: It indicates the power supply range. In this case, it is for low-voltage DC control circuits (24-60V DC). If your substation uses 110V or 220V DC, you would need a different code (typically “1”).
Q: How do I access the fault logs without a PC? A: You can use the front-panel HMI. Navigate to the “Events” or “Disturbance Recorder” menu using the navigation keys to view the most recent trip data and timestamps.
Q: Does it support redundant communication? A: This specific configuration (code ‘A’) is for a single Ethernet port. For redundant communication (HSR/PRP), a different communication module code is required.
