The REF615 is a dedicated feeder protection and control relay designed for the protection, control, measurement and supervision of utility substations and industrial power systems. As part of the ABB Relion 615 series, this device provides standard configuration C, which is specifically tailored for applications requiring comprehensive overcurrent and earth-fault protection with additional voltage and frequency measurement capabilities. The REF615 integrates numerical protection functions, local human-machine interface (LHMI) displays, programmable light-emitting diodes (LEDs), and extensive communication capabilities into a single compact unit. It supports native implement of the IEC 61850 standard for communication in substations, as well as Modbus TCP/IP, Modbus RTU, DNP3, and Profibus using optional communication modules. The relay handles current and voltage inputs via instrument transformers, executing real-time monitoring and trip logic to ensure the stability and safety of distribution networks.
| Parameter | Specification |
|---|---|
| Manufacturer | ABB |
| Product Series | Relion 615 series |
| Model | REF615 Standard Configuration C (REF615-C) |
| Rated Frequency | 50 / 60 Hz |
| Current Inputs | 4 (3 phase + residual) |
| Voltage Inputs | 3 or 5 (depending on explicit variant configuration) |
| Communication Protocols | IEC 61850, Modbus TCP/IP, Modbus RTU, DNP3, Profibus |
| Local Interface | LCD, 3 LEDs (Protection indicators), 11 Programmable LEDs |
| Configuration Software | PCM600 Protection and Control IED Manager |
| Approximate Weight | 3.5 kg |
| Dimensions (W x H x D) | 177 mm x 177 mm x 201 mm |
The relay must be mounted securely into a cutout panel using the provided mounting brackets and screws. Ensure proper clearance is maintained around the rear enclosure to facilitate adequate natural cooling and air ventilation.
Connect the dedicated grounding terminal on the rear of the device chassis directly to the substation earth bar using a heavy-gauge copper wire. All communication cables, especially serial links like RS-485 and Ethernet copper lines, must use high-quality shielded twisted-pair (STP) cables with the shields grounded properly to minimize electromagnetic interference (EMI).
Separate low-voltage signal wires and communication cables from high-voltage primary current transformer (CT) and voltage transformer (VT) secondary wiring. Ensure all binary inputs and signal outputs are terminated correctly according to the connection diagram provided with standard configuration C, verifying correct polarity for all DC auxiliary supply lines.
