ABB REF615C-D HCFCACABANB2BAN1XD Feeder Protection and Control

The ABB REF615C-D HCFCACABANB2BAN1XD is an intelligent electronic device (IED) for feeder protection and control under the Relion 615 series. Specifically designed for directly earthed or resistance-earthed distribution networks, it focuses on the core protection needs of cable and overhead line feeders. It integrates non-directional overcurrent protection, non-directional earth fault protection, and circuit breaker control functions, while also featuring measurement, monitoring, and communication capabilities. With its compact pluggable design and flexible configuration, it provides a reliable and cost-effective protection solution for industrial power distribution systems.

Core Functions and Advantages

• Comprehensive protection functions: Covering three-stage non-directional overcurrent protection (including instantaneous stage), four-stage non-directional earth fault protection (including sensitive earth fault protection), combined with negative sequence overcurrent protection, phase interruption protection, thermal overload protection and circuit breaker failure protection, comprehensively covering feeder fault scenarios.
• Flexible configuration features: Supports graphical configuration via PCM600 software, allowing adjustment of signal matrices, logic function blocks and I/O connections to adapt to different primary circuit layouts and protection requirements. The default configuration can be directly put into use, reducing engineering commissioning time.
• Accurate measurement and monitoring: Built-in three-phase current and zero-sequence current measurement, equipped with fault recording function, which can record data such as current and status signals during faults, and supports export in COMTRADE format to facilitate fault analysis. It also has status monitoring functions such as trip circuit monitoring and fuse fault monitoring.
• Reliable control capability: Integrates circuit breaker control and automatic reclosing functions, supports switching between local/remote control modes, and cooperates with programmable LED indicators and event records to realize visualization of operation status and traceability of operation trajectories.
• Strong communication compatibility: Supports multiple communication protocols such as IEC 61850 (including GOOSE messages), IEC 60870-5-103, Modbus, and DNP3, and can be connected to substation automation systems. It supports 5 simultaneous online clients to meet horizontal and vertical communication needs.

Key Technical Parameters

• Power supply parameters: The auxiliary power supply supports 48-250 V DC/100-240 V AC or 24-60 V DC, with reverse polarity protection. The power interruption tolerance time is ≥10 ms.
• Input parameters: 3-phase current inputs (1/5 A), 1 zero-sequence current input (1/5 A or 0.2/1 A), 4 binary inputs. The input threshold can be selected from 18-176 V DC.
• Output parameters: 4 high-power trip outputs (PO), 2 signal outputs (SO), supporting circuit breaker opening/closing control, fault trip, and status alarm signal output.
• Environmental adaptability: Operating temperature range of -25 °C to +70 °C, storage temperature range of -40 °C to +85 °C, humidity ≤93% (non-condensing), compliant with EN 61000 series electromagnetic compatibility standards.
• Mechanical characteristics: Adopts DIN rail mounting, with an IP20 protection rating and a weight of approximately 1.5 kg. The modular design facilitates plug-in maintenance.

Application Scenarios and Compatibility

• Applicable scenarios: Suitable for protection of cables and overhead line feeders in directly earthed or resistance-earthed distribution networks. It can serve as primary protection or backup protection, and is widely used in industrial plants, substations, distribution networks and other places.
• Compatible devices: Supports cooperation with ABB PCM600 engineering software (Ver. 2.4 SP1 and above), can be connected to the 800xA automation system, and is compatible with third-party devices that comply with the IEC 61850 standard.
• Configuration adaptation: By default, it supports all functions of standard configuration C. Logical functions can be expanded through PCM600 to meet the customized needs of different users.

Installation and Operation Points

• Installation requirements: Must be installed with current transformers (CT accuracy class is recommended to be 5P/10P, and the actual accurate limit factor ≥20). Wiring must follow terminal definition specifications to ensure correct phase and polarity.
• Operation methods: Supports local HMI (4-line/8-line display optional), Web HMI (browser access) and PCM600 remote operation, with four preset user permission levels: VIEWER, OPERATOR, ENGINEER, and ADMINISTRATOR.
• Maintenance tips: Equipped with self-monitoring function, which feeds back device status through IRF contacts; fault recording and event logs support FIFO storage (2048 system events, 1024 process events), facilitating fault traceability and maintenance.
