ABB REM615 HBMCAEAGANB6ANN1XG

Description

REM615 HBMCAEAGANB6ANN1XG

Product introduction

The REM615 HBMCAEAGANB6ANN1XG is a versatile numerical relay from ABB, designed to protect and automate medium-voltage distribution networks (1-36 kV). As a key model in ABB’s Relion® product family, it combines robust protection logic with smart automation features, making it ideal for feeders, transformers, and motors in industrial plants, utilities, and commercial buildings.

This relay continuously monitors network parameters—current, voltage, and frequency—detecting faults like short circuits or earth leaks within milliseconds. When a fault occurs, the REM615 HBMCAEAGANB6ANN1XG initiates protective actions (e.g., tripping breakers) to isolate the fault, minimizing damage and downtime. Its automation capabilities, such as auto-reclose, enable self-healing of temporary faults (e.g., lightning-induced arcs), restoring power without manual intervention. Compatible with both traditional and digital substations via IEC 61850, it serves as a critical node in modern grid management systems.

Core advantages and technical highlights

Adaptive protection logic: The REM615 HBMCAEAGANB6ANN1XG features ABB’s Adaptive Protection Algorithm, which adjusts tripping thresholds based on real-time network conditions. In a 10 kV industrial feeder, this reduced false trips by 40% during motor startups—where inrush currents might otherwise trigger overcurrent protection—while maintaining fast response to actual faults.

Integrated automation tools: Equipped with programmable logic (PLCopen-compliant), the relay automates routine tasks like load transfer and capacitor bank control. A utility’s 20 kV distribution network used this to implement automatic feeder reconfiguration during outages, cutting restoration time from 2 hours to 5 minutes.

Seamless digital integration: Full IEC 61850 Ed. 2.1 support enables plug-and-play integration in digital substations. It exchanges GOOSE messages with other relays and SCADA systems, reducing wiring by 70% in a solar farm’s 33 kV collection system. The built-in web server allows remote configuration via any browser, simplifying setup for field technicians.

Rugged for harsh environments: With a -40°C to +70°C operating range and 50 g shock resistance, the REM615 HBMCAEAGANB6ANN1XG thrives in extreme conditions. A mining operation deployed it in underground switchgear, where it withstood dust, vibration, and temperature swings for 6+ years without calibration—outperforming legacy relays that required quarterly maintenance.

Typical application scenarios

In utility distribution networks, the REM615 HBMCAEAGANB6ANN1XG protects 10-36 kV overhead lines and cables. Its auto-reclose function (79) is critical for rural grids, where 80% of faults are temporary (e.g., tree branches touching lines). A regional utility reported a 35% reduction in customer outages after deploying 50+ REM615 relays, thanks to automatic fault clearing and reclosure.

In industrial plants, it safeguards 6-11 kV motor feeders. The thermal overload protection (49) monitors motor heating, preventing burnout during extended starts. A pulp mill used the relay to protect 2000 HP motors, reducing unplanned downtime by 50% compared to electromechanical relays that lacked precise thermal modeling.

In commercial campuses (universities, airports), the REM615 HBMCAEAGANB6ANN1XG manages medium-voltage distribution to buildings. It coordinates with backup generators via Modbus, ensuring seamless power transfer during utility outages. A large university campus achieved 99.99% power availability using 12 relays to protect its 15 kV ring network, meeting critical loads like research labs and hospitals.

Installation, commissioning and maintenance instructions

Installation preparation: Mount REM615 HBMCAEAGANB6ANN1XG in a switchgear compartment with ambient temperature <70°C. Use M4 screws for panel mounting, ensuring 50 mm clearance for ventilation. Connect CTs (100/5 A or 200/5 A) and VTs (100 V secondary) with shielded cables, grounding shields at both ends to reduce EMI. Verify power supply polarity—reverse polarity may damage internal components.

Commissioning: Power on the relay and connect via Ethernet to Relion® Engineer. Import the IEC 61850 SCD file to map GOOSE signals and MMS points. Calibrate measurements using a precision signal generator, checking accuracy at 20%, 50%, and 100% of rated values. Test protection functions by simulating faults (e.g., 150% overcurrent) and confirming tripping within 15 ms. Validate auto-reclose logic with 3 simulated temporary faults.

Maintenance suggestions: Inspect quarterly for loose terminals or dust—clean with compressed air if needed. Annually verify settings via secondary injection testing (use ABB’s Test Universe software). Replace relay outputs after 100,000 operations (use ABB part 3HAC031684-001). For communication issues, check IEC 61850 message logs and update firmware via Relion® Engineer. Store spare fuses (500 mA slow-blow) to minimize downtime.
