I. Model Affiliation and Product Positioning

Model Affiliation: The REF615C_C belongs to the ABB Relion series of digital protection relays, specifically designed for transformer protection and control in medium and high-voltage power systems. It is an upgraded model of the REF615 series.
Product Positioning: As an Intelligent Electronic Device (IED), it integrates transformer differential protection, backup protection, measurement, control, and communication functions. It supports applications in traditional substations and digital substations (IEC 61850), suitable for protection scenarios of power transformers with voltage levels from 10kV to 220kV.

II. Detailed Technical Parameters

Parameter Category	Detailed Specifications
Protection Functions	- Main Protection: ▶ Transformer differential protection (ratio braking characteristic, supporting inrush current identification and CT saturation detection) ▶ Harmonic braking (secondary harmonic suppression for inrush current misoperation prevention) ▶ Differential instantaneous protection (fast action for severe faults) - Backup Protection: ▶ Overcurrent protection (three-stage directional overcurrent, zero-sequence overcurrent) ▶ Overvoltage/undervoltage protection, overexcitation protection ▶ Temperature protection (supporting winding/oil temperature sensor access) ▶ Gas protection (gas relay signal access) - Auxiliary Functions: ▶ Circuit breaker failure protection, automatic tripping logic, non-electric quantity protection (pressure relief, abnormal oil level, etc.).
Measurement and Metering	- Real-time monitoring of parameters such as three-phase voltage, current, active/reactive power, frequency, power factor, etc., with a measurement accuracy of ±0.5% - Supports electrical energy metering (active/reactive), compliant with IEC 62053-22 standard, with a resolution of 0.01kWh - Fault recording: Records 10 cycles before and 50 cycles after a fault, with a sampling rate of 2000Hz, supporting COMTRADE format export.
Communication Interfaces	- 2× Ethernet ports (supporting IEC 61850-3, Modbus TCP, EtherNet/IP) - 2× RS-485 serial ports (supporting Modbus RTU, IEC 60870-5-103) - GOOSE/SMV message transmission (adapted to sampled value and tripping signal transmission in digital substations) - Supports optical fiber interface (optional) to enhance anti-interference capability for long-distance communication, compatible with IEEE 1588 network time synchronization (synchronization accuracy ≤1ms).
Power Requirements	- Input voltage: 110-220V DC or 110-240V AC (wide-range compatibility), power consumption ≤30W - Supports dual-power redundant input to improve system reliability, with surge protection design.
Physical Characteristics	- Dimensions: 190mm×210mm×150mm (standard 19-inch rack mounting) - Weight: Approximately 3.5kg - Protection class: IP20 (panel), suitable for indoor control cabinets, supporting rail or panel mounting.
Operating Environment	- Temperature: -25°C to +70°C (wide-temperature design without fans) - Humidity: 5% to 95% (non-condensing) - Vibration/impact resistance: Complies with IEC 60068-2-6/2-27 standards, adapting to strong electromagnetic interference environments in industrial fields (EMC class complies with IEC 61000-6-5).

III. Core Functions and FeaturesSpecialized Transformer Protection Design

Optimized Differential Protection: Supports multi-side differential protection (phase correction for Y/Δ connected transformers), with built-in inrush current identification algorithm (adjustable secondary harmonic braking coefficient) to avoid misoperation during transformer energization.
Integrated Non-Electric Quantity Protection: Directly accesses non-electric quantity signals such as gas relays and pressure relief valves to achieve comprehensive monitoring of transformer oil level, oil temperature, and internal faults.
Overexcitation Protection: Calculates through the V/Hz ratio to prevent core saturation and overheating caused by transformer overvoltage or low-frequency operation.

Digitalization and Communication Capability

Supports the IEC 61850 communication protocol, enabling docking with Merging Units (MUs) and Smart Terminals (STs), adapting to digital substation architectures;
Supports GOOSE fast tripping signal transmission (response time ≤2ms) to meet the need for rapid transformer fault removal.

Convenient Human-Machine Interaction and Debugging

The front panel is equipped with a 4.3-inch color touchscreen, supporting real-time data display, modification of protection settings, and query of event records (storing up to 1,000 events);
Achieves graphical programming through ABB Relion® configuration tools (such as Relion 600 Series Manager), supporting configuration of custom logic blocks (such as ladder diagrams, function block diagrams).

Reliability Design

The hardware adopts a dual-CPU redundant architecture, and key circuits (such as sampling and tripping circuits) undergo dual verification to prevent misoperation and refusal to act;
Built-in self-checking functions (CPU status, memory, communication link monitoring), supporting regular self-testing, compliant with IEC 61508 functional safety standards.

IV. Application Fields

Power Systems: Protection for 10kV~220kV main transformers, station transformers, and distribution transformers;
Industrial Scenarios: Protection for large power transformers in metallurgy, petrochemicals, mining, and other industries (such as blast furnace transformers, rectifier transformers);
Renewable Energy: Protection for step-up transformers in wind farms/solar power plants and grid-connected transformers in energy storage stations;
Critical Facilities: Transformer protection in scenarios with high requirements for power supply reliability, such as data centers, hospitals, and rail transit.

V. Typical Configurations and NetworkingTraditional Substation Mode

Connects CT/PT (current transformers and voltage transformers on each side of the transformer) and circuit breakers through hardwiring, receives non-electric quantity signals such as gas relays, and realizes protection functions.

Digital Substation Mode

Accesses MU (Merging Unit) via optical fiber to receive sampled values (SMV), controls circuit breaker tripping through GOOSE messages, and communicates with the substation control layer system (SCADA).

System Integration

Docks with ABB Ability™ smart grid management systems to achieve transformer condition monitoring (oil chromatographic analysis, winding temperature trends), fault early warning, and intelligent dispatching.

VII. Common Faults and Maintenance SuggestionsDifferential Protection Misoperation

Check whether the CT transformation ratios and polarities on each side match the transformer wiring (such as Y/Δ wiring phase correction parameters);
Confirm whether the differential protection settings (ratio braking slope, inflection point current) match the transformer capacity, and whether the secondary harmonic braking coefficient is reasonable (default 15%~20%).

Communication Interruption

Check network cable connections and switch port status, and test network connectivity using the ping command;
Confirm whether the device IP address, MAC address, and GOOSE control block configuration in the IEC 61850 configuration file (SCD) are correct.

False Alarm of Non-Electric Quantity Protection

Check whether the wiring of gas relays and temperature sensors is loose or moisture-affected;
If there is an abnormal oil level alarm, verify the actual oil level of the transformer on site and eliminate sensor faults (such as float jamming).

VIII. Selection and Configuration Notes

Transformer Parameter Matching: Configure differential protection parameters according to transformer capacity, voltage level, and wiring mode (Y/Δ, Y/Y), with special attention to CT transformation ratio conversion and phase correction;
Non-Electric Quantity Signal Access: Confirm the type of non-electric quantity input supported by the device (dry contact/analog quantity). If oil temperature sensors (such as PT100) need to be accessed, configure the corresponding analog input module;
Digital Substation Adaptation: If used in digital substations, confirm the MU sampling rate (such as 4000Hz) and GOOSE tripping message format with the design institute in advance.
