ABB RET615E E Transformer Protection Relay – Original

ABB RET615E E Transformer Protection Relay (Industrial-Grade IED)

The ABB RET615E E is a dedicated transformer protection Intelligent Electronic Device (IED) from ABB’s renowned 615 Series. Engineered for power utilities, industrial substations, and critical infrastructure, this relay delivers comprehensive protection, monitoring, and control for two-winding power transformers. Whether you’re safeguarding distribution networks or managing complex substation automation, the RET615E E provides the reliability and precision your operations demand.

Designed to meet both ANSI and IEC standards, the RET615E E integrates seamlessly into modern digital substations, supporting IEC 61850 GOOSE messaging, MODBUS, and DNP3 protocols — making it a future-proof investment for grid modernization projects.

Core Features & Benefits

• ✅ Comprehensive Transformer Protection: Differential (87T), overcurrent (50/51), earth fault (50N/51N), restricted earth fault (64REF), and thermal overload (49) protection in a single IED
• ✅ IEC 61850 Edition 2 Compliant: Supports GOOSE messaging and MMS for seamless substation automation integration
• ✅ Dual-Rated Voltage Inputs: Flexible configuration for various transformer winding ratios and system voltages
• ✅ Advanced Disturbance Recording: Built-in fault recorder with up to 100 disturbance records for post-event analysis
• ✅ Compact Panel-Mount Design: 4U rack-mount form factor minimizes panel space while maximizing functionality
• ✅ Wide Operating Temperature Range: -10°C to +55°C continuous operation for harsh industrial environments

Application Scenarios

The RET615E E addresses real-world protection challenges across multiple industries:

• Power Utilities & Grid Operators: Protects distribution and sub-transmission transformers (11kV–110kV) against internal faults, overloads, and external disturbances — reducing unplanned outages and SAIDI/SAIFI penalties
• Industrial Plants (Oil & Gas, Mining, Petrochemical): Safeguards critical process transformers where downtime costs exceed equipment value; integrates with DCS/SCADA via MODBUS RTU/TCP
• Renewable Energy Substations: Protects step-up transformers in wind and solar farms, with fast differential protection to minimize fault clearing time and protect inverter equipment
• Data Centers & Critical Facilities: Ensures continuous power supply by providing redundant protection for main and tie transformers in N+1 configurations
• Railway Traction Substations: Handles asymmetric loading and harmonic-rich environments typical of traction power systems

Frequently Asked Questions

Q: What is the difference between ABB RET615E E and RET615C?
A: The RET615E E includes Ethernet communication (IEC 61850 Ed.2) and an expanded protection function set compared to the RET615C, which uses serial communication only. The E E variant is recommended for new digital substation projects.

Q: Can the RET615E E protect autotransformers or three-winding transformers?
A: The RET615 is optimized for two-winding transformers. For three-winding or autotransformer applications, ABB’s RET670 series is recommended. Contact our team for application-specific guidance.

Q: Is the ABB RET615E E compatible with IEC 61850 Edition 2?
A: Yes. The RET615E E fully supports IEC 61850 Edition 2, including GOOSE messaging, MMS reporting, and SCL-based configuration via PCM600.

Q: What auxiliary power supply voltage does the RET615E E require?
A: The relay accepts a wide range of auxiliary voltages: 24–250V DC or 100–240V AC, making it compatible with most substation battery systems and UPS supplies.

Q: How do I configure the RET615E E for my specific transformer ratio?
A: Configuration is performed using ABB’s PCM600 tool. Our technical team can provide pre-configured parameter files based on your transformer nameplate data — simply share your transformer datasheet when placing your order.

Q: Does NINERMAS offer testing or calibration services for the RET615E E?
A: We supply factory-tested units with full functional verification. On-site commissioning support and relay testing coordination can be arranged upon request.
