ABB REM615E-G Measurement and Control Relay

Description

ABB REM615E-G Measurement and Control Relay

The ABB REM615 is a dedicated motor protection and control relay designed for the protection, control, measurement, and supervision of asynchronous motors in manufacturing and process industries. It is part of the Relion® product family and belongs to the 615 series.

The “E-G” designation typically refers to a specific hardware/software configuration (Standard Configuration E) optimized for motor protection with voltage-based protection and additional functionalities like RTD inputs.

1. Key Product Parameters

2. Main Protection Functions

The REM615 offers comprehensive protection for both startup and stall conditions:

• Motor Startup Supervision: Prevents damage during prolonged starts.

• Thermal Overload Protection: Uses a sophisticated thermal model to protect the motor insulation.

• Negative Phase Sequence Protection: Detects phase unbalance and broken conductors.

• Loss of Load: Detects shaft breakage or pump dry-run.

• Voltage Protection: Overvoltage, undervoltage, and frequency protection (critical for large motors).

3. Product Advantages

• Compact & Modular: The plug-in design allows for easy maintenance and quick replacement without disconnecting the wires.

• High Flexibility: Ready-made standard configurations (like “E”) reduce engineering time while remaining customizable.

• Native IEC 61850 Support: Includes GOOSE messaging for horizontal communication between relays, reducing hardwiring.

• Safety Features: Includes specialized protection against internal arc faults and extensive self-supervision of hardware and software.

• Web-based HMI: Allows users to access the relay settings and event logs via a standard web browser.

4. Product Applications

The REM615 is widely used in sectors requiring high-reliability motor control:

• Oil & Gas: Protecting heavy-duty pumps and compressors.

• Water & Wastewater: Controlling submersible pumps and treatment fans.

• Power Generation: Protecting auxiliary motors in power plants.

• Mining & Metals: Managing conveyors, crushers, and mills.

5. Important Considerations (Precautions)

[Caution] High Voltage Hazard: Ensure the relay is properly grounded before powering up. Never disconnect the CT (Current Transformer) secondary circuit while the primary side is energized, as this can generate lethal voltages.

• Firmware Compatibility: Ensure the PCM600 (Protection and Control IED Manager) version matches the relay’s firmware version for configuration.

• Environmental Protection: While the front is IP54, if used in extremely dusty or corrosive environments, ensure the relay is housed in a properly ventilated NEMA/IP-rated cabinet.

• CT/VT Ratio: Accurately input the Current Transformer and Voltage Transformer ratios during commissioning; incorrect values will lead to nuisance tripping or failure to trip.
