Product Description

The REF615E-G is a compact, plug-in type protection relay intended for the protection, control, measurement, and supervision of utility and industrial power distribution systems. It is engineered to support the IEC 61850 standard for communication in substations and provides advanced protection for radial, looped, or meshed power networks.

Product Parameters

Product Advantages

• Plug-in Design: The relay unit can be easily withdrawn from the case for testing or maintenance without disconnecting the wiring, significantly reducing downtime.

• Advanced Earth-Fault Protection: Features sophisticated algorithms for detecting faults in compensated, isolated, and earthed networks.

• Comprehensive Monitoring: Built-in high-accuracy power quality monitoring and disturbance recorder (oscillograph) for post-fault analysis.

• Native IEC 61850: Supports GOOSE (Generic Object Oriented Substation Events) messaging for ultra-fast peer-to-peer communication between relays.

• User-Friendly Interface: Large graphical display for viewing single-line diagrams (SLD), status, and measurements.

Important Considerations & Precautions

1. Correct Configuration: Ensure the application software configuration (Standard Configuration E) matches your specific voltage and frequency protection requirements.

2. CT/VT Secondary Wiring: Always ensure the Current Transformer (CT) secondaries are short-circuited before removing the relay if the plug-in unit is not equipped with automatic shorting connectors.

3. Power Supply: Verify the auxiliary voltage (e.g., 48–250V DC or 100–240V AC) matches the relay’s hardware version to avoid damaging the internal power supply module.

4. Cybersecurity: When connecting to a network, change default passwords and disable unused ports to comply with substation security standards.

Product Applications

• Utility Distribution: Protection of incoming and outgoing feeders in distribution substations.

• Industrial Plants: Power management for large factories, refineries, and mines requiring voltage and frequency stability.

• Renewable Energy: Used in wind and solar grid-tie points where frequency-based load shedding or voltage monitoring is required.

• Infrastructure: Power distribution for airports, hospitals, and high-rise buildings where high reliability is mandatory.
