ABB RET650 Transformer Protection
Description
ABB RET650 is an intelligent electronic device (IED) designed for reliable protection and control of two- and three-winding power transformers.
Features
- Future-proof design for flexible application in new and retrofit installations
- Unmatched sensitivity and fast fault detection
- Reduced parameter settings with pre-configured defaults
- Enhanced HMI with dynamic LED indicators and configurable shortcuts
Technical Specifications
- Implements IEC 61850 standard for interoperability
- Up to 3 user pages with 15 dynamic three-color LEDs per page
- Equipped with negative sequence internal/external fault discriminator
- Low impedance restricted earth-fault function for all earthed windings
- Directional zero-sequence current criterion enhances security
- Overcurrent functions provide backup protection
- Thermal overload function prevents damage from overheating
- Breaker failure protection enables high-speed tripping
- No need for interposing CTs or harmonic stabilization
- Fast differential protection with high sensitivity for turn-to-turn faults
- Designed for low primary CT requirements
- Factory-tested with full functionality and default parameters
- Supports rapid commissioning with application-specific setting examples
