Function and Working Principle
The ABB RED670 operates as an intelligent line protection relay that continuously monitors electrical conditions of protected transmission lines.
During normal operation, the relay receives current and voltage measurement signals from connected current transformers and voltage transformers. The internal protection processor analyzes these signals and compares electrical conditions between line terminals.
When a fault occurs inside the protected zone, the relay detects abnormal differential current and determines whether the fault requires immediate isolation. The relay then sends trip commands to circuit breakers to disconnect the affected line section.
The basic working process includes:
- Receiving current and voltage measurement signals
- Processing real-time electrical data
- Performing differential protection calculations
- Detecting internal line faults
- Sending breaker trip commands
- Recording fault information
Main functions include:
- Line differential protection
- Phase fault protection
- Ground fault protection
- Fault location support
- Disturbance recording
- Self-diagnostic monitoring
