Function and Working Principle
The ABB REF615C_D operates as an integrated intelligent relay that continuously monitors electrical system conditions and performs automatic protection operations.
During normal operation, the relay receives measurement signals from connected electrical sensors, including current and voltage transformers. The internal processor analyzes the collected data and compares real-time values with configured protection settings.
When abnormal conditions are detected, the relay identifies the type and location of the electrical disturbance and performs the programmed response. Depending on the protection configuration, it can send trip commands, generate alarms, and record event information for later analysis.
The main operating process includes:
- Collecting electrical measurement signals
- Processing real-time system data
- Evaluating protection parameters
- Detecting abnormal conditions
- Executing control commands
- Recording operational events
