Function and Working Principle
The ABB REF615E operates as an intelligent feeder protection relay that continuously analyzes the condition of medium-voltage electrical networks.
During normal operation, the relay receives electrical measurement signals from current transformers, voltage transformers, and connected field devices. The internal processor evaluates these signals and compares actual operating conditions with configured protection settings.
When a fault condition occurs, such as excessive current, short circuit, or earth fault, the relay quickly identifies the abnormal condition and executes the required protection response. It can issue breaker trip commands, generate alarms, and record fault information for further analysis.
The main operating process includes:
- Collecting electrical measurement data
- Processing real-time feeder information
- Evaluating protection parameters
- Detecting abnormal conditions
- Executing protection and control commands
- Recording operational events
Main functions include:
- Feeder protection
- Overcurrent protection
- Earth fault protection
