Applications
The fault recorder is for use in medium-voltage systems, highvoltage systems, and systems for very high voltage and in power plants with comprehensive trigger and recording functions. With the SIPROTEC 7KE85 fault recorder, you receive a clearly organized and event-related evaluation and documentation of your power-system processes. You are thereby able to analyze failures in a targeted manner and optimize your power system. Typical processes to be monitored and documented:
- System incidents, such as critical load cases or short circuits
- Failures of the supply quality
- Dynamic behavior of generators
- Closing and breaking operations of transformers (saturation response)
- Power fluctuations and power-swing cycles
- Test runs during commissioning
