Applications

The fault recorder is for use in medium, high and extra-high voltage systems 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 quality of supply
• Dynamic behavior of generators
• Closing and breaking operations of transformers (saturation Response)
• Power fluctuations and power-swing cycles
• Test runs during commissioning

Benefits

• Clearly organized documentation and focused analysis of power system processes and failures
• Data security and transparency over the entire lifecycle of the plant save time and money
• Purposeful and simple operation of the devices and software thanks to user-friendly design
• Increased reliability and quality of the engineering process
• Powerful communication components ensure safe and effective solutions
• Full compatibility between IEC 61850 Editions 1 and 2
• Highly available Ethernet communication due to integrated Ethernet redundancy protocols PRP and HSR
