KoCoS SHERLOG combines the monitoring functions of a high-class digital fault recorder with the features of a advanced power quality analyser in a single system.

The measuring devices of the SHERLOG range combine the monitoring functions of a high-class digital fault recorder with the features of a power quality analyser in a single system. They can be used to comprehensively monitor power engineering equipment such as lines and bus bars and associated protection devices and switchgear equipment.

Fields of application

SHERLOG systems are suitable for all voltage levels. They can be used as centralized or decentralized monitoring systems and unite the following functions in one device:

  • High-resolution fault recorder for transient processes with sampling rates up to 30 kHz
  • RMS recorder
  • Continuous data recorder
  • Event recorder
  • Power quality analyser to IEC61000-4-30 class A
  • Fault locator
  • Phasor measurement unit
  • Sequence of events recorder Integration in substation control and protection systems to IEC 61850
     

Examples of applications:

  • Digital fault recorder with a high sampling frequency for detailed analysis of transient faults
  • Generator monitoring in power plants
  • Recording and identification of power swings
  • Power quality analysis, e.g. to EN 50160
  • Load and frequency recording
  • Analysis of power consumption
  • Assessment of the capacity utilisation and stability of supply systems
  • Capture of influences resulting from a constantly fluctuating generator and load structure
  • Monitoring of individually agreed connection conditions for compliance with limit values
  • Documentation system for commissioning and service tests
  • Chronological event recording and logging of binary status signals
