Fault recorder systems with a power quality analyzer for comprehensively monitoring and assessing low, medium and high voltage networks in power plants and transformer substations.
The measuring devices of the SHERLOG range make very high-resolution recordings of all the disturbances which occur in power supply systems. The behavior of protection and switchgear devices during these system disturbances is recorded at the same time.
Multifunctional measuring system with fixed configuration
The measuring instruments of the SHERLOG family combine the monitoring functions of a high-quality digital fault recorder and the features of an energy quality monitor in one system.
SHERLOG CRX 2032
Individually configurable measuring system
Highly modular system for customized customer solutions with maximum availability, it grows with every requirement.
SHERLOG CRX
Customized complete solutions for stationary use
Fully assembled and tested cabinet solutions for direct installation in customer systems.
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 analyzer 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:
Examples of applications
Fault recorder and power quality monitor with fixed configuration
The SHERLOG CRX 2032 is the ideal complement to our globally proven modular measuring system SHERLOG CRX.
With the same performance and identical measuring and analysis functions, these standard unit offers an even more compact design, which is ideal for use in confined spaces. In addition, this standardization eliminates the need for project-specific production, which leads to significantly shorter delivery times as well as cost advantages.
Equipment features:
SHERLOG CRX 2032
Thanks to the modular, scalable device concept, SHERLOG CRX can be equipped as needed and easily adapted or expanded to meet new requirements. Despite its compact dimensions, SHERLOG CRX can be equipped with up to 32 analogue inputs for AC and DC measurements and with up to 128 binary inputs.
For monitoring extensive systems, individual units can be networked via an interlink interface.
Plug & Play-Technology
Extensions and configuration changes can be carried out easily and quickly due to the plug & play technology. Even the replacement of the analogue measuring modules is possible without time-consuming and cost-intensive adjustment, as the calibration data is stored on the modules.
Equipment features:
Slots to accommodate:
In addition to the measuring systems themselves, KoCoS also offers completely assembled and tested cabinet systems. These are individually designed and manufactured according to customer specifications. Of course, after successful commissioning and individual configuration of the systems, an on-site or remote maintenance service is also included in the range of services.
EPPE vs. SHERLOG
Compact precision for grid analysis and fault recording
The EPPE system from KoCoS offers high-precision power quality and power measurement analysis with integrated fault recorder functions. EPPE is designed for the comprehensive monitoring of one bay. Ideal for municipal utilities and medium-sized installations, it combines power quality analysis and transient recording in one compact device. With sampling rates of up to 200 kHz, 32 GB memory and conformity to VDE-AR-N-4110/4120, EPPE is the perfect solution for detailed power quality analyses and fast fault localization in medium-voltage grids and EEG systems.
