固定配置的故障記錄器與電能品質監測器
SHERLOG CRX 2032 是全球廣泛驗證之模組化測量系統 SHERLOG CRX 的理想補充方案。
在具備相同效能與相同量測與分析功能的前提下，此標準化設備提供了更加緊湊的設計，特別適合用於空間受限的安裝環境。此外，透過標準化設計，無需進行專案客製化生產，可大幅縮短交期並帶來成本優勢。
可配置式故障記錄器與電能品質監測器
由於採用模組化與可擴充的設備設計概念，SHERLOG CRX 可依需求進行配置，並能輕鬆因應新需求進行調整或擴充。即使設備體積精巧，SHERLOG CRX 仍可配置最多 32 個交流/直流類比輸入及最多 128 個二進位輸入。

DIGITAL FAULT RECORDING
SHERLOG – Devices
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.
SHERLOG fault recorder systems for professional event analysis
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:

• High-resolution fault recorder for transient processes with sampling rates up to 30 kHz
• RMS recorder
• Continuous data recorder
• Event recorder
• Power quality analyzer 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 utilization 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

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.
Configurable fault recorder and power quality monitor
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.
SHERLOG Cabinet Systems
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.
