Distributed Temperature Sensing System DTS TOPAZ

Distributed Temperature Sensing System TOPAZ (DTS TOPAZ) is designed for measurement, registration, possessing, display, and transmission to the upper levels the information about continuous temperature profile along the length of connected fiber-optic cable. DTS TOPAZ could be used as a stand-alone solution and as a part of centralized monitoring system of an energy company.


DTS TOPAZ is a complete and ready to use device: it is equipped with components necessary to organize the communication and to ensure the collection and transmission of tele-information in full. DTS TOPAZ is based on the standardized principles of display systems. It has open, scalable and extensible architecture based on IEC standards and open data exchange protocols.

Description

Main advantages of DTS TOPAZ:

  • Detection of events (overheating, breakage, etc.) and their geodetic coordinates;
  • Function of cable line’s load forecast for load balancing  
  • Archive of cable line’s temperature profiles to track the long-term dynamics of temperature anomalies
  • Application in digital substations
