Optimum Utilization of Energy Transmission Backbone in Eastern Europe

Optimum Utilization of Energy Transmission Backbone in Eastern Europe

LIOS Technology successfully provided an integrated thermal monitoring solution for a strategically important interconnection aerial line in Eastern Europe.

The LIOS DTS system was supplied to provide distributed temperature measurement by means of a fibre integrated into a replaced optical phase conductor (OPPC). The picture above shows a straight joint of the OPPC.

The DTS covers the entire 17 km range of the three-core bundle 400kV transmission line. The applied Optical Frequency Domain Reflectometry (OFDR) principle ensures a temperature survey even over long distances at the decisive spatial resolution of 1 m.
It provides an invariant spatial resolution along the entire sensor length and a satisfactory temperature resolution of less than 1°C, which ensures early identification and clearly measurement of atypical hotspots (e.g. tower shadows). In addition to the phase conductor temperature, the electrical and metrological data are integral parameters for the established dynamic rating system (RTTR). All data are made online available through the SCADA system of the utility.

The integrated monitoring solution generates:

  • Safety - Avoid and respond appropriately to critical load situations
  • Optimization  - Utilize the existing grid capacity to an optimum
  • Dynamic and Flexibility - With dynamic rating to a flexible energy backbone
