For two major North European utilities ( Fingrid Oyj and Svenska Kraftnät ) LIOS Technology provided its most advanced multimode Distributed Temperature Sensing (DTS) systems to monitor the HVDC subsea link between the two utility grids. The electricity transmission connection is crossing the Gulf of Bothnia between southern Finland and Sweden.
The Fenno-Skan 2 HVDC project creates a new 800 MW, 500 kV subsea electricity transmission connection following a 200 km route.
It forms a bipolar arrangement with the existing 550 MW, 400 kV Fenno-Skan link, commissioned in 1989, providing a 40 % increase in power transmission capacity between the two countries.
The DTS systems provide real time distributed temperature sensing of the HVDC interconnecting subsea cable and land cables on both sides ensuring a save and stable grid operation.
DTS are Distributed Temperature Sensing systems which measure temperatures by means of optical fibers functioning as linear sensors.

The Brazilian National Study Committee of Cigré B1 – Insulated Cables – is going to promote an International Workshop on Insulated Cables “ Workshop Internacional Sobre Cablos Eletricos ” , this year in São Paulo, Brazil.
The workshop taking place 20 – 22 June 2011, will be composed of short tutorials with international specialists on the following subjects:
- State of the art of technologies for maintenance of underground transmission lines (138 kV and above). The preferential methodologies that will be focused will be: measurement of partial discharges in field, detection and localization of small oil leakages in OF cables, and other maintenance edge technologies.
- Monitoring of underground transmission lines in real time: distributed temperature, current capacity, partial discharge, etc.
- Methods of calculation of magnetic fields of underground transmission lines and mitigation of magnetic fields generated by underground facilities.
- New technologies for high voltage cables and accessories: high-temperature superconductors, hybrid joints, Y joints, "plug in" joints and terminations.

私たちはあらゆるやり方で温度をとります。 – 光ファイバ温度分布計測システム – DTS
DTS(光ファイバ温度分布計測システム) |
LIOSテクノロジー は、自社のDTS(光ファイバ温度分布計測システム)製品を様々なビジネスセグメントにおいて流通し、関連したアプリケーションや地理上の地域において、優勢なプレーヤーと提携してきています。LIOS テクノロジーは、積極的にセンサー技術を以下の垂直市場セグメントにおいて展開しています。 既に世界中で 2000以上の永久システム設置に成功しています。 :
- トンネルや特別危険建物の中での火災検知
- 高圧ケーブルとトランスミッションライン監視
- 石油ガスの探索-永久ダウンホール監視
- 産業用誘導電気炉の監視
- 液化天然ガスキャリアーとターミナルの完結性
- 堤防とダムでの漏水検知
- プラントと技術過程における温度監視
テクノロジー
LIOS テクノロジーは、リニアセンサーとして機能する光ファイバ−によって温度を測定する分散温度センサー(ラマン DTS)システム を生産しています。温度はセンサーケーブルに沿って点ではなく、継続したプロファイルとして記録されます。測定時間は短いのですが、高精度な温度決定が長 距離であろうと広大な表面積であろうと、確実になされます。
