Insulect have a conformance monitoring solution that is operating in numerous monitoring applications across the power system
A Brief Update by Henrik Hoff - AP Sensing GMBH
Distributed temperature sensing (DTS) is an established and widely accepted method to monitor the condition of HV and EHV power cables. Thanks to the technology progress, distributed fiber optic sensing has developed further. Enhanced not only in performance and features but also in new techniques that allows measurement of acoustic signals, enabling a spatial distributed hearing into the cable and surroundings.
This paper offers a brief overview about the status of DTS, Dynamic Current Rating (DCR or RTTR) and the new distributed acoustic sensing technology (DAS) as well as details on the world's first combined DTS/DAS installation.
In this document, we take a look at the different technologies available and the advantages they provide networks operators. Companies can use this to evaluate which of these offer the greatest potential gains to their network and model investment scenarios on this basis.
The World Exposition 2010 Shanghai China (Shanghai Expo) was held at the waterfront area on both sides of Huangpu River in Shanghai from May to October, 2010. It brought with it some unique power challenges.
AP Sensing was recently selected toprovide a fibre-optic based Distributed Temperature Sensing (DTS) system to monitor the high-voltage subsea power links between Gedser, Denmark and Rostock, Germany, plus an additional subsea link in Denmark from Orevej to Orehoved.
The Olympic Park is the main center of competition for the 2016 Summer Olympics in Rio de Janeiro. Covering over 1 million square meters and including 9 different sports facilities, a new power substation was constructed to handle the enormous power demand in the park. APSensing’s fiber-optic based DTS (Distributed Temperature Sensing) solution was selected to monitor this valuable infrastructure.
In 2012, when it was time to upgrade and expand their network, Energie Steiermark selected AP Sensing as their DTS solution provider. Two of AP Sensing’s Linear Power Series DTS devices were installed, equipped with Multi Sensor Boards.
In their research laboratory in MORET SUR LOING - Ecuelles, EDF relies on AP Sensing DTS and SmartVision platformforthethermalmonitoringduringtheirhigh voltagecable testing.
In 2009 Brugg Cables installed a new 110 KV power circuit within the city limits of Prague. To protect valuable assets and to gain experience applying Distributed Temperature Sensing (DTS) technology the end customer chose to equip the new circuit with a fiber optical sensor cable and permanently monitor the temperature profile
To monitor and protect the overland sections of this important link, AP Sensing’s fiber-optic based DTS (Distributed Temperature Sensing) solution was selected.
AP Sensing, together with their local partner NEC, were selected to monitor the power cable in a newly-built metro tunnel. This is the first power cable temperature monitoring system to be used in the Taipei MRT.
Oil platform operator Engie needed a monitoring solution for their medium voltage (35kV) subsea power cable, which provides the power for platform operations.
AP Sensing Selected to Monitor and Protect World’s Longest XLPE Subsea Power Link - the best technology for the world's longest power cable!
The Donghai Bridge Wind Farm is located near the Donghai Bridge, Shanghai, which is the second largest bridge in the world. The wind farm was the first commercial offshore wind park, and was completed prior to the 2010 World Expo in Shanghai.
A leading Australian network operator wanted to gain more monitoring insights into their distribution network, to get the most out of their assets and to take advantage of the related operational cost savings
To permanently monitor the temperature along a 220kV power circuit connecting Manhattan (East Harlem) to Queens, USI Power selected AP Sensing’s outdoor DTS instrument.
In 2010 the Tavarnuzze power grid station began operating a new 380 kV power circuit as part of a nation-wide power grid improvement. After three years of successful operation, the grid has been expanded with additional AP Sensing DTS devices
In 2010 a new 380KV power circuit (north/south axis) was put into operation as part of a nation-wide power grid improvement. Near Florence the high voltage circuit has buried sections in close proximity to a very populated valley and a historic church.
A new 220KV underground power circuit in France traverses many different types of soil conditions along its 25 km length and uses AP Sensing’s fiber optic based DTS.
