Patents:
The WG Chair provided an opportunity for participants to identify patent claims, patent application claims, or patent application claims of which the participant is personally aware and that may be essential for the use of this standard.
No patent claims, patent application claims, or holders of patent claims or patent application claims have been identified at this time
Minutes:
1. Introduction and calls for patent by Mohamed Chaaban, there was no response. It is assumed that no one knows any patent related to the guide.
2. The group Chair reminded the participants that the PAR would expire in 2011. This is the last opportunity to review the contents and correct omissions or to add any new information that has been developed or discovered since the first version.
3. Review the latest draft version of the Guide for Temperature for Monitoring of Cable System.
a. Since the OMEGA company have not provided their permission to include their drawings the proposed fig 1 and 2 were removed and replaced with our own design.
b. A new addition to the Chapter 6.1 was proposed to reflect two DTS technologies – OTDR and OFDR. After lengthy discussion and opposition from some DTS manufacturers this paragraph showing relation to any technology was deleted.
4. Fiber optic darkening was also discussed. According to John Downes its degree of influence depends on the laser wavelength. An appropriate warning was introduced in the guide.
5. As an extension of an earlier discussion about the position of the fiber sensor relative to the power cable Chris Grodzinski showed two pictures of a circuit failure. The circuit has the working DTS system installed but its fiber optic sensor was installed remotely (in the adjacent duct) and did not cover the cable in the joint bay. As such the system could see the increased temperature.
6. Chair asked the working group members that greater participation is expected to finalize the draft before next spring. The latest version of the draft will be posted on ICC web page.
7. The meeting was adjourned at 10:30.
