1. Introduction and calls for patent by Mohamed Chaaban

2. Review the draft version of the Guide for Temperature for Monitoring of Cable System. There are a few pictures that require either source or permission to include in the guide.

3. Added Deepak Parmar to the group membership.

4. Chair asked if there is any standard that includes testing a transmission type cable with integral fiber for the purpose of temperature monitoring. There was no response.

5. Chris Grodzinski presented an initial draft/proposition for the fiber acceptance test. Jay Williams agreed to prepare a preamble on using this appendix. The appendix is marked as “Appendix A” in this guide draft.

6. Chris Grodzinski presented Appendix B for mechanical cable tests for the sole purpose of evaluating protection of the fiber. The appendix will be posted on ICC web page for further review and corrections. The proposed appendix is included in the minutes.

7. Sudhakar Cherukupalli presented a sample of specification for the purchase of the DTS. The specification included a form for filling by a manufacturer with guaranteed system performance values. The sample specification is not included in the minutes but it will be provided to members after permission is granted.

During installation the cable is subjected to several, very often severe, mechanical forces. It is unknown if the fiber position, maximum recommended pulling tensions, bending radius and/or sidewall pressures do not cause any damage to the fiber and cable insulation. The fiber damage could be either mechanical or optical or both. The damage would cause increase in the fiber attenuation. Damage to the cable insulation or its jacket should be revealed by the forensic study.

The purpose of this test is to replicate installation conditions.

The tests specified below are recommended but they should be agreed to between a user and manufacturer. (?? Routine tests or a part of qualification test ) They should be performed in addition to any test required by applicable standards. The sequence of test should also be agreed between the user and manufacturer (if routine tests).

1. Test preparation

A sufficient length of cable should be cut from a randomly selected part of a production run. The minimum recommended length for this purpose should not be shorter than 30m. The length, however, must be calculated for the concentric neutral type of cables where the fiber optic cable is helically applied to include at least 10 turns of the fiber.

Both cable ends should have pulling eyes installed in such a way as is recommended for installation of this type of cable. The fiber must be available for testing at both ends.

2. Tensile (stretch) test.

The tensile test of the cable depends on the type of the conductor material, its size and cable construction. The maximum applied pulling forces should not be less than those recommended in relevant standards as the maximum pulling stress plus 10%. The test duration shall not be shorter than 10min.

3. Torsion tests

The torsion test is intended to replicate the cable behavior during pulling operation during which the cable rotates along its longitudinal axis.

To perform this test one end of the cable sample should be adequately and safely installed to prevent its rotation. The other end of the cable sample shall be rotated five times in both directions for at least 90° from its normal unstressed position.

4. Pressure test

The pressure test force of at least 110% of the recommended sidewall pressure but not less than 5kN/m should be performed on a piece of cable of at least 1m length. The pressure faces shall be rounded and bent. The round shall have radius of 1.5 times the cable overall diameter and the bending radius shall be not more that 20 time cable diameter (see Fig 1). The pressure should be applied against the sides of the cable where the fiber is located. The test duration shall not be less than one minute.

If the cable construction contains more than one pair of optical assemblies the test shall be repeated for each pair.

5. Optical tests

Optical test shall be performed on each fiber before the tests begin and after each type of tests. The procedures to conduct such test are described in 6.3.2. All test results shall be recorded and evaluated according to Appendix A. The cable is considered to pass the tests if any of the value does not exceed those specified in Appendix A.

Since the cable sample is short from the optical measuring point of view an additional length of fiber not less than 500m shall be added at both ends for the purpose of attenuation measurement.

6. Other tests

1. Since the conflict of two group meetings it was decided that the groups C01D and C24W would seat together.

2. 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.

3. It was reminded to the participants that the PAR would expire next year. Chair will ask the SA officers to confirm the expiry date.

4. Review the draft version of the Guide for Temperature for Monitoring of Cable System.

a. There are a few pictures that require either source or permission to include in the guide. Rusty Bascom will pursue OMEGA permission to include their pictures in the guide.

b. Mohamed Chaaban presented permission from CIGRE to include part of their guide that was written and updated. Pierre Argaut who is the chair of the CIGRE group and working member of the C24W confirmed the permission.

5. Chair asked the working group members that greater participation that is expected to finalize the draft before next spring.

6. There is a need for a sample specification. Sudakhar Cherukupalli will prepare.

7. Discussed Chapter 7 – User Interface

a. Comments from John Downes were reviewed and most of them accepted. Editorial corrections were introduced to make this chapter more general.

b. Dennis Johnson agreed to review and correct/edit chapter 7.

8. Since the ICC spring meeting is early next year Chris Grodzinski asked for the return of all comments within three weeks that would allow for issuing a new version for the final discussion before the end of 2009.

9. The meeting was adjourned and subject changed to Ampacity Topics.
