5Review and approval of the notes from the last meeting [especially actions taken]

The unapproved minutes of the November 12, 2013 teleconferencewere posted November 12, 2013 on the SPDC Forum. An E-mail was sent to members asking them to review the minutes, and forward any comments to the Chairman.

6Review of homework assignments from last meeting:

Al to update PC62.36 Draft 16 to show the changes to the Ratings and Characteristics clauses as proposed in the meeting [done]

Al to incorporate the material in clauses 4 and 5 of C62.43 into the related Background clauses of C62.36[done]

Ernie to contribute proposed text for revising clauses 8.4 and 8.5 in PC62.36 Draft 16 [clauses 7.14 and 7.15 in draft revised at this meeting [not done]

7Chair’s Remarks

7.1WG Scope

1.Develop and recommend standard methods for testing and rating surge protective devices. [C62.36 – revision in progress]

2.Prepare sections defining the characteristics and recommended application criteria for these devices for incorporation into the Low Voltage Surge Protective Devices Application Guide. [C62.43]

3. Establish performance characteristics for surge protective devices packaged to be connected to low voltage communications and signaling circuits for multiple component combinations of linear or non-linear elements. [C62.64-2009]

4.Coordinate and incorporate sections prepared by other groups for single devices.

8Old business: Continue work on C62.36 as needed

8.1PAR as approved 2/5/2010 [expires 12/31/2014]

Scope of Proposed Standard:This standard applies to surge protectors for application on multiconductor balanced or unbalanced data, communications, and signaling circuits with voltages equal to or less than 1000 V rms, or 1200 V dc. These surge protectors are designed to limit voltage surges, current surges, or both.

This standard describes the methods of testing and criteria for determining the end of life of electrical surge protectors used in low-voltage data, communications, and signaling circuits. The surge protectors covered are multiple-component series or parallel combinations of linear or nonlinear elements, packaged for the purpose of limiting voltage, current, or both.

This standard is not intended to cover packaged single gas tube, air gap, varistor, or avalanche junction surge-protective devices, which are covered by IEEE Std C62.31, IEEE Std C62.32, IEEE Std C62.33, and IEEE Std C62.35, respectively.

Specifically excluded from this standard are test methods for low-voltage power circuit applications. For protection of wire-line communication facilities under the specialized conditions found at power stations, consult IEEE Std 487.

Purpose of Proposed Standard: This standard provides a detailed set of performance and end-of-life tests for multiple-component surge protectors.

Need for the Project: C62.36-2000 [a reaffirmation of C62.36-1994] has been widely used in the telecommunications industry, but is now significantly out of date. It needs to be reviewed, and test methods added, deleted, merged, or revised to reflect current practice and improvements resulting from the use of the Standard.

8.3C62.36 status

Waiting for RevCom approval

9New business: Roadmap to future work

9.1Initiate a Task Force to propose revisions PC62.36

  • At the last meeting the WG discussed the question of which clauses should be Characteristics and which should be Ratings. Based on the practice in GR974 the suggestion was made to move PC62.36 Draft 16 clauses 7.1 and 7.5 to Ratings, and move clauses 8.9 – 8.17 to Characteristics
  • Check references in the revised text.
  • Consider moving the material in C62.43 clauses 4 and 5 to C62.36
  • Consider new tests or modifications to existing ones

9.2Initiate a project to revise PC62.36

After PC62.36 publishes, get a PAR to:

  • Move PC62.36 Draft 16 clauses 7.1 and 7.5 to Ratings, and move clauses 8.9 – 8.17 to Characteristics
  • Move the material in C62.43 clauses 4 and 5 to C62.36, if the WG agrees
  • Add new tests, if any
  • Modify existing tests, if needed

9.3Form a Task Force to plan the future of C62.43 and C62.64

  • Possibly replace C62.43 and C62.64 with a document titled something like: Applications Guide and Preferred Values for Test Methods for Surge Protectors Used in Low-Voltage Data, Communications, and Signaling Circuits
  • Assuming the material in clauses 4 and 5of C62.43 has been moved to C62.36 per 9.1 above, delete these clauses. Then:
  • Annex A: Is it needed, or would a reference to k.applspd be adequate?
  • Annexes B – F: Keep as is, delete, revise?
  • What material in C62.64 should be incorporated into the new standard?

9.4Initiate a project to revise C62.43 and C62.64

9.5C62.36 Addendum [new item for future consideration]

Due to the rapid advance of technology, C62.36 should be updated probably once a year. Rather than open the standard every year, it may be appropriate to issue addenda until it is time to revise C62.36. If anyone has an idea for a new test, or a revision to an existing one, we could consider it here.
