IEEE Transformers Committee Fall 2020
Virtual Meeting
Tuesday, October 20th , 2020
Participants have a duty to inform the IEEE
• Participants shall inform the IEEE (or cause the IEEE to be informed) of the identity of each holder of any potential Essential Patent Claims of which they are personally aware if the claims are owned or controlled by the participant or the entity the participant is from, employed by, or otherwise represents
• Participants should inform the IEEE (or cause the IEEE to be informed) of the identity of any other holders of potential Essential Patent Claims
Early identification of holders of potential Essential Patent Claims is encouraged
Slide #1
Ways to inform IEEE
• Cause an LOA to be submitted to the IEEE-SA ([email protected]); or
• Provide the chair of this group with the identity of the holder(s) of any and all such claims as soon as possible; or
• Speak up now and respond to this Call for Potentially Essential Patents
If anyone in this meeting is personally aware of the holder of any patent claims that are potentially essential to implementation of the proposed standard(s) under consideration by this group and that are not already the subject of an Accepted Letter of Assurance, please respond at this time by providing relevant information to the WG Chair
Slide #2
Other guidelines for IEEE WG meetings
• All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws.
• Don’t discuss the interpretation, validity, or essentiality of patents/patent claims.
• Don’t discuss specific license rates, terms, or conditions.
• Relative costs of different technical approaches that include relative costs of patent licensing terms may be discussed in standards development meetings.
• Technical considerations remain the primary focus
• Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets.
• Don’t discuss the status or substance of ongoing or threatened litigation.
• Don’t be silent if inappropriate topics are discussed … do formally object.

- I have also reviewed the examples. In particular, A1 gives me a lot of headache, since it focusses so much on the internal resonances. In this context it is very speculative I think. The analysis should rather refer to the clauses in the main text than describing the phenomenon with own words. I think example A1 needs a major revision.

Poll Question #5
Changes to Example A5
- Example 5 is also not consistent and should be revised. I think with disconnector switching, which is described in this example, only the steepness of the breakdowns and the high number of breakdowns is decisive. Transformer resonances do not play a role.

Request / Comment from
Switchgear Committee TF Meeting October 6, 2020
There are very fast re-ignition transients that
occur with reactor switching and sometimes with
transformer switching. It is understood that these
very fast transients are not always covered by
standard factory acceptance tests. The
switchgear committee requestor would like to see
some guidance from the transformer and reactor
manufacturers on some realistic limits for these
high frequency transients. These transients can
also damage the switching devices.
