Discussion Overview
The discussion centers around the definition of synchronous reactance for a cable, with references to its application in electrical circuits, particularly in relation to synchronous machines and short-circuit impedances.
Discussion Character
- Technical explanation
- Debate/contested
Main Points Raised
- One participant references a paper that includes a section on determining short-circuit impedances, suggesting it may clarify the concept of synchronous reactance.
- Another participant expresses unfamiliarity with the term "synchronous reactance," indicating it appears in the referenced paper.
- A different participant states that synchronous reactance is defined specifically for synchronous machines, describing it as the ratio between the EMF induced in the stator and the short-circuit current at the same excitation level.
Areas of Agreement / Disagreement
Participants express differing views on the applicability of synchronous reactance, with some suggesting it is specific to synchronous machines while others imply it may relate to cables as well. The discussion remains unresolved regarding a consensus definition.
Contextual Notes
There is a lack of clarity on the definitions and contexts in which synchronous reactance applies, particularly concerning its relevance to cables versus synchronous machines.

The paper linked has the section 2.2 Determining the various short-circuit impedances.
Hopefully, that will answer your questions. If not, you need to be more specific about which rectance you mean.

Interesting, I'd never heard that term before, "synchronous reactance", but there it is in the paper!

likewise, but then, am not into high power motors or generators for which this seems to apply toD

In my humble opinion, no synchronous reactance is defined for any part of a circuit except synchronous
machine: the ratio between EMF induced in the stator and short-circuit current at the same excitation level.
