This is a term that I seem to remember hearing in reference to electric transmission. I'm pretty sure it has something to do with upgrading a set of transmission lines to carry more current, but I'm not totally sure. Am I correct here? Can someone please give a thorough explanation of what reconductoring is?
(electronics) To replace the cable or wire on an electric circuit, typically a high-voltage transmission line, usually to afford a greater electric-current-carrying capability.
TESMEC, an Italian grid infrastructure contractor, provides this description of reconductoring (emphasis added):
Power transmission owners and operators need to develop solutions to maintain the transmission efficiency over time or to increase the capacity of existing lines, that are acceptable to the public, reliable and economical. Reconductoring is the key: renewing the old conductor (line refurbishment) or replacing standard conductors with those of last generation (line improvement).
So your assumption is correct: Reconductoring is the process of replacing the current-carrying conductors in a transmission line, whether to repair aging lines, increase capacity, or both.
