French term or phrase: dérivation par picage (d'une ligne HT)
Hi all !
I am hoping that someone can help me with this expression. Context is a Project for the Rehabilitation and Extension of Electrical Networks.

"2. Consistance du projet :

Fourniture et installation de :
• 201 km de réseau basse tension (torsadé NFC 33-20970 mm2 et 35 mm2) ;
• 95 km de réseaux moyenne tension 15, 20 ,30 kV (Amelec 54,6mm2 et 75 mm2) ;
• 72 transformateurs hauts de poteau 100 et 160 kVA ;
• 12 postes de distribution MT/BT équipés de cellules HTA, transformateurs 400 kVA TUR et EP ;
• 1 poste de transformateur 110/30 kV de 5MVA composé d’une travée transformatrice et d'une travée de ligne simplifiée, y compris la réalisation des bâtiments (logement de service, logement d’habitation du chef de poste et loge gardien), la réalisation des travaux de génie civil de la sous station (massif, fosse, clôture, drainage etc.) et la fourniture et pose des équipements électriques de la sous tension (appareillage extérieur, tertiaire des bâtiments, contrôle commande, supervision, détection incendie).
• La ******dérivation par picage****** d'une ligne HTB/110kV. Ancrage sur pylône existant ainsi que la fourniture et pose d'un nouveau pylône HTB intermédiaire pour le raccordement du poste de transformation décrit ci-dessus.
• Dépose du réseau existant dans les localités de X, Y et Z.

Any help is greatly appreciated !
Cheers,
Jeff

tapping a HV/110kV line


Explanation:
Tapping may be treated as an intrusion, be it direct or indirect, on a well configured, nicely operating, and stable transmission line, and then analyzed for its effect on the steady-state, transient and dynamic performance of the grid particularly with respect to power flow, protection, security, and contingency plans.

Electric power may be tapped straight from the high voltage transmission lines either for consumption to meet the needs of rural and remote areas, and telecommunication establishments located in remote sites; or as a scheme to enhance the capacity of another utility or grid along a trans-national or trans-continental transmission corridor.


Example sentence(s):
  • Long distance point-to-point HVDC link which traverse rural dwelling places can be utilized for tapping power to feed those areas.

neutral  Daryo: "Tapping may be treated as an intrusion" .... yes. it could be, if it's done illegally to nick electricity, but that's not the case in this ST.
15 hrs
  -> The legal nature of the entire project is crystal clear, and the definition refers to legal tapping as well. It says ''Tapping MAY BE'' and not IS...The subsequent operations referred to in the parag suggest the type of tapping the author refers to.

A branch line (connected to a HV power line)


Explanation:
Should be piquage


Routledge Technical:

dérivation: (réseau) branch, branch line

piquage: the entry mentions branch, but in relation to a different subject area

The first entry does also mention "ELECT (raccordement) tapping", but why get bogged down with that when the context provides the meaning.


A branch line obviously draws power off the main line, that's why it's called a branch line, in the same way that trains "turn off" a main train line onto a branch line.

I realise that this is a common-sense, non-technical solution, but I do think that it gets the job done.

Maybe at least it will kick off a conversation and/or some more alternative ideas.

I add this note to my answer with the rider that I am contributing as a non-specialist in this subject area. But I do know how to research terms and I do understand the basic situation, as will become apparent.


33 internet search matches for "dérivation par piquage":

https://www.google.co.uk/search?q="dérivation par piquage"&e...

This tells us that it is a VERY rare term in French.


Ideally, tap/tapping should appear in the correct answer, but the other answers posted so far have not convinced me -- I've run the searches. I do appreciate that not EVERYTHING is on the internet, but most things are.


So, as I understand the set-up, as a non-specialist, the "branch line" draws off electricity from the main high voltage line, then runs that electricity through a sub-station ("poste de transformation" in the bullet point in question, "poste de transformateur" in the bullet point above it), which converts it to a lower voltage, on the way to the end user.


So I conclude that my answer adequately describes the basic set-up, if possibly not the technical bits that are part of the exact process involved.


With my solution, the contractor (the text is almost certainly part of a contract or of a call for tenders) will understand the message that the text is trying to convey, and will be aware of the regulatory standards involved (as Daryo points out in his Discussion post), so job done as far as I'm concerned, pending a credible expression involving tap or tapping.

To Jeffrey: you're welcome, it's always interesting to have a dip into specialist areas I'm not that familiar with. The Discussion might have gone on for a "while" had I not got things started!

disagree  Daryo: you forgot the "par picage" part // you don't get to enjoy ANY kind of "poetic licence" with this kind of texts - you have belles-lettres for that.
