This is a safety guidelines document for railway workers.
I was given a definition though: le percharge dans le langage caténaires sert a couper l'alimentation éléctrique dans la zone de travail. 2 perches délimitent de part et d'autre la zone de travail, et les salariés peuvent travailler en toute sécurité, car il n'y a pas de courant dans cette zone

Note: I tried to remember the dedicated term for earthing and short-circuiting procedure I was familiar with during my activity with the German railway and railway engineering offices. Even I searched the internet, no other term was found.
"The greatest challenge in this project was finding a solution for safely and feasibly earthing and short-circuiting the traction current supply lines," reports Jürgen Finsinger, PFISTERER Product Manager for Safety Equipment, "because the usual procedure with standard equipment could not be used in this tunnel." In classic earthing and short-circuiting of open-air railway lines, earthing equipment would be connected so that a train would break it away as it passed (page 6, lower left image). Therefore, in this configuration, the train operation would be regulated according to sections of track.
A mounting bracket and torque-controlled mounting head for the earthing rod make the earthing equipment easy to handle. These features work together ideally during installation: First, the return conductor clamp is put on the earthing rod to hoist and suspend the return conductor. To allow the clamps to withstand the enormous dynamic forces if a short circuit occurs, they are screwed down to the line reliably by means of the earthing rod.
Once a specific torque is reached, the mounting head releases the return conductor clamp, which is now attached optimally, and only after this happens can the installer remove the earthing rod from the clamp.

: Earthing / shorting can only take place once the power has been cut off. / Yes, but the 'perchage' specifically refers to the FIRST action (disconnection), as proved by Didier's ref.

Oui, le perchage (mise à terre et en court-circuit) n‘est effectué qu‘après la vérification de l’absence de tension au caténaire. C’est que j’ai dit et prouvé. // The source term is French, the corresponding English term is asked.

sectionnement
I don't know if this term is used in railways, neither od I know exactly what 'perchage' describes: it might be the action of using a long pole to disconnect the isolator; or more genarlly, the principle of isolating a section of catenary, which is certainly akin to the notion of 'sectionnement' in standard electrical terminology.
--------------------------------------------------
Note added at 47 minutes (2016-09-21 22:00:47 GMT)
--------------------------------------------------
They could, of course, also be EARTHING poles, so that once the power has been isolated elsewhere, the section of circuit is earthed at both ends, so you can be SURE the power won't come back on!
--------------------------------------------------
Note added at 13 heures (2016-09-22 11:02:32 GMT)
--------------------------------------------------
OK, so Didier's very helpful refs. do indeed confirm that this is referring to the use of 'disconnect sticks' to operate the circuit-breakers that will thus isolate a section of line from the power supply; the particular feature of this railway usage seems to be that these insulated operating poles are the left in place as a clear indicator that the circuit has indeed been disconnected.

Oops, Johannes has just pointed out my language error!
OK, so the equivalent term in EN would then be 'isolation'
I HAVE come across 'sectioning' in electrical in EN, but I remain always very wary of this; naturally, one may well be talking about 'isolating power from one section of a system' (particularly applicable when that system is in some sense linear).
But I stand by my original comments: as described in Didier's exactly on-context ref., this is about using poles to operate high-level disconnectors; there is no mention either in the source text or in the reference given about the specific use of earthing poles, which is a different part of the same procedure.

: The UIC lexique mentions "mechanical sectioning, constructional overlap (contact line)" and "sectioning of station tracks" different contexts. // Earthing is not the 1st action, but switching off the OCL, followed by earthing and short-circuiting.

Danke, Johannes! But that's in ENGLISH; this IS a standard term used in HV work in FR! And now Didier has confirmed it does refer to the same action.

cutting (breaking) (turning off) a catenary section
for maintenance purposes
Il existe sur la caténaire des disjoncteurs de chaque côté de la rupture de phase
Section Breaks
Section breaks are gaps in the overhead catenary wires. In this way, each section of catenary can be turned on or off individually.
To allow maintenance to the overhead line without having to turn off the entire system, the line is broken into electrically separated portions known as "sections". Sections often correspond with tension lengths as described above. The transition from section to section is known as a "section break"

Discussion
Pourtant les risques et les accidents existe pour les professionnels comme pour les agents non spécialiste, la preuve :
Années 90, au lieu dit « la Sablière » PK 234 à la sortie faisceau VB-V1, un interrupteur caténaire fond suite à une erreur d’un Surveillant de Tx Voie chargé de Percher.
https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd...
Voilà un exemple de dérive de la sous-traitance qui a vu l'emergence de petites entreprises se spécialisant du jour au lendemain dans la maintenance ferroviaire et dans cette exemple précis bossant avec du matériel non homologué ou défectueux, car avec une perche conforme jamais le courant n'aurait pu être remis.
http://www.cheminots.net/forum/topic/32746-fonctions-dun-con...
“perchage” in narrower sense means only to hook-in the rod. But the context indicates the wider sense: making the contact line dead. This implies the complete procedure. I cite: « le perchage dans le langage caténaires sert a couper l'alimentation éléctrique dans la zone de travail. »
