Tech/Engineering - Energy / Power Generation | | English term or phrase: Portable primary earth | Le document parle du matériel d'une ligne aérienne.
Mon essai : principale terre mobile (qui ne m'inspire pas du tout !)
Toute suggestion sera la bienvenue :)
Merci d'avance et bon week-end ! |

| | équipement mobile de mise à la terre primaire | Explanation:
"Constant or Cyclic? Remember jump leads are short duration items, it is
acceprable for them to heat (Up to a point). Not withstanding anyone elses
point, I have the largest set I can keep in the car along with all my test
instruments. 50mm sq. I have used 150mm in an emergency, but that is
Portable Primary Earth gear for the 33kV Distribution Network. Large
unweildy and you would have no space in the car. (Rated for a fault
capacity of up to 1000MVA. You hopefully don't get that from a combustion
engine alternator!)"

"• Primary Earth
A fixed or portable Earthing Device applied to an Isolated electrical conductor to protect
against inadvertent energisation. Portable Primary Earths must be Approved and have a
cross sectional area of not less than 70 sq mm copper equivalent."

les examples cités montrent clairement qu'il ne s'agit pas de mettre à la terre un appareil portable, mais de mettre à le terre les installations de haute tension sut lesquelles des techniciens travaillent, au moyen d'un "portable earthing device".

"Primary Earth(s) subjected to short circuit fault current shall be inspected for damage prior to re-use. In the case of portable Primary Earth(s) the Senior Authorised Person shall
immediately arrange disposal of the portable Primary Earth(s).
Portable Earthing Device(s) used as a Primary Earth(s) shall not be connected to arcing orns, corona rings, hollow Holtom conductor etc.
Portable Earthing Device(s) used as a Primary Earth(s) may be applied to solid stranded aluminium conductors or internally supported (This can be verified by local knowledge or reference to engineering drawings), tinned, copper, Holtom type conductors."

"When applying portable Primary Earth(s) to braid / shunts the
following shall be confirmed by the Senior Authorised Person
prior to application:-
Braid / Shunt shall have a round profile, refer to Figure
4.1C
Ensure the line end clamp is the correct size for the cross
sectional area of the conductor
Only one portable Primary Earth to be applied to each
braid / shunt
If a short circuit fault was to occur the busbar connector will
require replacement
For work involving line end Equipment it is also recognised that a
potential hazard may exist under certain System configurations
from high circulating currents. In line with Management Procedure
– NSI 4 “Work on or Near High Voltage Overhead Lines” a
substation Drain Earthing Shorting Scheme (DrESS) to the
overhead line entry point may need to be applied.
Where portable Primary Earth(s) have been applied for more than
6 months they shall be replaced in agreement with the Control
Person (Safety). They shall then be quarantined until maintained.
An example of where it is not reasonably practicable to apply a
fixed Earthing Device is a mesh bus section where there are no
fixed Earthing Device(s) by design. As Point(s) of Isolation are
visible from the point of work, the correct circuit can be identified.
Danger from Charged conductors is minimal due to the short
length of busbar. There is therefore a reduced risk and it is
acceptable to apply portable Earthing Device(s), refer to Guidance
Section 7.2 for information on written risk assessments."

en fait le terme technique pour les équipements mobiles de mise à la terre lors de travaux effectués sur les lignes haute tension est "garniture de mise à la terre"

Les garnitures de mise à la terre et en court-circuit doivent être placées à
