North Area Maintenance weeks and AUG tests Feedback from users & lessons learned Additional activities for EN-EL contractor List of activities and follow-up EN-EL calendar LS2 planned maneuvers D. Bozzini on behalf of EN-EL, 13 October 2020
North Area Maintenance weeks and AUG tests Feedback from users & lessons learned
Feedback from users & lessons learned
EN-EL invited to report on North Area maintenance and AUG tests at
the ENTM planned for Thursday 15 October 2020
Request made to main users and stakeholders to provide feedback
on the four following topics
Affected systems
Malfunctions (causes, consequences and measures taken)
Coordination and planning
Suggestions for improvement
Valuable feedback received so far from:
F. Duval (EP)
J. Devine (EP) draft in approval state
TI (BE)
Presentation to EATM after ENTM conclusions and recommendations

Examples of maintenance activities
Maintenance 18 kV Magrini switchgear
– General Services network
4 switchgear, 35 feeders, dating
from 70’, includes busbars &
ground switch-disconnectors
Last maintenance performed in
2005, should be done every 10
Before After
yrs.
100% completed
Switchgear dangerous to operate,
requiring maintenance < 10 yrs.
“Risque de désaxage des volets
en ferraille engendrant un court-
circuit franc pendant les
manœuvres de consignation”
“Remplacement visserie HS sur connexion
secondaire transformateur de courant (TC)
dans EMD2/A82, risque d’explosion du TC”
4
Examples of maintenance activities
Scheduled corrective intervention on a LV switchboard (sub-distribution) following visual
inspection and routine visits performed during machine operation
“Risque de mauvaise
connexion dans le temps,
départ de feu”
Before After
Consolidation AUL system in EHN1 following malfunctioning observed by EP in August 2020
Replacement of one tripping coil
and three circuit breakers
5
Actions initiated and planned to be done during LS2
Study for replacement of the following UPS systems
EBS21/BL4
EBS22/A81
EBS21/A85
EHN1
Replacement of batteries of the following UPS systems (already part of the EN-
EL program)
EBS21/A80
EBS24/A80
EBS21/A81
EBS24/A81
EBS21/A82
EBS24/A82
EBS21/B81
Completion of 48V system in EHN1

Additional activities for EN-EL contractor List of activities and follow-up
List of activities and follow-up
Goal is to grant a sufficient workload to EN-EL contractor
Identification of activities that can be done in the coming months,
according to infrastructure availability and accessibility
Common EN-EA / EN-EL table for regular update and follow-up at the
EATM and/or EACM
