YETS : open points Request from TE-EPC: upgrade of the SVC Control System in LHC PA6 Project background: Installation and commissioning of a new control crate for the Static Var Compensator in LHC PA6. The existing control system is from 1988, and has become obsolete. LHC PA6 is the prototype installation. Once the new control crate is validated there, we will apply it for all our SVCs. Description of our request: We need to ask EN-EL to switch off the main 66 kV transformer in LHC PA6 for 1 or 2 days This requires the transfer of the load in PA6 to the LHC 18 kV General Services Loop (switch-over and switch-back of the load) Transient disturbances possible during these two periods. Main impact on the following groups: EN-EL, EN-CV, TE-CRG, Others LHC coordination meeting 12th December 2017

YETS : open points Request from TE-EPC: upgrade of the SVC Control System in LHC PA6 Planning: At the latest, we need to commission the new system in the second half of January 2018. Possible dates for the switch-over on PA6 for TE-EPC: December 2017 Week 2/2018 or Week 3/2018 (latest date ) Maybe we can find a way to do the switch-over / switch-back manoeuvre during AUG tests which would disturb the LHC load anyway? Outlook: Pre-commissioning in Week 4/2018 Powering tests in Week 5 or 6/2018. During the powering tests, some smaller disturbances are possible in the 18 kV network in PA6 Coordination with the users in PA6 are also required to find the best slot for the powering tests.
