The status (2009) of CERN’s Static Var Compensators and the future role of BEQ1/BB3

As of 1 January 2009, CERNs Static Var Compensators have been transferred from EN-EL to TE-EPC. During 2009, the SVC's will be operated jointly by these two groups. This technical note describes the technical state of the Static Var Compensators (2009), gives an overview of required renovation work and analyses the situation of spare parts. In particular, the document discusses to which degree budgets shall be allocated to maintain and continue to operate the spare SVCs BEQ1 (1974) and BB3 (1982) for SPS. Should we invest in a complete renovation of BEQ1 and BB3, or should we purchase additional spare parts for the modern BEQ2 and BEQ3? The strategy proposed in this technical note has been approved by the IEFC on 4.9.2009.
