Powering the Transfer Lines TI2 and TI8

Electrical power for the transfer tunnels will be distributed from the LHC side and the SPS side. For the injection tunnel TI2, buildings LHC SR2, SPS BA6 and BA7 will be used to house the power converters and MV/LV switchboards. Galleries and ducts will facilitate cabling between power transformers and converters. For TI8, buildings LHC SR8 and SPS BA4 will be used. MBI magnets will be powered by water-cooled cables whilst rest of the magnets will be powered by conventional copper and aluminium cables. A load of 16.15 MVA and 30 MVA was intended for the existing SPS 18 kV pulsed loop by TI2 and TI8 respectively. The main compensator associated with this loop will almost reach its capacity with the load of TI2 alone. Therefore a new 18 kV pulsed link from Prevessin to BA4 will be installed, compensated by the third compensator. This paper explains how the above tasks will be achieved.
