9 Advantages of remote powering: -Safer long-term operation of powering equipment (power converters, current leads and associate auxiliary devices) located in a radiation-free environment; -Safer access of personnel to equipment for maintenance, repair, diagnostic and routine tests interventions; - Reduced time of interventions on power converters, current leads and DFBs if the powering equipment is located outside of the tunnel areas gain in machine availability ; - Free space in the beam areas which becomes available for other equipment.
