  The pro­tec­tion sys­tem for su­per­con­duct­ing mag­nets and bus-bars is an es­sen­tial part of the LHC ma­chine pro­tec­tion and en­sures the in­tegri­ty of sub­stan­tial el­e­ments of the ac­cel­er­a­tor. Due to the large amount of hard­wired and soft­ware in­ter­lock chan­nels the de­pend­abil­i­ty of the sys­tem is a crit­i­cal pa­ram­e­ter for the suc­cess­ful ex­ploita­tion of the LHC. The paper will re­port on ob­served fail­ure modes, pre­sent fault statis­tics and dis­cuss the over­all per­for­mance of the pro­tec­tion sys­tem dur­ing LHC op­er­a­tion in 2010 and 2011. Fore­seen mea­sures for fur­ther im­prove­ments and op­er­a­tional re­sults ob­tained with al­ready im­ple­ment­ed sys­tem up­grades will be de­scribed.
