		abstract={Protection failure in the distribution station so that the protection on the rework is generating losses in PLN. The failure to protect the protection of the substation should be analyzed, look for causes and take steps to anticipate the
protection failures in the booths. In the SR-52 garage, the addition of CT with large capacity to anticipate the occurrence of protection failure in the garage, comparing the current CT saturation flow with additional CT. In the SR-052 line with IHB data of 10 kA, based on the result of calculation of the CBOG CT Congenital obtained its ICT at 160.65 A until IHB > ICT means that CT will be saturated so it can not work or fail protection. Meanwhile, in an additional protection CT with ICT of 17,320 A to IHB < ICT means that CT will detect short circuit current and will occur tripping coil will work. As for the sealing of the relay on the built-in CT CBOG and CT protection additional is obtained the same setting result i.e. Iset OCR 20.81 A, Iset MOC 104.05 A, Iset GFR 2.31 and Iset
MGF 11.55 A. With the addition of A large capacity CT will be able to detect the large current Without saturated and reduce the occurrence of protection failures.}
