T2F is supplied by the NP24 substation. To meet the needs of added load there is a change in the electrical system configuration in T2F where before the change in the NP23 substation network is supplied from MSA or MSB the MSA goes to MSH and MSB leads to MSA at NP24 substation and forms a loop 1 at Terminal 2 and at NP22, previously MSB leads to MSO then MSA leads NP21 substation and forms a loop 2 in terminal 2 in the terminal to meet airport electrical binding requirements and improve reliability on the electricity network in terminal 2. To simulate the protection system ETAP 12.6.0 application is used to get the results Lvmdp,Sdp,Dan Mvdp short circuit 3 phasa Ocr Incoming Transformator Tms = 0.28 Outgoing Transformator Lt= 0.5,Cb Primerpump Lt= Class 5,Cb Pp Sekunder Pump = Class 5,Cb Condeser Pump = Class 5,Cb Colling Tower= Class 5, Cb Sdp Ahu = Class 5,Cb In Sdp1= Class 5,Cb Out Sdp = Class 5,Dan Untuk Penyetelan Di Bagian Sdp Menggunakan Magnetic Thermal Fixed.Dp Tenant = Fixed,Cb Pp Wing = Fixed,Cb Pp Wing B2 Ltd = Fixed Lp Main Building = Fixed.} }
