Kesimpulan Berdasarkan hasil studi dan analisis koordinasi rele pengaman pada sistem kelistrikan Bandara Internasional Juanda Surabaya yang telah dilakukan, maka dapat diambil beberapa kesimpulan sebagai berikut: 1. Terdapat beberapa setelan rele yang belum tepat dan koordinasi yang kurang baik, terutama pada setelan pickup dan grading time antar rele pengaman. Pada beberapa rele, setelan pickup kurva inversnya masih menyentuh arus full load beban. Hal ini dapat menyebabkan rele tersebut trip meski tidak terjadi gangguan. 2. Grading time yang diberikan terlalu sempit, yakni 0,1 detik. Hal ini dapat menyebabkan koordinasi yang kurang baik sebab ada kemungkinan rele backup juga ikut trip karena tidak memberikan waktu yang cukup untuk rele pengaman utama selesai memutus ganguan terlebih dahulu. 3. Dari kesalahan eksisting rele arus lebih yang kurang terkoordinasi, maka diperlukan pengaturan ulang untuk mencapai koordinasi yang baik.
