Abstract: Pada kebanyakan sistem tiga fasa yang menyuplai beban satu fasa, akan terdapat ketidakseimbangan arus fasa dan arus netral. Arus netral yang besar dapat menyebabkan konduktor netral terbakar, distorsi tegangan dan gangguan pada trafo distribusi. Maka dari itu, penelitian ini melakukan rancang bangun alat sistem otomatis pemutus jaringan tiga fasa berdasarkan pendeteksi arus pada kawat netral. Sistem otomatis pemutus jaringan tiga fasa ini berfungsi untuk memutuskan ketiga fasa apabila ada salah satu fasa yang putus. Komponen yang terdapat pada sistem otomatis pemutus jaringan tiga fasa ini antara lain, mikrokontroler AVR ATMega16, driver relay, penyearah, regulator tegangan dan program BASCOM AVR. Simulasi ketidakseimbangan fasa dilakukan dengan membuka saklar pada salah satu fasa, kondisi ini mewakili gangguan 1 fasa pada sistem tenaga listrik. Setelah saklar dibuka, maka muncul arus pada kawat netral dan akan dibaca oleh driver relay. Selanjutnya driver relay mengirim sinyal ke mikrokontroler untuk selanjutnya memutus semua fasa. Rancang bangun alat sistem otomatis pemutus jaringan tiga fasa berdasarkan pendeteksi arus pada kawat netral ini telah dilakukan pengujian dan telah dapat bekerja sebagaimana mestinya.----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------In most three phase systems that supply a single-phase load, there will be phase and neutral current unbalances. Large neutal currents could cause neutral conductors burn, voltage distortion and fault to the distribution transformer. Therefore, this research performs design of automatic three-phase circuit breaker system based on current detection on neutral conductors.The automatic three-phase circuit breaking system serves to breakall of the three phases if any one phase is broken. Components contained on the automatic three-phase circuit breaking system, inter alia, microcontroller, AVG ATMega16, driverrelay, rectifier, voltage regulator and BASCOM AVR program. The phase unbalance simulation is performed by opening the switch on one of the phases, this condition represent the single line-to-ground (LG) fault in the power system. After the switch is opened, the fault current appears on the neutral wire and will be detected by the driverreal. Hereinafter, the driverrelay sends signals to the microcontroller to further disconnect all three-phases. The design of an automatic three-phase circuit breaking system base on current detection on neutral wire, has been tested and has been able to work properly.
