Abstract
Keandalan sistem tenaga listrik merupakan suatu hal sangat penting dalam keberlangsungan suplai energi listrik ke beban. Apalagi beban yang disuplai merupakan suatu kebutuhan yang vital dalam lini kehidupan manusia. Salah satu bagian penting dalam sistem tenaga listrik yaitu transformator. Menjaga keandalan transformator merupakan suatu upaya untuk membuat energi listrik dapat tersalurkan kepada konsumen dengan baik. Untuk itu diperlukan upaya dalam menilai transformator dalam keadaan baik atau tidak. Dengan menggunakan pendekatan distribusi weibull dapat dinilai bagaimana kualitas tranformator dalam melakukan kerjanya. Dengan melihat bagaimana tingkat rata-rata laju kegagalannya, lalu nilai MTTF nya. dan setelah itu dapat diketahui nilai keandalannya. Semua hal tersebut didasarkan pada jumlah gangguan yang menyebabkan transformator gagal berfungsi. Setelah itu setelah dianalisa bisa diketahui jenis dan presentase kegagalan terbesar yang terjadi pada transformator. Setelah melakukan analisa menggunakan distribusi weibull terhadap transformator distribusi di PT.PLN UP3 SURABAYA SELATANULP RUNGKUT selama rentang waktu dari tahun 2019, 2020, hingga 2021. Maka didapatkan hasil rata-rata laju kegagalan sebesar 18,321894 % / tahun, nilai MTTF sebesar 0,054579 tahun, sehingga nilai keandalan yang didapatkan sebesar 0,981 yang apabila didasarkan pada croanbach alpha maka tergolong pada tingkatan sangat andal. Perlu diperhatikan pula penyebab mayoritas kegagalan transformator adalah kumparan primer terbakar/putus sebanyak 25 kejadian dari total 82 kejadian gangguan. Dengan begitu besaran persentasenya sebesar 30,4878 % dalam kurun waktu tiga tahun.
