Setelah kita memahami apa itu starting DOL dan star delta. Di tulisan ini, saya akan memberikan hasil percobaan motor induksi beserta besar tegangan saat start dan arusnya. Breaker ditulis agar dapat mengetahui berapa besar breaker yang dibutuhkan untuk setiap daya motor. (Ini bukan breaker minimal).

Data berikut diambil dari perusahaan-perusahaan yang mempunyai motor induksi dan bersifat real. Anda harus pahami bahwa keadaan saat di lapangan (praktek) sangat berbeda, jadi ada nilai-nilai yang janggal dari tabel dibawah ini yang tidak sesuai dengan teori.

Hal itu bisa disebabkan karena:

  • faktor manusia yang mengambil data.
  • listrik yang berbeda-beda di setiap perusahaan.

Saya pernah punya kasus ada perusahaan yang motornya memakai breaker A, ternyata tidak kuat untuk starting. Beberapa minggu kemudian teknisi datang lagi dan ternyata bisa dipakai untuk starting.
