Atunci când tensiunea primară este mai mare decâttensiune secundară, atunci transformatorul se numește autotransformator pas cu pas, iar atunci când tensiunea primară este mai mică decât secundar, atunci se numește auto-transformator step-up. Autotransformatorul are un cost redus, mai bunregulament și pierderi reduse.

A ∆ – ∆ autotransformer connection is theoretically possible; however, this will create a peculiar phase shift. The phase shift is a function of the ratio of the primary to secondary voltages and it can be calculated from the vector diagram. This phase shift cannot be changed or eliminated and for this reason, autotransformers are very seldom …
Transformator Autotransformator Variabel. solusiindustri. Transformator autotransformator variabel ini sebenarnya sama seperti trafo biasa. Hanya saja sadapan tengahnya dapat diubah – ubah sehingga memberikan perbandingan antara lilitan primer dan lilitan sekunder yang berubah – ubah. 5. Transformator Isolasi
3. Transformator Autotransformator. Keunikan trafo autotransformator dibandingkan trafo lainnya adalah hanya mempunyai satu lilitan saja. Pada trafo autotransformator, kumparan primernya sebagian merupakan kumparan sekunder juga dan lilitannya dibuat dari bahan kawat yang lebih tipis dibandingkan jenis trafo lain.

An autotransformer has several numbers of voltage tapings with voltage ranging between 50% to 80%, which gives a different amount of output voltage to be supplied to the motor. The starter circuit has three switches labeled 1, 2, and 3, which control when the motor should operate under limited or full voltages.
