Auto transformer is one which have only one winding.

The tappings are taken from secondary for voltage variation.

So not coupled.

Sai said:   1 decade ago
Auto t/f is a device having only one core which is used as both primary and secondary.

Asha said:   1 decade ago
How the tappings are provided ?

Rama Krishna said:   1 decade ago
This is a single core T/F.

Variation of voltage it's automatically tap changed.

Suppose coupled what happen.

Pratiksha said:   10 years ago
