An autotransformer (not 'auto transformer') is notnecessarily a variable-output transformer. It merely means that part of its winding is common to both the primary and secondary circuit. Variable-output Transformers, such as the laboratory 'variac', has its voltage-ratio varied by means of a wiper -similar to that of a variable resistor.
yes we can place auto transformer in place of original transformer
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
"Auto" refers to the single winding used an auto transformer.
the auto transformer is the one winding transformer. it ismaily used in practical purpose.
One can purchase an Auto Transformer from websites like Mastech Power Supply, Amazon, Ali Express, RS-Online, eBay, Foster Transformer, Farnell and Alibaba.
(An auto-transformer can be dangerous because the primary is not electrically isolated from the secondary. If the auto-transformer is connected to mains power, this is the equivalent of sticking your fingers directly in the wall plug; not a good idea!) aka deceptacons like megatron will kill you.
by using auto transformer or auto stablizers
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
A mulit tap ballast is in fact an auto transformer.
no.
