why autotransformers are not safe for supplying low voltage
from a high voltage source?
Answer Posted / sidharth
An autotransformer doesn't provide electrical isolation between its windings like an ordinary transfomer. hence, the maximum limit for voltage transformation in an autotransformer is 3:1. beyond this value, it is safer to use a 2 winding transformer.
