is it possible to step down voltage of single phase from a
three phase sysem? explain
Answer Posted / y.vidya sagar
Yes, we can use autotransformer connection or tappings on
one phase to get the reduced voltage in one particular
phase while all the other phases give the same magnitude of
voltage as before to the load. As the tapping is varied we
can get the variable voltage.

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.
