can we use the step down transformer to step up transformer..

Answer / j.karthik

ya,its possible.. for ex: using a 11kv/415volt step down
transformer, in this primary voltage is 11kV and the
secondary voltage is 415volt(step down transformer)... now
we giving the input voltage to the 415volt side of the
transformer now the primary voltage is 415volt and secondary
voltage is 11kV(step up transformer).....
The step up and step down transformer is deponds upon
the input voltage is feeding side of the transformer(Primary
or secondary side)

can we use the step down transformer to step up transformer..

Answer / lokeshraj

Yes we can use this in both step up and step down. But the
transformation ratio is not same in both case. It would be
slightly different.

can we use the step down transformer to step up transformer..

Answer / akatugba

On the issue of reversing step down as step up....Do you
ever put the 4poles into consideration..What now happen to
the grounding for protection, is the 4th pole for grounding
going to be on the 11kV outgoing? or on the incoming
415volts

can we use the step down transformer to step up transformer..

Answer / manoj

no, b'coz step up & step down t/f is design perposly,it
depend on wdg,for step down no of pri wdg more sec wdg
less,& for step up no of pri wdg is less & no of sec wdg is

3 Answers Blue Star,

on 22.03.2015 at 17:15hrs Y phase 66kV class Power Trf-2 Current transformer has flashed over and oil came out. The failed CT has been replaced on 24.03.2015 at 13:15hrs and the Trf has been charged in presence of RT Hassan after conducting the pre-commissioning tests. On the same day at 17:00hrs the commissioned CT has again flashed over and immediately the Trf has been isolated from power supply. It is confirmed the secondary is not opened and checked the earth integrity and is found ok. Here what would be the reason for the CT failure?
