isolation transformer is basically used 4,isolate between to
electrical ckts and the turns ratio is always 1:1.

Answer / zahid ali

Dear Friend
Isolation transformer is used between two circuits for
Galvanic isolation. It is used to prevent the damage on the
source circuits, Like PLCs, DCS etc. in case of field
circuit shorted.

Answer / afrooz

isolation transformer is used to ups from damaged if there
any fault in the feild

Answer / tariq

Isolation Transformer is used to block the DC components.
It has 1:1 ratio.There are many causes to produce/introduce
the DC components. If we do not block these components then
if may effect on the output. Isolation Transformer can be
used within in a single circuit. So, it is not correct that
the isolation transformer is always used to isolate the two
circuits.

Answer / sasi karthick a

Isolation transformers are used to isolate the two sides of
the system with respect to electrical and introducing a
transformer will bring down the short circuit fault level
because of transformer impedance.

Tats y lighting transformer are considered even though for
same level of voltages.

Answer / suppu

isolatin transformer is used for reduse the leakage current
