how winding temperature detects in power transformer...?

Answer Posted / ullas

a special CT(current transformer ) is used to measure the
winding temperature in a power transformer.
the method is very simple, there will be one winding
temperature measurement pocket in the transformer. in this
a temperature measurement device is dipped and this pocket
will be filled with transformer oil. this special CT will
give output in the form of current which is proportional to
the temperature.
i think this makes a clear picture.
