Answer / vijay
Breather are used to absorb the moisture content from the
sucked air, while the transformer oil gets expanded due to
heating. Breathers make use of silica gel coloured with
blue used extensively in power transformers.
when its absorb moisture its colour change and become whit

Answer / raghvendra kumar
Breather is basically work as an indicator to show the
moisture content in transformer oil. Usually its normal
colour is blue but after absorption of moisture content its
colour changes into pink which shows a moisture content in
transformer oil which is unacceptable.
Used Silica gel can be reused after passing it to heat after
which it regains its original Blue colour.

Answer / zain abbas-tuf
Basically breather is a chamber located in large sized transformers where complete air tight is impossible in order to suck the moisture that tries to contaminat with oil for cooling purpose.

Answer / navin jain
breather is used to intake fresh air in the transformer tank for cooling purpose. The air is contaminated with moisture which may enter the tank and forms sludged with the insulation papers inside the tank and prevent free circulation of oil into the tank there by raising the temperature inside the tank. Therefore silica gels are provided in the breathers which absorbs the moisture content from the air.

Answer / aditya
breather r used in two places... wid the transformer and
with the conservater tank too.... when... oil level..
decreases after a certain time due to.. heating..air... gets
filled in the gaps.... which could contain... moisture..
this moisture... is removed by the...silica gel.. by
soaking.. it... here it.. works as an absorbant...... it is
max. found to be in blue or purple colour... its not of just
a single colour.. it could be of any colour... after
absorbing its colour gets... light... and it can be
recycled... again.. by drying it!!!!!... it plays an
important role.. in avoiding.. any short circuit... in the
transformer.....
do correct my answer... if it has any mistakes....
thankx!!!!!!!

Answer / pwikamau
Power transformers those are not haematically sealed have
breathers to facilitate free flow of the air into
tranformer oil to faciliatte cooling. In order to ensure
that there is no aculation of mositure in the transformers,
which could lead to explosion and/or short circuit as a
result of steam accumulation, selica gel is put in a
trasparent glass mounted on the oil tank of the
transformer. Selica gel which in pure state is either blue
or white in colour gradually turns to pink upon absorbing
moisture in the air to saturation levels. In order to
ensure that the transformer functions properly, as a
routine maintenance procedure, the selica gel should be
changed as soon as it turns pink.

Answer / gambheer singh indauliya
breather is used in transformer to absorb the moisture
contain from the air pass going inward of x mer.breather
reduce the problem of short circuit in transformer.breather
provide economic and efficient terms for controlling level
of moisture. in the breather a silica gel is used to absorb
dust particles from air & oil.

Answer / abubakar bashir
breather is used to kept the oil when it becomes too hot and expands.it allow the oil to cool and return it to the transformer after cooling.

Answer / abhishek goyal
Breather connected to the conservator unit by pipe
arrangement (oil transformer). when load change or increase
(it produce more heat)and according to atmosphere
temperature oil will be change its position or level into
the tank so conservator (or tank)need air for space to
settable position of oil into the tank(expansion/
suppression). So that air flow come through the breather to
reduce atmosphere moisture for preventing form dielectric
strength (>40KV IE standards) of oil and unwanted fault.
