breather will be connected in conservator...when ever there
is an expansion or contraction takes place in transformer
oil due to temp. changes conservator will take or remove
air through breather....in breather silica gel will be
there...this is used to remove moisture

Answer / sunil guru

Answer / raul

breather is basically to absorb d moisture content in atmospheric air entering d transformer which can deteriorate d oil properties i.e. insulating properties n can cause acidity n sludge formation in the tranformer oil. so when ever the transformer oil cools there is a contraction of oil in d transformer tank which draws atmospheric air into the conservator through a breather which is a cylindrical tank containing silica gel crystals impregnated wid cobalt chloride which r initially blue in colour n when dey absorb d moisture d colour turns into pink. when 1/3rd of the crystals appears pink, flushing of the complete charge is done n fresh crystals r introduced into d breather............
