If anybody have seen the transformer carefully then you
must notice that breather is installed at the vent pipe
connected to the Oil tank & the open end of the vent pipe
in tank is on top.
In any kind of fault condition , if the heat is produced &
Oil gets expand then it will increase the volume of oil in
tank & excessive oil will be get drain through the way of
vent pipe , but in the healthy condition only are passed
through the vent pipe & obvisiosy air definately contain
the part of Moisture & as the moisuture is the one of the
enimy of electrical sustem , it needs to be prevent while
enrering in to the transformer . for that breather is
arranged the dry silica gel is put in to breather & once
the air passes thorogh breather as per silica property it
will absorb the moisture & change its own colour to the
pink,. once it shows the pink colour immediately open the
breather . remove the silica & apply heat for some period
of time & again you can re use it.
result shows that moisure can reduce the dielectrica
strengh of oil.
the good quality oil can sustain its property up to 50 KV &
the oil with some oil gave away at 18 kv.
