Answer / pundlik wanwe
Transformer properties are governed by the 2 Indian
Standards.1) IS 335 & 2)IS :1866
IS 335 is for new oil
IS 1866 is for oil in service
For the transformer in service as long as oil in
transformer is ok as per IS 1866 there is no requirment as
such for filteration of oil, but you have to follow the
manufactuer's instructions regarding this

Answer / geno peter
well , if the BDV is found ok, then not required to filter
the oil

Answer / ramjeet singh
Yes; at least once in a year it should be filtered and
tested as per IS 1866-2000 to withstand not only BDV,
moisture but all the 9 test parameters; as at least we
should know what has happened in terms of oil
characteristics within a year.

How impulse levels are calculated that for 11kV impulse is 75kvp, for 24kV impulse is 125kvp ?
we have two 11/.433 kv. distribution Transformer rating as 1000 kva & 500 kva , i wants to run parallel both transformer. both transformer impendence voltage is 5.24%, How can we run both t/f, & how sharing the load
