Answer / rajat sahu

(i)dielectric breakdown:-when hightemp high load occour
this water can boil and cause vapour bubble that result
dielectric failure.when temp cool this dissolved water will
separete from oil and cause fluid degradation.
(ii)corrosion.
(iii)loose clamping.

Answer / sheikh

in a huge amount of transformer oil one drop of water is
negligible. but a certain quantity of water Die electric
strength may be poor and creating short circuit or any other problem.
in 11kv system die electric strength level should be 40kv
as per standard.

Answer / vama

nothing will hapen. go ahead

Answer / mallu byali

It is loss the efficiency of transformer and may chance to
break down failure while loading (in loading oil temp will
get rise then water is going to separate from oil as well
as it will vaporized and affect the tx ventilation)

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.
