Most Transformers have a name tag, start there. If it's outside, theres a 75% chance it's filled with oil. Generally oil filled transformers are housed in a cylindrical powder coated steel container, green, grey or tan. Ranging in size of pole mount(Keg), pad mounted (Car), to Substation transformers(size of your house) Larger Oil filled transformers have cooling capability, large radiator looking thing on the side with one to many electric fans blowing air past the cooling fins.
Liquid immersed transformers are typically immersed in what?
The predominate liquid used inside a filament transformer is mercury. Mercury is used to keep the transformer cool when under heavy use. Mercury is a cheap and long lasting liquid.
Condensation
To identify transformer winding shortage. If there is shortage between winding turns magnetic current test is the best to identify. Shaukt from Abudhabi.UAE
A transformer's 'nameplate' lists all the data necessary to identify the rating, connections, etc., of a transformer. Part of this data is the 'vector group' information which applies to three-phase transformers, and which, in simple terms, tells us whether or not the transformer can be connected in parallel with another.
Without knowing the type of transformer (audio/power, step-up, step-down, etc.) it's difficult to offer any advice.
An Amorphous solid
I believe that it means that your analysis of your data enables you to absolutely identify your unknown liquid as that specific liquid and no other liquid.
The Magnetic Balance test is conducted on Transformers to identify inter turn faults and magnetic imbalance.
It is used to detect and identify the presence of liquid chemical agents.
salt is a solid but water is a liquid
