What is difference between a wet type and dry type transformer?
Transformer oil is a much better electrical insulator than air. So, in large transformers, oil is used to reduce the flashover distances between live internal parts, thus reducing the overall bulk of the transformer. At the same time, oil helps cool the transformer either by natural convection, or by forced circulation.'Dry transformers' are transformer that do not use oil for insulation or cooling purposes. They tend to be transformers with lower voltage and power ratings, where flashover and cooling is far less relevant.
What is AN on a transformer?
It is electronic device which pass or transform a electric energy from one ckt to anoher ckt The answer is wrong. AN denotes the cooling method of Transformer. AN means Air Natural

Where the transformer oil is circulated in the transformer and how it27s cooling the transformer?
Heat is one of the leading causes of transformer failure. The main source of heat generation in transformers are caused by copper loss in the windings and core (I²R losses). If this heat is not properly dissipated, the temperature of the transformer will rise continually which may cause damage to the insulation. A transformer operating at just 10°C above its rating will reduce its life by 50% so it is imperative to understand how transformers are cooled and how to detect problems in their cooling systems. ANSI and IEEE require the cooling class of each transformer to appear on its nameplate. The cooling classification of a transformer, expressed in letters, designate the type cooling system used. Transformers may have multiple load ratings that correspond to multiple stages of cooling.
Is phenyl-2propanone in trasformer cooling oil?
Phenyl-2propanone, also known as P2P, is not typically found in transformer cooling oil. Transformer cooling oil usually consists of mineral oil or synthetic fluids designed to provide proper insulation and heat transfer properties for the transformer. P2P is a organic compound that is not commonly used in transformer applications.
What is the function of a thermostat transformer in a heating and cooling system?
The function of a thermostat transformer in a heating and cooling system is to convert the standard voltage from the electrical system into a lower voltage that can be safely used by the thermostat to control the heating and cooling equipment.
