a transformer can be cooled by using forced air-essencially attaching fans to help pull heat away.

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.
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.
Transformer engineering is its' own specialty. If you want a deep explanation, I suggest you peruse some books on transformer engineering - I like the one with said name by Kulkarni and Khaparde (not great english, but understandable).
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.
It was introduced to expand the voltage in an electric circuit.
poor cooling mechanisms, and overloading.
Mineral oil
Oil Directed Air Forced , it's speical way to cooling transformers through predetermined pathes in transformer windings . this way provids fester rate of heat transfer .
1. By using transformer oils.2. By nitrogen or sulfur hexaflouride gases.3. By using flourinated hydrocarbons4. Case is wide corrugated5. Case is provided with radiators
Each letter in KNAN transformer cooling stands for something different. K indicates a beyond 300-degree Celsius flash point, N denotes natural, and A is equal to air.
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.
