What is KNAN cooling?

Can you increase the efficiency of transformer by increasing the cooling of transformer?

nope


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.


Which type of oil is used in transformer for cooling the windings?

Mineral oil


What are the causes of overheating of distribution transformer?

poor cooling mechanisms, and overloading.


What is odaf cooling in a transformer?

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 .


What are the methods of cooling transformer in table form?

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


What is an explanation of the cooling of transformer?

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


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 the function of radiator in power and distribution transformer?

Radiators are used in a transformer to cool the transformer oil through natural air or forced air flowing in these radiator fins. As the transformer oil temperature goes down due to cooling it goes to the transformer tank from bottom ,cool the windings and gets heated, and then returns to the radiator for next cooling .This cycle repeats as the oil flow is also natural due difference in temperature of oil on bottom and top. In big power transformers this oil circulation is forced by oil pumps for effective cooling. The radiator has many small fins and there are 4-10 radiator banks in a transformer depending on capacity and make of the transformer.


Standard transformer cooling methods?

Standard transformer cooling methods include; Air cooling and oil cooling.AnswerTransmission and distribution transformers are oil filled. Cooling is achieved either by natural convection yo the sides of the tank (small distribution transformers) or through cooling tubes, or by pumped circulation through external heat exchangers. The heat exchangers themselves, are cooled by natural convection, forced air draught, or water.


What type of cooling is used in dry atmospheres in transformer?

forced air and draft oil dissipate
