Grease is not used in Transformers. An insulation oil is used to circulate around the internal coils to dissipate the heat generated when the transformer is in operation. Thermo syphon principals are used. Warm oil moves to the top of the transformer case and is displaced by cooler oil moving to the bottom creating a flow in the oil and there by aiding in the cooling of the coils. Transformers in larger sizes have cooling fins or tubes through which the oil flows to give more surface area to dissipate the internal coil heat. Smaller size transformers use the oil contact with the oil containment shell of the transformer to dissipate the heat.

What is the need of frequency in electrical power?
Transformers are used in AC circuits and won't work for DC. A frequency of 60Hz is popular in the USA.
What are at least 2 types of electrical transformers in science?
A variety of electrical transformers are produced for a variety of purposes. All of the types use the same principle discovered by Michael Faraday, and employ many of the same parts. The various types include. Audio transformers, Instrument transformers, Pulse transformers, Power transformers, RF transformers. .
How do transformers reduce electrical voltage?
This type of transformer is called a Step-Down transformer. All transformers have an input to output ratio. The transformers that increase voltage are called Step-up, and the transformers that protect against surges are called unity gain. The Unity gain transformer has a 1:1 ratio and provide a mechanical way to isolate a source of voltage from a load.
What does N1 mean in electrical transformers?
Represents the number of coil turns on the primary side of the transformer.
Which type of electrical power-related tranformer steps up the voltage to several hundred thousand volts in order to reduce energy losses?
Step-up transformers of the type you describe are three-phase transformers which, in the transmission system, are classified as 'power transformers'.
What is tie transformer?
It is a step down transformer which is used to supply the electrical power to the station transformers and the colony transformers
Where are transforers used?
Most electrical transformers are used to step up or step down the voltage of alternating electrical current.
What is electrical grease?
dielectric grease.
Electrical Properties of Transformers why you use it?
Transformers are used to convert electricity from high voltage to low voltage and from low voltage to high voltage.
Is platinum used in transformers?
my father is best friends with an electrical contractor and he said that there is indeed platinum cores in electrical transformers i dont know how much but he said its alot of money and therefore is not supposed to be public knowledge.
What film is better transformers or terminator?
avitar, grease, titanic
What is Dielectric grease used for?
It's supposed to be non-conductive yet it transfers heat. Dielectric grease is often used with a heat-sink to transfer the heat better and it can also be used in applications where electrical components might get damp and/or hot and corrode. Most auto manufacturers are using dielectric grease or other grease compounds to protect light sockets and other electrical connections.
Can chuck Norris poop transformers?
No. Nobody can defecate transformers, whether you mean electrical transformers or the cartoon series.
What small building contains transformers and electrical equipment?
a substation go to http://www.chacha.com/question/what-are-small-buildings-containing-Transformers-and-electrical-equipment is where i found the anser
What are Square D transformers?
Square D is a brand of electrical components. In an electrical application, you might see Square D transformers, or perhaps General Electric, or another brand.
What is the need of frequency in electrical power?
Transformers are used in AC circuits and won't work for DC. A frequency of 60Hz is popular in the USA.
Why is it important to use the correct fire fighting equipment for Electrical and Non electrical fires?
Water conducts electricity and is therefore contraindicated for use on energized electrical equipment, however it is much cheaper than the chemicals that can be used on energized equipment making it more economical when water is able to be used. Similarly water should not be used on grease fires as it will spread out the grease and the fire rather than smothering it.
