A bushing is a hollow insulator, used with Transformers and circuit breakers. It provides a means by which an energised conductor can pass from the outside to the inside of the transformer or circuit breaker.

What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
Where is the use of earth transformer?
It is used in where the transformer are connected in star delta.
What use of conservator tank in transformer?
To enable the oil in the transformer tank to expand and contract with temperature changes.
What does the power rating of a transformer imply?
Knowing the power rating of a transformer will help an operator use the transformer within its design limitations with regard to heating of the windings and their insulation.
Why is a transformer necessary?
A transformer is not 'necessary'. The human race evolved, and developed cultures, societies, disease resistance, and technology, without ever seeing a transformer. But there are specific situations in which desirable things can be accomplished much more effectively and efficiently with a transformer than with any other device or method. Here are a couple of examples: -- If the voltage you have available is not the voltage you need, then you can use a transformer to make the change. (But that only works for AC.) -- You can use a transformer to change the output impedance of an amplifier to the impedance of the speaker or earbuds you want to use with it.
What is use of metering core in transformer bushing?
It is the current transformer core meant for metering.
What is generator BCT?
BCT usually stands for bushing current transformer.
What does the terminology - radial feed - mean in relationship to transformers?
This terminology usually refers to pad mounted transformers. A "radial feed " transformer is a transformer that has one bushing for the high voltage cable line. The high voltage cable terminates into the transformer through the transformer's bushing. There is no second bushing for the high voltage cable to continue further down the line. This type of transformer is usually on the end of a loop feed circuit. This is different from a "loop feed" transformer whose incoming cables are terminated at the primary bushings. On this type of transformer there is a second bushing which connects to the outgoing primary voltage cables that allows the primary to feed another transformer. Each pad mount transformer's secondary feed usually supplies enough power to connect up to four homes.
What are the bushing in the current transformer?
The bushing acts as an insulator to prevent a short circuit. In large distribution transformers, the voltages used are so high that it the wires cannot be allowed to come too close to each other, or too close to the metal casing of the transformer. If they do get too close, then the voltage can actually jump through the air (electrical breakdown), and create a short circuit. The bushings are made longer than they need to be because things like rain, and sharp points on a transformer terminal can make it easier for the voltage to jump through the air.
What are high voltage bushings?

120v240v what does it mean?
In North America it is the standard electrical service connection voltages. Usually a pole mounted transformer supplies this voltage. In newer subdivisions the trend is turning to pad mount transformers which allows the primary voltage lines to be underground. Looking at the transformer you will see three insulator bushings. The first and third bushing are the working voltage (house connections 240 volts). The middle bushing is a center tap. This gives a voltage of (bushing left to center 120 volts) and (bushing center to bushing right 120 volts) These are the the three wires that come into a house for its 120/240 volt service.
What is the breakdown voltages of 100KVA transformer bushing and arcing horns?
The question isn't correct, you have to define the voltage level not the power rating.
What is a transformer protector?
The TRANSFORMER PROTECTOR is a transformerexplosion and fire prevention system suitable for any type of oil-immersed transformer and including surrounding equipment such as the On Load Tap Changer (OLTC), Oil Cable Box (OCB), and Oil Bushing Cable Box (OBCB).
What is the function of bushings in transformer?
Transformer Bushings are specially designed electrical terminals for taking out winding ends (leads) through the openings provided on the top cover or wall of the of transformer tank and connecting to the incoming and outgoing lines.cravi@gmail.com

Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
How many bushing do you get on delta to star transformer?
Your use of the word "bushings" implies you are dealing with a high-voltage transformer (over 600 volt). A three phase STEP-DOWN transformer normally has 3 bushings on the Primary side regardless of whether it is star-delta or another type. The Secondary side might have 3 or 4. A single phase transformer normally has 2 bushings on the Primary side and 2 or 3 on the Secondary side. If the transformer is being used to STEP-UP, it would be reversed from above. If this does not answer your question, I need more info.
