Your question is incomplete -- what about the transformer?

?

Are you asking about a transformer turn to turn fault? Or if a transformer is shorted, does this turn into a fault? Please clarify the question.

VA or KVA or MVA

Answer:

Transformer name plate shows the rating of the transformer...viz., operating frequency, rated current n voltage, output power in KVA, type of insulation used, tranformation turns ratio...

Additional Info: in addition to that, you would also find the percent impedance, size of the tank, tap configuration, and vector group. Here is photo of a typical power transformer nameplate: http://www.jcmiras.net/jcm2/p20.htm

No transformers only work with AC.

yes there is left left up left right down right

A: Absolutely a power transfer will have an internal loss of IR . for a power transformer the loss can be as much of 20% or more if other magnetics are involved like iron screw holding the lamination together. Usually brass is used to reduce that loss.

Copper is typically preferred over aluminium for transformer coils due to its higher electrical conductivity and better heat resistance, leading to improved efficiency and reliability. While aluminium is cheaper and lighter than copper, it has higher resistance and can result in higher losses and lower efficiency in transformers.

Most computer power supplies contain both. The transformers are usually toroidal transformers for high efficiency and compactness.

well if that's true for you then i think maybe you should see a therapest........

keep in mind that theres no shame in therapy.

200 and 100

To convert DC (battery) to AC to run household appliances you need an "inverter". Because they are usually hooked up to a car battery (12V) they can't provide too much power. Usually enough to run lights, a small refrigerator, TV or laptop computer OR similar low power equipment.

If you mean how they work then magnetic fields

Induction. Voltage applied to one winding induces a voltage in another winding. The voltage induced is dependent upon the turns ratio between the two windings.

Current is said to be induced in the other winding as well (since a voltage is induced, current will flow if the circuit is complete). Depending on the transformer type, current may flow directly from the series winding (in autotransformers, for example) to the secondary output (conduction, as opposed to induction).

You're assuming that the line is dead shorted. In that case, assuming zero source impedance, current would increase as well. In reality, source impedance often limits the very high voltage short circuit current to less than the lower voltage.

Think of it this way: I have a 120 volt, 5000 watt totally resistive load (no motors). At 120 volts, I am pulling 41.67Amps. Say the power plant supplying this load is 100 miles away, and the overhead power line (regardless of voltage level) has .01 ohms/mile resistance (total of 1 ohm resistance). If the power company tries to deliver power at 120 volts, instead of the 5000 watts I want, I will get 5000 watts, but the power company will have to generate (5000 + 1 * 41.67^2) = 6736 watts*.

If instead the power company steps the voltage up to say 13.8kV right outside my house (as close to the load as possible), total current at 13.8kV will be 362mA, so total power loss in transmission is .131watts (as opposed to 1736 at 120 volts).

From the 120 volt perspective, my 5000 watt load "looks like" 2.88 ohms, since P = V*I = V^2/R.

If we are looking at my house through a 13.8kV/120v transformer, the transformer has a turns ratio of 13800/120 = 115, thus increases voltage by 115 times, and decreases current by 115 times (from lowside to highside). Thus from the 13.8kV perspective, my 5000 watt load "looks like":

P = V^2/R = (120 * turns_ratio)^2/R = (120*115)^2/R = 13800^2/R

R = 38,088 ohms.

The transformer changes voltage and current inversely to each other; this results in a change in apparent impedance relative to the highside and lowside of the transformer.

*This is assuming the power company is delivering voltage at 120 volts through the line, and uses some sort of reactive power to compensate for the voltage drop through the line. This is often done by installing capacitor banks, or having generators closer to the load produce reactive power. The wasted transmission losses plus the cost of this extra equipment would result in higher power costs being passed on to customers.

a hole transformer

Transformer has windings

yes we can place auto transformer in place of original transformer

The function of fans in a transformer is to regulate the transformer's temperature.

A transformer that increases voltage is a step-up transformer.

Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.

An isolation transformer is usually a ferromagnetic transformer.

The question needs to be framed more usefully.

because the copper is saved in the auto transformer

that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio

A transformer does many things.

The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.

there is nothing like a balanced and unbalanced transformer.

Ideal transformer is useful in understanding the practical transformer..i does't have losses...

This type of a transformer is known as a step up transformer.

The function of the radiator ban in a transformer is to cool the transformer oil.

why should we use pulse transformer rather than ordinary transformer

Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.

Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.

A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.

B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.

It is a transformer with No load attach to it.

Frgi transformer

auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy

ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer

Berry transformer has good ventilation provision as compared to other types of transformer

CT=========current transformer

PT=========potential transformer

these are the instrumental transformers.

Both are same. This is an instrument transformer used for metering & protections.

The 3 kVA transformer will weigh double the 1.5 kVA transformer.
