Why leakage reactance is kept small?
Leakage reactance is useful for limiting the short circuit current in transformer and generators. therefore normally the reactance of transformer varies for 4.5% for distribution transformer to 12.5% for 400KV class.
What is the difference between ideal transformer and practical transformer?
There are basically 4 major differences :- 1. The windings (both primary and secondary) of an ideal transformer are considered to have zero resistance, hence the transformer is lossless. 2. There is no leakage flux in an ideal transformer. 3. The permiability of the core material in ideal transformer is considered to be tending to infinity and hence the current needed to set up the flux in the transformer is negligible. 4. There is zero hysterisis and eddy current losses in an ideal transformer.
What is transformer oil soak pit?
it is a pit which is used to drain leakage oil of transformers .AnswerIt's a walled area, surrounding a transformer, intended to contain any oil leakage from a transformer.
What are the advantages of shell type transformers?
this type of transformer used special low loss steel to minimize eddy current losses and reduced leakage flux.
How does an earth leakage transformer work?
What is the definition of earthing and how it works?

What is the Transformer about?
leakage rfactance
What is the source of energy loss in a transformer?
Heat. On less well designed (or incorrectly used) Transformers you can get current leakage too.

What is the source of leakage current in a transistor?
The current of the minority charges (collector region) is the source of the leakage current. At higher temperature, this leakage current increases due to increase in thermal energy.
Which current is the leakage current that flows through a photo diode with no input in a light detector?
leakage current itself
Why is leakage flux modelled in a transformerequivalent circuit as an inductor?
In a transformer equivalent circuit, leakage flux is modeled as an inductor because it represents the magnetic flux that does not link the primary and secondary windings effectively. This leakage affects the impedance and efficiency of the transformer, as it causes voltage drops and reduces the coupling between the coils. By modeling it as an inductor, we can accurately account for the reactance due to the leakage flux, which impacts the transformer's performance under load conditions.
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
