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.
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 leakage current in transformer?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
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 the use of shunt in power transformer?
In Power Transformer in higher rating to minimise the Stray losses (losses caused by leakage flux linking with structural part- tank - yoke plates) Tank shunts shunt the leakage flux and contains it within. shunts are made of CRNGO.

How can stop transformer oil leakage?
Find the leak and repair it. There's not much else to say!
What is magnetic leakage of a single phase transformer?
The magnetic leakage should be very small and designers go to some lengths to reduce it as far as possible because it causes leakage inductance, which is a bad thing. Ideally the magnetic field must be confined to the magnetic core of the transformer.
Does leakage flux produced in one winding cut into another winding in a transformer?
No.that's why it is considered as a drawback

What do you mean by leakage reactance in a single phase transformer?
The leakage reactance is one of the components of the reactance in the input impedance that is there when the load impedance is purely resistive. The leakage reactance is due to flux that fails to link both the primary and the secondary windings.
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
What is pressure test for transformmer and how to test?
On installed transformer a test is performed to check weather it has any oil leakage or not, the test is called pressure test, more precisely pressure leakage test.
