what is the function of transformer in the half wave rectifier circuit
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
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.
there will be no neutral point in the circuit and high voltage will be across the transformer coils
These two tests are performed on a transformer to determine (i) equivalent circuit of transformer(ii)voltage regulation of transformer(iii) efficiency of transformer. The power required for theseOpen Circuit test and Short Circuit test on transformeris equal to the power loss occurring in the transformer.
Excitation current Io = Iw + Iu
The purpose of conducting sc (short circuit) and oc (open circuit) tests on a single-phase transformer is to determine its equivalent circuit parameters, such as the winding resistance, leakage reactance, and magnetizing reactance. These tests help to evaluate the transformer's performance and efficiency under various operating conditions.
Equivalent circuits allow you to treat the transformer itself as being 'ideal', while treating its losses, etc., as external elements to which the normal laws of networks apply.
Without knowing what they is, nobody will ever be able to answer your question.

With a transformer...
A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.

why does have to short-circuit secondary wire of current transformer ?
A transformer is used to transfer electricity from one circuit to another.
