Generally speaking, equivalent circuits are used to simplify a complex circuit into terms that are solvable with known relations. For example, in a transformer equivalent circuit you can account for winding losses and flux leakage with a series resistance and reactance on the primary side. Core losses can be modeled similarly with a parallel resistance and reactance on the primary also.
Essentially when reflecting/referring an impedance to the primary side of a transformer, you are just seeing what the secondary impedance "looks like" to the primary side. Since the secondary impedance will determine the load on the primary, it is helpful to know how to relate it in terms of the primary so as to calculate the current flow in the primary due to the load on the secondary.

What is the purpose of conducting sc and oc test of single phase transformer?
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.
What are the applications of equivalent circuit of a single phase transformer?
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.

What Is a core-core type 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.
