what are the parts of power transformer?

A power transformer consists of several key components: the core, which provides a magnetic path; primary and secondary windings, which are coils of wire that facilitate energy transfer; insulation materials, which separate the windings and core; tap changers, which adjust voltage levels; and a tank or enclosure, which houses the transformer and contains insulating oil for cooling and insulation. These parts work together to efficiently transfer electrical energy between different voltage levels.
