Modifications in transformer design to reduce temperature rise

An ideal transformer is one which has no losses. This would entail having purely inductive coils wound on a loss-less core, impossible to realize in practice. Transformer losses are dissipated as heat, leading to higher operating temperatures which cause the transformer insulating materials to deter...
