In 1885, three Hungarian Engineers Otto Blathy, Miksha Deri, Karoly Zipernowsky invented the first ZBD Model (From the first letter of their second names) alternating current transformer. The Austro-hungarian Empire used these transformers for both experimental and commercial purposes. The principle of electromagnetic induction was discovered and
later developed by William Stanley, which is one of the major milestones of 19th century that saw the life cycle of transformers getting transformed beyond what is imagined then. Today
the industry has passed on through a number of revolutions and up gradations in the process of generating power. The role of transformers have been always outstanding!
