George Westinghouse invented it in 1885.
Henry Orenstein invented transformers.
Alternating Current
the heat formed in the core due to the "eddy currents" burns a transformer
George Westinghouse invented the air brake for electric railway cars around the 1880's. He also purchased the patent rights to generators which used alternating currents, as well as patenting transformers that reduced high-voltage power to lower voltage levels. His new system made long-distance transmission more efficient, over Edison's system of direct current which couldn't transmit electricity very far.
In the "War of Currents", George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current for electric power distribution over alternating current advocated by Westinghouse and Nikola Tesla. AC was and it is the best system.
A current transformer is used for measurement of alternating electric currents. Current transformers, together with voltage transformers are known as instrument transformers.

You cannot connect transformers of different voltage in parallel. This is because circulating currents will be set up between the two transformers that may exceed their rated currents.
AC generators, powerplants etc produce alternating currents.
Eddy currents

Yes he did. In 1885 George Westinghouse, head of the Westinghouse Electric Company, bought the patent rights to Tesla's system of dynamos, transformers and motors. Westinghouse used Tesla's alternating current system to light the World's Columbian Exposition of 1893 in Chicago.
