An isolation transformer is a transformer used to transfer electrical power from a source of alternating current to some equipment or device while isolating the powered device from the power source, u
A 230 V isolation transformer
A simple 1:1 isolation transformer with an extra dielectric barrier and an electrostatic shield between primary and secondary. The grounded shield prevents capacitive coupling between primary and secondary windings.

Various types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, a

In an electric arc furnace, the transformer has a heavy copper bus for the low voltage winding, which can be rated for tens of thousands of amperes. Winding beginnings and ends are led out separately and "interleaved" for the external delta closure in a Knapsack connection. The transformers are immersed in oil for cooling and insulation, and are designed to withstand frequent short circuits.
