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.

…interrupt power, but generate a warning. Isolation transformers are also used for the power supply of devices not at ground potential. An example is the Austin transformer for the power supply of air-traffic obstacle warning lamps on radio antenna masts. Without the isolation transformer, the lighting circuits on the mast…
Austin ring transformer at the base of a WMCA and WNYC transmitting tower in Kearny, New Jersey. The two interlocking rings are the primary and secondary transformer windings. The spherical objects directly below and to the right of the windings are a spark ball gap, for lightning protection.
