Isolation transformers are designed to do one thing: isolate electricity. An isolation transformer works by separating the source of the electricity from the device the electricity is supplied to by distributing electricity to the device. Unlike most other transformers that change the voltage of electricity, isolation transformers are used to prevent unwanted electricity from escaping while still controlling the electricity transmitted.
Isolating the electricity is essential for many electronic devices, such as electric shavers, hair dryers,...
