What Is An Isolation Transformer

Isolation transformer refers to the input winding and output winding with galvanically isolated transformer, isolation transformer to avoid accidental simultaneous contact with the live body, transformer isolation is to isolate the original secondary side winding coil respective current. In the early days, it was used in the power industry in European countries, and was widely used in the control power supply, safety lighting and indicator light power supply of general circuits in the electronics industry or industrial and mining enterprises, machine tools and mechanical equipment.

A special transformer with high dielectric strength between the primary and secondary windings to isolate different potentials and suppress common-mode interference. The transformation ratio of isolation transformers is usually 1:1.
