What is an isolation transformer?
     An isolation transformer is a type of transformer that is used to isolate electrical circuits from one another. It is designed to have two separate and isolated windings, with no electrical connection between the primary and secondary sides. The primary winding is connected to the source of electricity, while the secondary winding is connected to the load.



What is the purpose of an isolation transformer?
     The purpose of an isolation transformer is to provide electrical isolation between the primary and secondary sides of the transformer. This is useful in a variety of applications, including protecting sensitive electronic equipment from voltage spikes and other electrical disturbances, and preventing electrical interference between two circuits.

     The turns ratio of an isolation transformer is the ratio of the number of turns of wire on the primary winding to the number of turns on the secondary winding. The turns ratio determines the voltage transformation ratio of the transformer, and is typically expressed as a ratio or a percentage. For example, a transformer with a turns ratio of 1:1 has the same number of turns on the primary and secondary windings, and does not change the voltage of the electrical current. A transformer with a turns ratio of 1:2 has twice as many turns on the secondary winding as on the primary winding, and will step up the voltage by a factor of 2.

Where is the isolation transformer used in power systems?
     Isolation transformers are used in a variety of applications in power systems, including in power distribution systems, medical and laboratory equipment, and industrial processes. They are also used in electronic circuits and devices to provide electrical isolation and protect against voltage spikes.
