Isolation transformers operate in the same manner as other transformer types. However, they are primarily used in electrical systems to provide galvanic isolation. They can be used as step-down or step-up transformers, but they usually have an identical turns ratio. This means that the primary voltage value is the same as the secondary voltage value. As a result, the number of turns on the primary obtained equals the number of secondary windings. Isolation transformers are used in a variety of electrical devices such as computers, measurement instruments, and specific industry power electronic devices.
