Isolation transformer is used to transfer electrical power from A.C.to some equipment and protect against electric shock and to suppress electrical noise in sensitive devices. For the safety reason, isolation of powered device from the power source is done. In isolation transformer insulation is provided between primary and secondary windings to withstand a high voltage between windings.
An isolation transformer is mainly used for the safety and protection purpose of electronic components and the persons against electrical shock. Galvanic isolation is provided by the energy transformed with equal frequency and equal power by means of the transformer core magnetic field. Isolation transformer can be used as step up or step down transformer. Primary and secondary voltage and number of turns on primary and secondary windings are same.
