Isolation Transformer – Features & Advantages
Isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformer is usually used for the safety of equipments. It is transfer the AC electrical power from source to equipment while powered device is isolated from the source. Generally we can say that, any true transformer is working as per isolating transformer because primary and secondary coils are not connected with each other and they transfer power or signal by induction method but Isolation transformers are more specific, there primary task is to isolate circuits not just voltage conversion.

These transformers are used to protect sensitive devices such as computers from the electric shock and provide galvanic isolation. Electrostatic shields are used in Isolation transformers to provide continue power supply to sensitive equipments such as laboratory and testing equipments. They can transfer power between two devices, which are not connected.
Some transformers from A M Power are also used for the purpose of isolation as they have same input and output voltage both the side. Isolation transformers are also working effectively with the switching power supply as they can limit the harmonic signals from degrading the working performance of other devices. This phenomenon is extremely useful for the equipments which are containing microprocessors. This transformer can add additional weight, cost and sizing, its design also require more cooling but Isolation transformers can provide reliable solutions even when system has switching supplies.
