Are all isolation transformers immune to interference?

We commonly call isolation transformers safe isolation transformers, and often use them in medical equipment and mechanical precision equipment, which are very important for the safety of human electricity use. This is mainly because it can play the role of "isolation", "static shielding", anti-interference and so on. So, how does it play the role of anti-interference?


From the structural design of the isolation transformer, we found that: there will be a layer of insulating paint on the outer layer of its wire, the input and output lines are not common lines, and the middle will be separated by an insulating layer. The primary and secondary are isolated from each other, which leads to the isolation of the transformer loop. Therefore, when we pass the power grid into the isolation transformer, the disordered signals in the power grid enter the primary circuit of the isolation transformer, and cannot generate a magnetic field, and cannot couple with the secondary to form a loop, thereby playing a role in shielding interference.

The ground wire will be connected to the isolation transformer, which can effectively shield the high-frequency interference seen between the primary and secondary; it can also effectively shield the high-frequency interference from the power grid, and it can also effectively shield the high-frequency interference generated by the transformer due to the application circuit to the power grid, and at the same time it can reduce the cross-interference between multiple devices.


Therefore, we can know that the isolation transformer can have the function of shielding interference mainly due to its design structure and materials.


The isolation transformer structure of EEIO Transformer is composed of all copper wire + imported silicon steel sheet core + polyester film, mylar glue, copper foil and other insulating materials, which can effectively and efficiently protect the circuit and protect our human safety!
