Isolation Transformer

Isolation transformers work in a similar manner as conventional dry-type transformers. However, instead of containing just the primary and secondary windings, an isolation transformer also contains electromagnetic (EMT) shield at the transformer’s core to help protect the equipments that the transformer is connected to. The shield works by preventing any high frequency noise or signals, from the primary side, from being induced into the secondary winding and any sensitive equipments that may be connected to the systems.


Estel’s isolation transformers are designed and tested according to IEC61558-2-6:2009 or as specified by customers.
