Isolation Transformer 1000w shipped from Sydney

An isolation  transformer is a transformer, often with symmetrical windings, which is used  to decouple two circuits. An isolation transformer allows an AC signal or  power to be taken from one device and fed into another without electrically  connecting the two circuits. Isolation transformers block transmission of DC  signals from one circuit to the other, but allow AC signals to pass. They  also block interference caused by ground loops. Isolation transformers with  electrostatic shields are used for power supplies for sensitive equipment  such as computers or laboratory instruments.

Isolation  transformers are also used for the power supply of devices not on ground  potential as one option. 
Isolation transformers are commonly designed with careful attention to  capacitive coupling between the two windings. This is necessary because  excessive capacitance could also couple AC current from the primary to the  secondary. A grounded shield is commonly interposed between the primary and  the secondary. This greatly reduces the coupling of common-mode noise  present on supply conductors.

Differential  noise can magnetically couple from the primary to the secondary of an  isolation transformer. This requires other measures, such as a filter, to  block differential noise from the secondary of an isolation transformer.

Note: Tortech Isolation 240/240V transformers include a grounded shield  between the primary and the secondary windings as a standard accessory (E/S  Models). 

This screen  has a very high coupling to the input winding. Hence it will reduce the  common mode noise.
