Isolation transformers

Isolation transformers are specifically designed and manufactured to ensure load protection by means of galvanic separation between the mains and the user.
Typical fields of application are telecommunication systems, data centre supply systems, ‘trafoless’ UPSs supply, bypass lines protection, public buildings and hospitals.
An isolation transformer is always fitted with an electrostatic shield between primary and secondary windings for noise attenuation and discharge to ground of voltage surge.
Windings are built in delta/star or delta/zigzag configuration (with available neutral point) in order to cancel the third and triplen harmonics.
