Any Double Wound Transformer is inherently an ISOLATION TRANSFORMER as the primary and secondary are isolated from one another through insulation. However, modern machines and systems need a truly isolated, clean and stable power requirement. This is ensured by an Ultra Isolation Transformer (UIT). It provides for total electrical and electro static isolation with most effective screening of spikes, surges and transients. Further, it gives a true isolated local neutral and dedicated earth which are very essential for modern machines.
Ultra Isolation Transformer attenuates common mode noise and transverse mode noise and provides for noise or interference free power. In principle, UIT only transfers 50 Hz power by transformer action through mutual inductance. It prevents transfer of RF and HF disturbances with extensive insulation between primary and secondary. The insulation levels withstands HV breakdown strength of 2.5 KV and gives a DC galvanic isolation of above 1000 mega ohms.
