ISOLATION TRANSFORMER

Transformers are electromagnetic devices, which transform alternating current (AC) electrical energy from primary to secondary side. The energy is transformed with equal frequency and approximately equal power by means of the transformer core magnetic field. Thus they provide galvanic isolation in the electrical system. The isolation transformers operate in the same way as other transformer types. But the main task is to provide the galvanic isolation in the electrical system. They can work as step-up transformer or step-down transformers but often operate with turn’s ratio. This means that the primary and secondary voltage values are equal. This is obtained with a same number of turns on the primary and secondary windings. The isolation transformers are used in many electrical devices as computers, measurement devices or specific industry power electronic devices.  Any Double Wound Transformer is internally 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. An Ultra Isolation Transformer (UIT) ensures this, it provides for total electrical and electrostatic isolation with most effective screening of spikes, surges and transients, further it gives a true isolated local neutral and dedicated earth, which is 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 transformers action through mutual inductance. It prevents transfer of RF and HF disturbances with extensive insulation between primary and secondary.
