Constant Voltage Transformer vs Ultra-Isolation Transformer

Chennai city is leading in the hardware industry. From the past few years, it has advanced alot in hardware technology development. Foremost Nantech Power Systems Pvt Ltd., one of the most important major hardware manufacturing companies that provide top-level transformers.

Constant voltage transformer: -

Constant Voltage Transformer (CVT)is a non-linear transformer also known as Ferro resonant Transformer (Ferro).

Ferro resonance is a regulated voltage output provided by CVT through an electromagnetic phenomenon.

CVTs are basically 1:1 transformer that is excited high on their saturation curves, thereby providing an output voltage which isn’t significantly tormented by input voltage variations. This special characteristic is that the foundation of the appliance of Ferro resonant transformers as power conditioners.

Ultra-Isolation Transformer: -

An Ultra isolation transformer is a transformer that’s accustomed transfer electricpower from a source of alternating current (AC) power to some equipment or device while completely isolating the connected device from the power source, usually for safety.

An isolation transformer is a transformer, usually with symmetrical windings, which is used to decouple two circuits. An isolation transformer allows an alternating current(AC) signal or powers to be taken from one device and lead into another without electrically connecting the two circuits. Isolation transformers block the transmission of direct current (DC) signals from one circuit to another, but allow AC signals to pass through. They also block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment like computers, Lab Instruments, CNC Machines, Medical Equipments, etc.

Isolation Transformer employs a novel multiple shielding technique that reduces the inter-winding capacitance to a large extent and increases the DC isolation.
