This is an advanced version of isolation transformer. Construction of ultra isolation transformers is very different from the regular isolation transformer.
In this secondary coils are split (or primary and secondary coils) as two or more coils according to the capacity of the transformer. The shielding method is also different because of the construction style. There is an inductance created between the coils because it is split. This inductance will give you more noise attenuation. As primary coil is not wound on top of the secondary coil the coupling capacitance is less. This is mainly required for wireless stations and costly life saving medical equipment.
Advantages Of Ultra Isolation Transformer:
1) High noise attenuation level even in the high frequency application.
2) Reduced coupling capacitance.
3) Core will not saturate even if the applied voltage is high.
4) Suitable for higher harmonic area installation.
5) Because of the lesser heat dissipation the life more...

Current Transformers
A current transformer (CT) is a type of instrument transformer designed to provide a current in its secondary winding proportional to the alternating current flowing in its primary. They are commonly used in metering and protective relaying in the electrical power industry where they facilitate the safe measurement of large currents, often in the presence of high voltages. The current transformer safely isolates measurement and control circuitry from the high voltages typically present on the circuit being measured.
Current transformers are used extensively for measuring current and monitoring the operation of the power grid. The CT is typically described by its current ratio from primary to secondary. Often, multiple CTs are installed as a "stack" for various uses (for example, protection devices and revenue metering may use separate CTs). Similarly potential transformers are used for measuring voltage and monitoring the operation of more...
