Variable
transformer is the device that has the output voltage varied from zeros to
maximum. Variable transformer transforms voltage with the help of magnetic
coupling that has null moving parts in it. The transformer consists of magnetic
core with the two or more couple that winding associated that will have the
incoming voltage. The transformers also make the important role for all the
electrical industry as it is more responsible for transferring the energy from
a single circuit to any other circuit with the magnetic core. The transformers
are divided in different types such as step up, step down, electric
transformer, variable auto transformer, current transformer, linear variable
transformer, high voltage, low voltage,
enclosed, distribution, isolated, core
and plugged transformers. Step up transformers are used for increasing the
voltage when the current is reduced. Step down transformer is useful for
overturning the winding relation.
Isolation
is divided into the primary and secondary circuit so that this break will not equalize
the direct current noise that occurs in the circuit. The transformer type will
also protect the circuit from any of the shock that is caused by high voltage
expulsion. Variable auto transformer is useful for changing the voltage for the
secondary circuit so that it can be useful for the low voltages as well as for
protecting the arching. The Variable
Transformers Motorized device has exceptional versatility as well as
reliability for the required voltage control applications plethora. When the
electric power is higher then it will make magnetic fields around it.
