Transformers Cores: A New Genre Of Advancement In The Electrical World


Transformers are electronic devices used in various electrical systems to transfer electric energy, precisely alternating current (AC), by reducing or increasing it into one or more circuits. It works on the principles of electromagnetic induction and is widely used for voltage management.

A transformer is one of the primary devices used in a wide range of electrical systems. From reducing the voltage for electric-sensitive devices like toy trains and doorbells to increasing the voltage for heavy machines like generators that require continuous current for extended periods, the uses of transformers are limitless.

But the real hero behind all these valuable transformers functions is its Core. From production to electromagnetic effect, these cores are the reason a transformer transmits the power in the form of Alternating Current from one source to another.

Want to know more? Transmart (the industry leader of transformer cores) explains an elucidated guide on transformer cores, how they work, and their importance. So, make sure you thoroughly read it till the end.


Transformer Cores: Leading An Eco-friendly Environment


The central primary piece of the transformer is called the Core, and the transformer's functionality solely depends on it. Working as magnetic circuits, the Core provides a pathway for the magnetic field to flow around the transformer, the base of the transformers' workflow.

Silicon steel lamination is the favorite choice of transformer core manufacturers as they have strong capabilities of carrying the magnetic flux produced for induction. But, they might be made of materials like iron, amorphous metals, ferrite ceramics, and many others.

A transformer core contains two winding, primary and secondary. Primary winding refers to the terminal connected to the source from where the transformer receives the current.

In comparison, secondary winding refers to the part that supplies the current from the transformer to the other machine, device, or system.


Generally, the transformers' core manufacturing depends upon the placement of the primary and secondary winding of the wires. Based on structure, the core construction is of two following types:


● Closed Core construction

● Shell type construction


Let's dig a little deeper into them one by one.


Closed Core Construction:


In this type of transformer core construction, the primary and secondary windings are placed outside the ring. They surround the core ring and comparatively have a higher risk of flux leakage.  


Shell Type Construction:


In this type of transformer core construction, the primary and secondary winding are placed inside the steel magnetic circuit. The core ring will form a covering around the winding and overcomes the risk of flux leakage.


Essential Characteristics Of A Transformer Core: What To Expect Additionally?


Silicon ferrite lamination with strong magnetic permeability to handle the magnetic flux effectively has much more than increasing and decreasing the voltages. So, keep reading and know the essential features to expect in your transformer cores.


● Transformers Can Be Noisy:


The loud sound made by the transformers is produced when the current flows from the primary coil to the secondary coil, interacting with the magnetic effects and affecting the iron core.


The transformer's Core starts to contract and relax continuously due to magnetic effects, resulting in an irritating, loud humming sound. But it can be controlled to a greater extent by tightening the bolts, using oils, and mounting the transformers on rigid straight surfaces.


● Transformers Working Can Cause High Heat Production:


Like other electronic devices, transformers, regardless of the devices they are working in, produce a high heat content as a byproduct.


 And this heat raises the temperature of the transformer core and the whole electric system, which eventually affects the efficiency ratio.


Therefore, discuss the actual load and no load losses in watts with your magnetic core manufacturers before getting a transformer for your machines.  


● Regular Maintenance After Every 6 Months:


Transformers require regular maintenance sessions after six months to ensure the functionality of the internal components as well as working efficiency.


From checking the rust on the silicon iron strips to measuring the heat production, maintenance and repair are critical for worthy results for the money you're paid.


Toroidal Transformer Core: An Exceptional Addition To Transformer's Industry

A specialized toroidal transformer has more efficiency than normal ones. It has a toroidal transformer core that is a rounded shape with a hollow center, around which the primary and secondary coils are wounded.

Similar to standard transformers, the toroidal transformer cores are made of silicon steel strips that are melted and rolled to form a toroidal shape.

While in the case of working, the functionality process is the same: induction through a primary coil, EMF effect on the secondary coil, transfer of current from primary to the secondary coil, and then supply to the circuit through the secondary coil.
