An Isolation Transformer is one whose primary and secondary windings are separated from each other. It is made of two copper coils which are wound around each other and each supplied their own power source. In technical terms, it is a transformer, which is specially designed to isolate a circuit from an alternating current.
It completes its function by separating two circuits by reducing the alternating current’s voltage before it comes in touch with the circuit itself. It plays an important role in increasing the safety of your electronic system.Continue reading →

An Industrial Transformer is the most influential device that is used to transform electrical energy from one device to another with the help of mutual induction. For this purpose, you will not require a direct electrical connection between the two and the operation of mutual induction is carried between two windings of the device.
It is available in the huge range to serve the industries with the complete requirements. The range includes Control, Auto, Three Phase, Step Down, Step Up, Isolation, Rectifier, and Special Purpose Transformers among various others. Each variant has different working but all of them provide a constant supply of power at last.Continue reading →

A transformer is a tool commonly used to transfer electrical energy from a certain circuit to another circuit by means of inductively tied conductors. These conductors are made up of two or more ferromagnetic coils named as windings. When there are any electrical alterations made in the main winding, this creates a sporadic magnetic field in the core.
Thus, it will reproduce a fluctuation that includes the field on both sides of secondary winding. As a result, it provides intermittent electrical energy in the secondary coils. There are various forms of transformers that help transfer electrical power. One popular form is the isolation transformer, which offers different applications and purposes.Continue reading →

You may have heard lots about ferrite beads, but you may be wondering – how do ferrite beads work? Unfortunately, they are not the most straightforward to understand. If you need to use them, then you need to understand them thoroughly. For example, you must understand their electromagnetic characteristics as they can change while being used. Once you are knowledgeable about ferrite beads, one must be selected for the circuit board. If you don’t select the correct one, it will cause problems.Continue reading →
What is the purpose of RF coils?The purpose of RF coils (radio frequency coils) is that they can be a transmitter, a receiver, or both. They are used in magnetic resonance imaging (MRI).Continue reading →

In simple terms, the three-phase transformer is generally a combination of three windings. This type of transformer has a lot of offer due to it’s ability to supply large loads and power distributions. It is compact, easy to install, requires low maintenance, and is a highly durable device. There are four winding connections for three-phase transformers to ensure improved performance.Continue reading →
The Power Transformer
If you are considering investing in a power transformer, it’s crucial to know the devices as best as you can. For example, the differences between high voltage verses low voltage transformers. Transformers are quite complex and a crucial element of power transmission. Furthermore, the most appealing aspect is that it can last up to three decades.Continue reading →
Auto Transformer – What Is It?
It is a transformer that has just one winding, wound around a laminated core. It is a piece of equipment that supplies power from one circuit to another. This is carried out through electromagnetic induction. Auto transformers are similar to ordinary transformers regarding their functions and features. However, there is a difference in the interrelation between their primary and secondary windings. Auto transformer advantages and applications are plentiful.Continue reading →
