Transformers are versatile electrical equipment used to transfer electrical energy between two or more circuits. A varying current in one coil produces a varying magnetic flux, which induces a varying electromotive force across the second coil wound around the same core. Thus, with the help of a transformer, electrical energy can be transferred between the two coils, without having a metallic connection between the circuits. Transformers have found their usage in all kinds of industries like industrial, commercial, aerospace, medical, electronics, audio, and more. In fact, they are also used in domestic and residential applications. All in all, transformers are a vital part of almost every electric and electronic appliance. Transformers have thus made our lives very easy and simple.
Isolation transformers, like every other kind of transformer, is used to transfer electric power from an alternating current power source to a device, with the difference being that in this case, the powered-up device will be isolated from the power source for safety reasons. With this setup, not only is the device kept safe, but the operators assigned to handle and manage the operations are also protected against possible accidents and hazards. The main principle on which isolation transformers work is isolating the various sections of electrical systems in order to halt the flow of current, with no direct path of conduction. However, energy is still exchanged between various sections via electromagnetic waves, induction, or capacitance. All in all, isolation transformers keep blocking DC signal transmission from one circuit to another, while allowing AC components to pass by.
Transformers are static electrical devices that transfer AC electric power from one circuit to another at a constant frequency, while increasing or decreasing the voltage, as required by the equipment. The process that helps such transfer is electromagnetic induction.
Electrical transformers are always heard to be making humming and buzzing sounds, which can be very frustrating and disturbing. The reason for this noise is the process of magnetostriction that goes on within the transformer, in which a magnetic steel sheet changes it dimensions and shape when magnetized. Because magnetostriction is an important process of a transformer, the noise cannot be completely eliminated. But yes, if desired, it can be reduced to a certain extent.
Almost everything that we use today is automated and works on power. The things that we depend on everyday – smartphones, laptops, televisions, refrigerators, microwave ovens, lights, fans, air conditioners, geysers – all require power to run. Without these appliances, life is almost impossible; and without power, the working of these appliances is impossible. Thus, power transfer is very important for us today. Let alone these everyday appliances, even the systems in medical facilities are now automated and require power. Every big and small appliance in hospitals and clinics works on power supplied to them. Thus, without power, we would not be able to even get the best medical facilities that we have access to today!
As much as transformers are important to us in our daily lives, by providing us with safe amounts of current and electricity to run our electric and electronic appliances, they can be equally hazardous if not used properly. This is why it is important to undertake certain safety measures while operating your transformers, or during its regular maintenance or repair procedures. Any carelessness may lead to shocks, or even death. In addition, it may lead to errors, which even if minute, may damage the entire transformer, which may further result in failure of the appliance too. You definitely don’t want any of this to happen, which is why you need to take up these safety measures for sure.
Inductors are passive two-terminal electrical components that store energy in a magnetic field, when electric current flows through them. They generally consist of an insulated wire wound into a coil, around a core. Common mode chokes work as passive electronic inductors that filter out frequencies. High frequencies are specifically eliminated, while allowing low frequencies in an electronic system. With such properties, they have proven to be really helpful when used in electrical transformers.
As much as PCB manufacturing is important, equally crucial is testing the PCB. Testing ensures that the product is safe and good to go in every aspect. However, every PCB assembly manufacturer from India has its own different way of testing the product. There are a number of testing procedures available that one can choose from, to analyze the working condition of the components. Let us tell you the most popular ones that are proven and tested across the globe.
There are a number of PCB manufacturers out there, each providing their own unique services, and boasting about their benefits. To choose from that list, it is important that you know what a PCB manufacturer is, what he does, and what he is responsible for. This knowledge will help you differentiate between the good and ineffective ones, so that you can make the best decision for your particular PCB requirements.
Electrical transformers are used to transfer electrical signals from one circuit to another with fluctuating voltage levels and no frequency alteration. They can increase as well as decrease the alternating voltages in electrical power applications. They work on the principle of electromagnetic induction, where a coil of wire magnetically induces a voltage in another coil located close to it. Transformers can step up or step down the voltage and current levels of their supply, as required by the application. Used in both residential and industrial applications, they are used to distribute power across long distances.
