Understanding How Transformers Work


Before you even think about using a transformer calculator, your first question is probably; why don’t power stations simply transmit electricity at the expected voltage? Why is there a new for high voltages. To explain that, it pays off to know more about how electricity travels. Fret not since we are here to help clear some of the doubts in your mind.

As electricity flows down a metal wire, the electrons carrying its energy jiggle through the metal structure, bashing and crashing about, and generally wasting energy. No wonder wires get host when electricity flows through them. Actually, the higher the voltage electricity you use, and the lower the current, the less energy is wasted in this way.

Going back to our discussion topic, how does a transformer work? Well, a transformer is based on a very simple fact about electricity. When a fluctuating electric current flows through a wire, it generates a magnetic field all around it. The strength of the magnetism is directly related to the size of the current. In short, the bigger the current, the stronger the magnetic field.

Keep in mind a transformer’s main function is to step-up or step-down the voltage from the primary to the secondary windings.  This is made possible through adjusting the ration of coils on one side to the other. If your transformer has 5 coils on the primary and 10 on the secondary for instance, it will be a 1:2 step-up transformer.

What this simply means is that the voltage doubles from the primary to the secondary. But if it has 10 coils on the primary, and 5 on the secondary, it would be a 2:1 step-down transformer. This cuts the voltage in half.

It takes time before you finally understand how an electric transformer works. But that’s not to say you can never take advantage of what a transformer calculator can do. As long as you do a bit of research, rest in knowing you can never go wrong with the calculations. So, what is preventing you from leveraging what a transformer calculator offers?
