What is a Transformer Core?

A transformer is an electrical device designed to convert alternating current from one voltage to another. It can be designed to increase or decrease voltages. The most commonly known example of electrical transformer usage is to convert the energy created at the power plant to a useable voltage by the time it gets to your home so you can safely use your appliances.

Inside every transformer lives a core that does the heavy lifting. It consists, in its simplest form, of two or more coils of insulated wire wound on a laminated steel core. When a fluctuating electric current flows through the primary wire, it generates a magnetic field that creates electricity in the secondary wire. Power can be regulated by changing the number of coils and dimensions of the steel core.

Transformer cores are all around us! Not far away, there’s a transformer station hidden away converting energy to power your neighborhood. Every time you flip your light switch or turn on your TV, you are utilizing the magic of electrical transformer cores!
