There are many situations where we need to change the voltage of the electricity we are working with. Whether we need to turn the voltage up or down over long or short distances, we use step-up and step-down transformers to accomplish this. How do these transformers work, and how can they help you in your event, project, or facility?
Why Do We Use Step-Up and Step-Down Transformers?
Before we explain how they work, it will be useful for you to know why we might use step up or down transformers. The most common reason we use these is to transfer electricity over long distances. Power plants cannot always be conveniently located near consumers of electricity. So, the electricity must be sent from a power plant to the end consumer.
However, when it is sent over long distances, electricity drops in voltage. In order to counter this effect, we must increase its voltage before the journey. We use step-up transformers to increase the voltage; then we transfer the electricity. Now, before the electricity can be used by homes, factories and other consumers, it must be brought back down to the correct voltage. We use step-down transformers of distribution transformers for this purpose.
How Do Step-Up and Step-Down Transformers Work?
Transformers are made of two or more coils of wire wrapped around an iron core. You can imagine this as two iron posts with wires wrapped around both posts. When we run electricity through the first pole, it induces a new voltage in the second pole. The exact voltage you end up with depends on how many times the wires are wrapped around the two poles.
When you think of a step-up transformer, you could think of a machine that makes cheese strings. It takes separate pieces of cheese and winds it together to make a thicker piece of cheese. Step down transformers, then unwind the cheese string, making them the exact thickness (in this metaphor, that’s voltage) that you need.
What Voltage Do I Need?
You can use a step-up or step-down transformer to change the voltage you receive into the voltage you need for your event, factory, or another project. You may need expert help to determine what voltage you need and which step-up or step-down transformer you’ll need. It will depend on the kind of equipment you want to run and what kind of voltage they need. Large facilities may need two or more voltages delivered.
