A Guide to Transformer Hire

Updated - October 9th 2023

The purpose of a transformer is to change the voltage of electricity flowing in a circuit. Transformers can be used to both increase and decrease voltage. Increasing voltage is called stepping up and decreasing voltage is called stepping down. Transformer hire can be difficult to understand at first and when working with high voltages it is important to know what you’re doing in order to keep safe.

How Does a Transformer Work?

A transformer consists of two or more coils of insulated wire wound around a steel core. One coil contains the primary current and the other is the secondary. When voltage is introduced to the primary coil it magnetizes the core and then enters the secondary coil. Voltage can be changed based on how many times the primary and secondary coils has more turns.

Stepping Up

A step up transformer is able to boost a low voltage to a higher one. When there are more turns in the secondary coil than in the primary, this makes a step-up transformer and ensures the voltage is higher in the secondary coil.

Stepping Down

If the primary coil has more turns than the secondary, then it's a step-down transformer. The purpose of a step down transformer is to decrease voltage by increasing the electrical current.
