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.
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.
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.
If you need to use transformers on an intermittent basis then hiring is going to be the most flexible and practical solution. It allows you to be able to choose the best transformer for your equipment and change as necessary. At HSS, we have variety of transformers available for hire with different ratings to suit your needs. Get in touch with our online live chat team who are on hand and happy to help or contact your local store.
Please note - Transformers with a kVA rating of 5 or above will need to be hardwired by a qualified electrician.
