When Can You Reverse Connect a Transformer?

Engineer looking at computer infront of transformer - When can you reverse connect a transformer? In this article, we zero in on your questions about transformers. Today, we answer whether or not you can (or should) reverse connect a transformer.

The Verdict on Reverse Connecting Transformers

Reverse feeding a transformer is not a recommended practice, as it can lead to decreased performance and potential damage. However, some distribution transformers can be reverse-connected without reducing their nameplate KVA capacity. It is important to take precautions when reversing the connection of smaller transformers, such as three-phase transformers under 6kVA and single-phase transformers under 3kVA. These smaller transformers have compensative turns to ensure accurate/clean voltage. For larger transformers, reverse connecting can cause increased in-rush currents leading to nuisance tripping or damage. VCM’s rental transformers are designed & manufactured for bi-directional energy flow to keep your power flowing, whatever the voltage, or direction.

Use a Step-Up Transformer Instead

For optimal performance and safety, it is best to use a step-up transformer instead of reverse-connecting a transformer. Step-up transformers increase the voltage output of a system, allowing for efficient energy transfer. They are designed for safe and efficient operation, making them a better choice for most applications.
