Current transformers | Choosing the Right Transformer
There are 5 main types of transformers. The differences between each transformer are related to the types of applications possible. Current transformers: these are transformers in which the secondary current is proportional to the primary current. They can be used with all low-frequency alternating currents. Power transformers: these are distribution transformers with a voltage of one phase higher than 1,000V. They are used to transport electricity over long...
