The Steps To Choosing The Right Current Transformer

There are many different factors to keep in mind when choosing a current transformer for any application. As this can be confusing and there is a lot of information out there that is not accurate, and this can lead to installing the wrong current transformer and having to replace equipment.

To make sure this does not happen, the first step is to contact the current transformer manufacturer if you have any questions or doubts about compatibility. The team at Midwest Current Transformer is here to answer your questions and to ensure that you are using the right product. Talking to our team when ordering current transformers allows you to have the right equipment for the job to avoid any last minute decisions and possible confusion.

Type of System

With any type of meter or power system, it is important to choose a current transformer that is designed for that system. This is particularly important with meters, as not all are uniformly designed. Another way to put this is that the metering or the protection required by the system is matched with the type of current transformer.

It is also important to know the primary range of the current transformer and to make sure this is compatible with the application. The various configurations of the primary and secondary windings provide this type of compatibility.

Accuracy Required

For current transformers that are used for measurement purposes, the degree of accuracy is essential. Not all current transformers offer high accuracy, and the more specific the requirement is, the more important the quality of the data measurement offered through the CT.

This accuracy rating is rated by class, with the current having an impact on the accuracy offered by the current transformer. For protective transformers, the same importance on the ability of the current transformer to perform to the required levels is always a factor in making the right choice.
