Premier Current Transformer Manufacturing Company

As a premier leader among current transformer suppliers, Midwest Current Transformer has served customers requiring high quality current transformer products for more than five decades. Our targeted focus is the manufacture of standard and custom design current transformer solutions to meet the requirements of a wide range of applications.

Customized Current Transformer Design

We offer pre-made current transformers to serve the needs of various power applications. Our team is able to customize your order in order to help you achieve the optimum current transformer solution in terms of size, ratio, accuracy, multiple taps, contacts, mounting options, and burden rating. Our range of transformers includes: instrument current transformer, multi ratio current transformer, toroidal current transformer, donut type current transformer, current metering transformer and more.

Our Electrical Current Transformer Construction

At Midwest Current Transformer, we manufacture the majority of our current transformers from cold-rolled grain oriented electrical steel (CRGO). The CRGO steel comprising our current transformers is rolled into your required inner and outer diameter dimensions which permits precise dimensioning and tight construction between layers. As an iron-silicon alloy, CRGO electrical steel provides high permeability and low core loss that enables greater efficiency and cost-effectiveness of the current transformer.

Total Quality Management

Our approach consists of Total Quality Management protocol in which our employees, customers, and suppliers are valued as an integral part of our successful process. Our standard for success is error-free performance with the commitment to error prevention and getting-the-job-done-right-the-first-time mindset.

Through hands-on product inspection as part of an entire quality management system, we strive for perfection at every stage of the manufacturing process before your products leave our hands. We push toward continual quality improvement, adherence to safety standards, and personnel development through high-value training across all levels of our operations.

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.
