Osborne’s Auxiliary Current Transformers
Osborne Auxiliary Current Transformers are often used to reduce system currents to lower values appropriate for instrumentation and/or protection circuits. The Aux CT’s are designed for specific current ratios and burden impedance with a known transformation error. Osborne’s units are built for high performance and longevity in the most demanding environments.
Let’s talk about your project.

Why Osborne Transformer?
Every Osborne transformer is designed for extreme durability. Your design begins with extensive electromagnetic and mechanical modeling, then proceeds through a detailed battery of simulations. These simulations are progressively optimized to arrive at the ideal core, conductor, and other critical components. Your application will engage the expertise of a select network of the world’s finest raw material suppliers. The composite parts of your transformer will be built in strict compliance with Osborne’s exacting standards, and rigorous testing procedures.
