New Product Series: CST25 Current Sense Transformers

The engineers at Triad are always working to offer cutting-edge magnetics solutions that provide clients with the highest, most efficient performance possible. In keeping with this commitment to constant improvement and innovation, the team is pleased to announce the launch of our new line of current sense transformers — the CST25 series. 


Exploring Current Sense Transformers

Commonly employed in high-current circuits, current sense transformers (CSTs) are a type of instrument transformer used to measure current values in a conductor.

In current transformers (CTs), the primary has very few windings and is connected in series with the conductor carrying the current to be measured. The secondary contains a number of windings that are wound around a secondary ferromagnetic core. Current transformers are sometimes referred to as “series transformers” because the primary winding — which always has very few turns — is in series with the current-carrying conductor supplying the load.
