Such type of CT is also known as CBCT (Core Balance Current Transformer). Each winding offers different turn ratio providing access to two different current ratings on each individual windings. This is a dual core current transformer that has two cores each with individual secondary winding. The double core of the transformer increases the rating of the transformer.ĭual Core Current Transformer with Two Secondary Lines There is a single conductor (primary) going though both of the cores of the transformer. Such type of current transformer has two cores. The current produced in its secondary is proportional to the current in its primary (conductor) & it is measured by connecting it with a conventional Ammeter. ![]() Such type of transformers is used for current control in welding applications.Ĭurrent transformer is a type of instrument transformer used for decreasing high alternating current in a line down to safe levels for measurement purposes. ![]() Such type of transformer has an adjustable core which increases or decreases the flux linkage between the windings to increase or decrease the current flow.
