A New Line of Orthomagnetic Bushing-Type Current Transformers

The development of this new line of orthomagnetic bushing-type current transformers makes it possible to obtain the higher classes of metering accuracy, in the lower range of line current ratings, in high-voltage systems. At the same time it is possible to retain the advantage of minimum space, easy installation, dependable operation, and much of the economy of the usual bushing-type current transformer. The multiratio feature incorporated in the design of these transformers will materially facilitate their application on circuits where load conditions may change.
