Title:
TRANSFORMER FOR MEASURING INSTRUMENT
Document Type and Number:
Japanese Patent JPS58191410
Kind Code:
A
Abstract:
The current transformer for instruments for measuring electric currents includes a magnetic core that has two cores and an inductive current divider with three parallel current paths. The current dividers form, together with cores, two current transformer stages whose magnetic fluxes mutually cancel one another. In a current transformer for AC currents having a DC component, the ratio of the ohmic resistances of the individual current paths is in direct relation to their transformation ratio.
