To evaluate the implementation of an electronic technique that increases the apparent magnetic core permeability in high-current, openable-core AC and AC/DC current transformers.
Applied an electronic permeability-enhancement method to openable-core current transformer architectures capable of measuring AC only, DC only, or simultaneous AC and DC.
Constructed and tested two hardware prototypes: a 5000 A/5 A openable-core AC transformer and a 2000 A/1 A openable-core AC/DC transformer.
AC current measurement accuracy reached approximately 10 p.p.m. across both prototype transformer designs.
DC current measurement accuracy achieved better than 100 p.p.m. in the openable-core AC/DC prototype.
