Instrument current transformers (CTs) measure AC currents.The DC component in the measured current can saturate the transformer and cause gross Headphones error.We use fluxgate detection and digital feedback compensation of the DC flux to suppress the overall error to 0.15%.This concept can be used not only for high-end CTs with a nanocrystalline core, but it also works for low-cost CTs with FeSi cores.

The method described here allows simultaneous measurements of Vitamin B12 the DC current component.
