摘要：
A high-voltage current transformer has an external inductance element electrically connected thereto. The inductance element has a relatively low magnitude of inductance, compared with the inductance of the current transformer, to cause a substantial increase in the excitation current which significantly reduces the residual flux in the current transformer.
