Abstract
The sheath circulating current of some high-voltage cable exceeds standard, and the circulation suppressor can alleviate this problem to some extent. However, if ground fault happens, the short-circuit current will flow through the circulation suppressor, resulting in over voltage. Therefore, a circulation suppression method for short-circuit current guidance was proposed. The influence of impedance angle, installation phase and impedance ratio of suppressor on the suppression method were analyzed, and the results showed that the circulation suppression method of short-circuit current guidance had the characteristics of circulation suppression, fault current guidance and high safety.
