Systems and methods for implementing line overload control via providing distributed series impedance are disclosed. One system, amongst others, comprises at least one distributed series reactor (DSR). Each DSR comprises a single turn transformer (SST) comprising two split-core sections (132), a winding (120), and an air-gap (138), the air-gap designed such that a magnetizing inductance is produced when the two split-core sections (132) ar e clamped around a conductor (108). Each DSR further comprises a contact switc h (122) that short circuits the winding when the contact switch (122) is in a closed condition, a power supply (128) that derives power from conductor lin e current, and a controller (130) configured to open the contact switch when t he conductor line current reaches a predetermined value, thus causing insertion of the magnetizing inductance into the conductor. The controller (130) may b e further configured to close the contact switch (122) when the conductor line current drops below the predetermined value.
