A method and system for compensating the electromotive forces of self-induction and mutual induction in a conventional asymmetric high current line

摘要

The method involves applying an additional voltage forced by line currents of the magnitude$\mathop{\mathrm{image}}$ to each line phase in series close to the supply trans­former.;It is sufficient to refer the phase current derivatives to the basic harmonic of that current.;The system consists of three transformers (Tr), the primary sides whereof being series-connected to the indi­vidual phases (F₁, F₂, F₃) of the high-current line and the secondary sides whereof being series-interconnected by means of three four-poles (C₁₂, C₁₃, C₂₃), prefer­ably of the Γ type, an isolating transformer (Ts) being placed between any two four-poles.
