Abstract

Procedeul de control al starii avariate a liniei de transport, conform inventiei, consta în deconectarea, la ambele capete, a fazei avariate a liniei, compresarea capacitatilor fazice si interfazice ale liniei pentru suprimarea curentului de arc, compararea valorii semnalului electric pe faza deconectata a liniei ce apare ce urmare a tensiunii induse de la cele doua faze conectate cu valoarea semnalului corespunzator tensiunii aplicate pe faza deconectata neavariata si aprecierea starii fazei deconectate, în functie de rezultatul compararii, dupa un timp prestabilit de la deconectarea fazei de avarie, determinat aproximativ de timpul de ardere a arcului, se micsoreaza compensarea capacitatilor interfazice ale liniei, cel putin la unul din capetele ei, de valoarea initiala la zero, iar compararea semnalului electric corespunzator tensiunii induse este faza deconectata neavariata, se efectueaza în intervalul de timp necesar pentru controlul rigiditatii dielectrice a fazei deconectate.
