Rezumat: Luand in considerare faptul ca trecerea izolata este un element cheie in functionarea transformatorului electric de putere, functionarea sa in conditii de siguranta este o problema speciala, deoarece deteriorarea acesteia duce in multe cazuri la explozii urmate de incendii cu consecinte foarte grave pentru statii si substatii. Acest articol trece în revista toate avantajele de monitorizare on-line si prezinta un echipament numeric de monitorizare continua a starii trecerilor izolate reprezentand contributia proprie a autorilor

Cuvinte cheie: trecere izolata, condensator, izolator, transformator

Abstract: Because the bushing is a key element in the operation of electric power transformer, its safe operation is a special issue since its damage often leads to explosion followed by fires with very serious consequences for the stations and substations . This paper reviews all the advantages of the on-line monitoring and presents an equipment for on-line monitoring of bushings, which is the own contribution of the authors.
