CASE STUDY: A COMPARATIVE ANALYSIS OF THE ELECTRIC FIELD NEAR LOW FREQUENCY ELECTRIC LINES

Autor/autori: Eng. Florin Daniel IRIMIA PhD Student, Eng. Mihai ANDRUSCAPhD Student

Rezumat: Aceasta lucrarea analizeaza monitorizarea si diagnosticarea cu ajutorul campului electric pentru o linie electrica de joasa frecventa, in diferite regimuri de functionare (normal sau de defect) cu ajutorul a trei metode diferite: prima presupune modelarea utilizand programul EMTP, iar a doua si a treia metoda presupun determinari directe in situ a campului electric. A doua metoda se bazeaza pe masurarea directa a campului electric cu un dispozitiv patentat de autori. Ultima metoda utilizeaza un dispozitiv special (METRAHIT) pentru masurarea directa a campului electric. Rezultatele obtinute sunt comparate.

Abstract: This paper analyzes the monitoring and diagnosing using the electric field for one low frequency line, for different operating status (normal and short circuit) using three different methods: the first one is modeling using EMTP program and the second and third methods are for directing measuring in situ of the electrical field.The second method is based on a device patented by the author. The last one uses dedicating tool (METRAHIT).The obtained results are comparing.
