Projekat: Povećanje energetske efikasnosti, pouzdanosti i raspoloživosti elektrana EPS-a utvrđivanjem pogonskih dijagrama generatora i primenom novih metoda ispitivanja i daljinskog nadzora (MPNTR - 33024)
Sažetak
Izolacioni sistemi snažnijih obrtnih mašina se već dugi niz godina podrobnije ispituju metodama koje su konstantno unapređivane i potvrđene. Mašine manjih snaga i, uslovno rečeno, manjeg značaja, kao što su visokonaponski motori, su često održavani minimalnim sredstvima i neretko ne podležu ozbiljnijim električnim ispitivanjima. Uvođenjem EDA (Electronic Dielectric Analyzer) metodologije u praksu stvaraju se uslovi za pouzdanu i potpuniju dijagnostiku stanja statorskih namotaja velikih mašina, kao i brz, jednostavan i jeftin 'screening' velikog broja mašina manjih snaga kao što su visokonaponski motori. U radu će biti prikazana EDA metodologija i mogućnosti koje pruža, kao i mogućnosti softverskog i hardverskog rešenja.
Abstract
The insulation system of rotating machines of high importance has always been the object of thorough screening with certified test methods that are getting constantly improved. Low-power machines and 'less important' machines like high voltage motors, are rarely subjected to detailed electrical tests because of low resources allocated for their maintenance. The introduction of the EDA methodology in practice creates the conditions for reliable and complete diagnostics of stator windings of big machines, as well as the fast, easy and inexpensive screening for low-power machines (i.e. HV motors). The aim of the paper is to present the EDA methodology and its possibilities, including the solutions within the hardware and software.
