Sažetak

U radu je prikazan sistem za merenje i automatsku regulaciju protoka gasa koji je deo uređaja za ispitivanje oksidacione stabilnosti transformatorskih ulja 'Termoblok'. Uz već ranije realizovani uređaj za monitoring i automatsku regulaciju temperature uzoraka ulja realizovan je model protokomera koji je ujedno i automatski regulator protoka vazduha ili kiseonika kroz uzorke ulja. Posebna specifičnost realizovanog sistema je merenje veoma malih protoka gasa. Dat je kratak tehnički opis realizovanog sistema sa funkcionalnim blok dijagramom. Specificirane su osnovne tehničke karakteristike sistema, koncept rada i primena ovakvog sistema. U radu su priloženi i rezultati sprovedenih ispitivanja na realizovanom sistemu u realnim uslovima eksploatacije.
