Mineral oil-filled electrical equipment - Application of dissolved gas analysis (DGA) to factory tests on electrical equipment

This International Standard specifies oil-sampling procedures, analysis requirements and procedures, and recommends sensitivity, repeatability and accuracy criteria for the application of dissolved gas analysis (DGA) to factory testing of new power transformers, reactors and instrument transformers filled with mineral insulating oil when DGA testing has been specified. The most effective and useful application of DGA techniques to factory testing is during the performance of long-term tests, typically temperature-rise (heat run) and overloading tests on power transformers and reactors, also impulse tests on instrument transformers. DGA may also be valuable for over-excitation tests run over an extended period of time. Experience with DGA results, before and after short-time dielectric tests, indicates that DGA is normally less sensitive than electrical and acoustic methods for detecting partial discharges. However, DGA will indicate when these partial discharges become harmful to the insulation and may be detected by inspection.

Impregnirani izolacijski materiali - Uporaba analize raztopljenih plinov pri tovarniškem preskušanju električne opreme

Ta mednarodni standard določa postopke za vzorčenje olj ter zahteve in postopke za analizo ter priporoča merila za občutljivost, ponovljivost in natančnost pri uporabi analize raztopljenih plinov (DGA) za tovarniško preskušanje novih impregniranih izolacijskih močnostnih transformatorjev, reaktorjev in instrumentnih transformatorjev, kadar je bilo določeno preskušanje z analizo raztopljenih plinov. Tehnike analize raztopljenih plinov so za tovarniško preskušanje najučinkovitejše in najuporabnejše, kadar se uporabijo za dolgotrajne preskuse, običajno za preskuse močnostnih transformatorjev in reaktorjev s segrevanjem in preobremenitvijo ter sunkovne preskuse instrumentnih transformatorjev. Analiza raztopljenih plinov je lahko pomembna tudi pri preskusih s pretiranim vzbujanjem, ki se izvajajo v daljšem časovnem obdobju. Izkušnje z rezultati analize raztopljenih plinov pred kratkoročnimi dielektričnimi preskusi in po njih kažejo, da je zaznavanje pri analizi raztopljenih plinov običajno slabše kot pri električnih in akustičnih metodah za zaznavanje delnih razelektritev. Vendar analiza raztopljenih plinov kaže, kdaj lahko te delne razelektritve poškodujejo izolacijo, zaznati pa jih je mogoče s pregledom 2.
