Oil-filled electrical equipment - Sampling of free gases and analysis of free and dissolved gases in mineral oils and other insulating liquids - Guidance
IEC 60567:2023 deals with the techniques for sampling free gases from gas-collecting relays from power transformers. Three methods of sampling free gases are described. The techniques for sampling oil from oil-filled equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors are no longer covered by this document, but are instead described in IEC 60475:2022, 4.2. Before analysing the gases dissolved in oil, they are first extracted from the oil. Three basic methods are described, one using extraction by vacuum (Toepler and partial degassing), another by displacement of the dissolved gases by bubbling the carrier gas through the oil sample (stripping) and the last one by partition of gases between the oil sample and a small volume of the carrier gas (headspace). The gases are analysed quantitatively after extraction by gas chromatography; a method of analysis is described. Free gases from gas-collecting relays are analysed without preliminary treatment.

L'IEC 60567:2023 traite des techniques d'échantillonnage de gaz libres au niveau des relais de protection des transformateurs de puissance. Trois méthodes d'échantillonnage des gaz libres sont décrites. Les techniques d'échantillonnage de l'huile dans les matériels immergés dans l'huile, tels que les transformateurs de puissance et de mesure, les bobines d'inductances, les traversées de transformateurs, les câbles à huile fluide et les condensateurs de puissance ne sont plus couverts par le présent document, mais se trouvent dorénavant dans l'IEC 60475:2022, 4.2. Avant d'analyser les gaz dissous dans l'huile, ils sont en premier lieu extraits de l'huile. Trois méthodes de base sont décrites, l'une utilisant l'extraction sous vide (Toepler et dégazage partiel), une autre par déplacement des gaz dissous par barbotage d'un gaz vecteur dans l'échantillon d'huile (entraînement) et la dernière par partition des gaz entre l'échantillon d'huile et un faible volume du gaz vecteur (espace de tête). Après extraction, l'analyse quantitative des gaz s'effectue par chromatographie en phase gazeuse; une méthode d'analyse est décrite. Les gaz libres prélevés au niveau des relais de protection sont analysés sans traitement préalable.
Z oljem polnjena električna oprema - Vzorčenje prostih plinov in analiziranje prostih in raztopljenih plinov - Napotek
Standard IEC 60567:2023 obravnava tehnike za vzorčenje prostih plinov iz plinskih relejev močnostnih transformatorjev. Opisane so tri metode za vzorčenje prostih plinov. Ta dokument ne zajema tehnik za vzorčenje olja iz opreme, polnjene z oljem, kot so močnostni in instrumentni transformatorji, reaktorji, uvodnice, oljni tlačni kabli in oljni kondenzatorji za nihajni krog; te tehnike so opisane v točki 4.2 standarda IEC 60475:2022. V olju raztopljeni plini se pred analizo ekstrahirajo iz olja. Opisane so tri osnovne metode, prva z ekstrakcijo v vakuumu (Toeplerjeva črpalka in delno razplinjevanje), druga z nadomeščanjem raztopljenih plinov z vpihavanjem nosilnega plina v vzorce olja (odparevanje) in tretja z ločitvijo plinov med vzorcem olja in majhno količino nosilnega plina (plinska faza). Po ekstrakciji s plinsko kromatografijo se plini kvantitativno analizirajo; opisana je analizna metoda. Prosti plini iz plinskih relejev se analizirajo brez predhodne obdelave.
