Method of sampling insulating liquids

This document is applicable to the sampling procedure used for insulating liquids in delivery containers and in electrical equipment such as power and instrument transformers, reactors, bushings, oil-filled cables, oil-filled tank-type capacitors, switchgear and load tap changers (LTCs). This document applies to liquids the viscosity of which at the sampling temperature is less than 1 500 mm2/s (or cSt). It applies to mineral oils and non-mineral oils (such as synthetic esters, natural esters, vegetable oils or silicones).

Verfahren zur Probennahme von Isolierflüssigkeiten

Méthode d'échantillonnage des liquides isolants

L'IEC 60475:2022 s’applique à la procédure d'échantillonnage utilisée pour les liquides isolants dans les récipients de livraison et les matériels électriques tels que les transformateurs de puissance et de mesure, les réactances, les traversées, les câbles à huile fluide, les condensateurs de puissance en huile, les appareillages de connexion et les changeurs de prises en charge (LTC - load tap changer). Le présent document s'applique aux liquides dont la viscosité, à la température d’échantillonnage, est inférieure à 1 500 mm2/s (ou cSt). Il concerne les huiles minérales et non minérales (les esters synthétiques, les esters naturels ou les huiles végétales et les liquides silicones, par exemple).

Metoda vzorčenja izolacijskih tekočin

Ta dokument se uporablja za postopek vzorčenja za izolacijske tekočine v transportnih vsebnikih in električni opremi, kot so močnostni in instrumentni transformatorji, dušilke, skoznjiki, oljni tlačni kabli, oljni kondenzatorji za nihajni krog, stikalne naprave in bremenski odcepni preklopniki (LTC).
Ta dokument se uporablja za tekočine z viskoznostjo, ki je pri temperaturi vzorčenja manjša od 1500 mm2/s (ali cSt). Uporablja se za mineralna in nemineralna olja (kot so sintetični estri, naravni estri, rastlinska olja ali silikoni).
