Oil-filled electrical equipment - Sampling of gases and of oil for analysis of free and dissolved gases - Guidance

Deals with the techniques for sampling free gases from gas-collecting relays and for sampling oil from oil-filled equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors. Three methods of sampling free gases and three methods of sampling oil are described; the choice between the methods often depends on the apparatus available and on the quantity of oil needed for analysis. Before analysing the gases dissolved in oil, they must first be 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 (head space). 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. The preferred method for assuring the performance of the gas extraction and analysis equipment, considered together as a single system, is to degas samples of oil prepared in the laboratory and containing known concentrations of gases (gas-in-oil standards) and quantitatively analyse the gases extracted. Two methods of preparing gas-in-oil standards are described. For daily calibration checks of the chromatograph, it is convenient to use a standard gas mixture containing a suitable known amount of each of the gas components to be in a similar ratio to the commons ratios of the gases extracted from transformer oils. The techniques described take account, on the one hand, of the problems peculiar to analyses associated with acceptance testing in the factory, where gas contents of oil are generally very low and, on the other hand, of the problems imposed by monitoring equipment in the field, where transport of samples may be by un-pre

Matériels électriques immergés - Echantillonnage de gaz et d'huile pour analyse des gaz libres et dissous - Lignes directrices

Traite des techniques d'échantillonnage de gaz libres apparus aux relais de protection et d'échantillonnage d'huile dans les matériels immergés dans l'huile, tels que les transformateurs de puissance, les réducteurs de mesure, les réactances, les traversées, les câbles à huile fluide et les condensateurs de puissance. Trois méthodes de prélèvement des gaz libres sont décrites, ainsi que trois méthodes de prélèvement de l'huile. Le choix entre ces différentes méthodes dépend souvent de l'équipement disponible et de la quantité d'huile nécessaire pour l'analyse. Avant d'analyser les gaz dissous dans l'huile, il faut en premier lieu les extraire 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 du 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 se fait par chromatographie en phase gazeuse; une méthode d'analyse est décrite. Les gaz libres apparus aux relais de protection sont analysés sans traitement préalable. La méthode préférentielle pour garantir le fonctionnement des matériels d'extraction des gaz et d'analyse, matériels considérés dans leur totalité, consiste à extraire les gaz d'échantillons d'huile préparés au laboratoire et contenant des concentrations en gaz connues (étalons de gaz dissous dans l'huile) qui seront analysés quantitativement. Deux méthodes sont décrites pour l'obtention d'étalons de gaz dissous dans l'huile. Lors de vérifications quotidiennes de l'étalonnage du chromatographe, il est commode d'utiliser un mélange de gaz étalons renfermant des teneurs en gaz connues et appropriées de chacun des composants gazeux devant être dans un rapport similaire aux gaz extraits des huiles des transformateurs. Les techniques décrites tiennent compte, d'une part, d

This European Standard was approved by CENELEC on 2005-09-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,

Foreword
The text of document 10/621/FDIS, future edition 3 of IEC 60567, prepared by IEC TC 10, Fluids for
electrotechnical applications, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60567 on 2005-09-01.
This European Standard supersedes EN 60567:1992.
The main changes with respect to EN 60567:1992 are listed below.
Since the publication of EN 60567:1992, a number of new gas extraction methods have been
developed and are commercially available, such as mercury-free versions of the standard Toepler and
partial degassing methods, which are referenced to in Annex C of this new edition. The head space
method, based on a new concept for the extraction of gases from oil is introduced as a full method,
and reference is made to a simplified version of it also in Annex C (shake test method). More sensitive
chromatographic techniques have also been developed and are presented in this new edition of the
standard.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-09-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 60567:2005 was approved by CENELEC as a European
Standard without any modification.
