Gassing of insulating liquids under electrical stress and ionization

Describes two procedures each using different apparatus to measure the tendency of insulating liquids to evolve or absorb gas when subjected to electrical stress.

Das Gasen von Isolierflüssigkeiten unter elektrischer Beanspruchung und Ionisation

Gassing des isolants liquides sous contrainte électrique et ionisation

Décrit deux méthodes, utilisant chacune des appareillages différents pour évaluer la tendance des isolants liquides à émettre ou absorber des gaz lorsqu'ils sont soumis à une contrainte électrique.

INTERNATIONAL ELECTROTECHNICAL COMMISSION
GASSING OF INSULATING LIQUIDS
UNDER ELECTRICAL STRESS AND IONIZATION
FOREWORD
I) The formal decisions or agreements of the I E C on technical matters, prepared by Technical Committees on which all
the National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
3) In order to promote international unification, the I E C expresses the wish that all National Committees should adopt
the text of the I E C recommendation for their national rules in so far as national conditions will permit. Any divergence
between the I E C recommendation and the corresponding national rules should, as far as possible, be clearly indicated
in the latter.
PREFACE
