Oil-filled electrical equipment - Sampling of free gases and analysis of free and dissolved gases - Guidance
EN IEC 60567:2024

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.

Mineral oil-filled electrical equipment in service - Guidance on the interpretation of dissolved and free gases analysis
EN IEC 60599:2022

This document describes how the concentrations of dissolved gases or free gases can be
interpreted to diagnose the condition of oil-filled electrical equipment in service and suggest
future action.
This document is applicable to electrical equipment filled with mineral insulating oil and
insulated with cellulosic paper or pressboard-based solid insulation. Information about specific
types of equipment such as transformers (power, instrument, industrial, railways, distribution),
reactors, bushings, switchgear and oil-filled cables is given only as an indication in the
application notes.
This document can be applied, but only with caution, to other liquid-solid insulating systems.
In any case, the indications obtained are given only as guidance with resulting action
undertaken only with proper engineering judgment.

SIST EN IEC 60296:2020(Main)
Fluids for electrotechnical applications - Mineral insulating oils for electrical equipment
EN IEC 60296:2020

This document provides specifications and test methods for unused and recycled mineral
insulating oils (see Clause 3 for definitions). It applies to mineral oil delivered according to the
contractual agreement, intended for use in transformers, switchgear and similar electrical
equipment in which oil is required for insulation and heat transfer. Both unused oil and
recycled oil under the scope of this document have not been used in, nor been in contact with
electrical equipment or other equipment not required for manufacture, storage or transport.
Unused oils are obtained by refining, modifying and/or blending of petroleum products and
other hydrocarbons from virgin feedstock.
Recycled oils are produced from oils previously used as mineral insulating oils in electrical
equipment that have been subjected to re-refining or reclaiming (regeneration) by processes
employed offsite. Such oils will have originally been supplied in compliance with a recognized
unused mineral insulating oil specification. This document does not differentiate between the
methods used to recycle mineral insulating oil. Oils treated on-site (see IEC 60422) are not
within the scope of this document.
Oils with and without additives are both within the scope of this document.
This document does not apply to mineral insulating oils used as impregnating medium in
cables or capacitors.

SIST EN IEC 61125:2018(Main)
Insulating liquids - Test methods for oxidation stability - Test method for evaluating the oxidation stability of insulating liquids in the delivered state
EN IEC 61125:2018

This document describes a test method for evaluating the oxidation stability of insulating
liquids in the delivered state under accelerated conditions regardless of whether or not
antioxidant additives are present. The duration of the test can be different depending on the
insulating liquid type and is defined in the corresponding standards (e.g. in IEC 60296,
IEC 61099, IEC 62770). The method can be used for measuring the induction period, the test
being continued until the volatile acidity significantly exceeds 0,10 mg KOH/g in the case of
mineral oils. This value can be significantly higher in the case of ester liquids.
The insulating liquid sample is maintained at 120 °C in the presence of a solid copper catalyst
whilst bubbling air at a constant flow. The degree of oxidation stability is estimated by
measurement of volatile acidity, soluble acidity, sludge, dielectric dissipation factor, or from
the time to develop a given amount of volatile acidity (induction period with air).
In informative Annex B, a test method for evaluating the oxidation stability of inhibited mineral
insulating oils in the delivered state by measurement of the induction period with oxygen is
described. The method is only intended for quality control purposes. The results do not
necessarily provide information on the performance in service. The oil sample is maintained
at 120 °C in the presence of a solid copper catalyst whilst bubbling through a constant flow of
oxygen. The degree of oxidation stability is estimated by the time taken by the oil to develop a
determined amount of volatile acidity (induction period with oxygen). Additional criteria such
as soluble and volatile acidities, sludge and dielectric dissipation factor can also be
determined after a specified duration.
In informative Annex C, a test method intended to simulate the thermo-oxidative behaviour of
ester insulating liquids (headspace of air at 150 °C for 164 h) is described.
Additional test methods such as those described in IEC TR 62036 based on differential
scanning calorimetry can also be used as screening tests, but are out of the scope of this
document.

This standard may be applied, but only with caution, to other liquid-solid insulating systems.
In any case, the indications obtained should be viewed only as guidance and any resulting
action should be undertaken only with proper engineering judgment.

Insulating liquids - Determination of acidity - Part 3: Test methods for non mineral insulating oils (IEC 62021-3:2014)
EN 62021-3:2014

This part of IEC 62021 describes two procedures for the determination of the acidity of
unused and used electrical non-mineral insulating oils. Method A is potentiometric titration
and Method B is colourimetric titration.
NOTE 1 In unused and used non-mineral insulating oils, the constituents that may be considered to have acidic
characteristics include organic acids, phenolic compounds, some oxidation products, resins, organometallic salts
and additives.
The method may be used to indicate relative changes that occur in non-mineral insulating oil
during use under oxidizing conditions regardless of the colour or other properties of the
resulting non-mineral oil.
The acidity can be used in the quality control of unused non-mineral insulating oil.
As a variety of oxidation products present in used non-mineral insulating oil contribute to
acidity and these products vary widely in their corrosion properties, the test cannot be used to
predict corrosiveness of non-mineral insulating oil under service conditions.
NOTE 2 The acidity results obtained by potentiometric test method may or may not be numerically the same as
those obtained by colourimetric methods, but they are generally of the same magnitude.

Mineral insulating oils in electrical equipment - Supervision and maintenance guidance
EN 60422:2013

This International Standard gives guidance on the supervision and maintenance of the quality of the insulating oil in electrical equipment. This standard is applicable to mineral insulating oils, originally supplied conforming to IEC 60296, in transformers, switchgear and other electrical apparatus where oil sampling is reasonably practicable and where the normal operating conditions specified in the equipment specifications apply. This standard is also intended to assist the power equipment operator to evaluate the condition of the oil and maintain it in a serviceable condition. It also provides a common basis for the preparation of more specific and complete local codes of practice. The standard includes recommendations on tests and evaluation procedures and outlines methods for reconditioning and reclaiming oil and the decontamination of oil contaminated with PCBs. NOTE The condition monitoring of electrical equipment, for example by analysis of dissolved gases, furanic compounds or other means, is outside the scope of this standard.
