GSO IEC/TR 61946:2014 矿物绝缘油 石蜡/环烷绝缘油的性质特征 低温差示扫描量热法（DSC）测试方法

This technical report offers a test method for the classification of mineral insulating oils as either paraffinic or naphthenic, by means of low-temperature differential scanning calorimetry (DSC). For the purpose of this technical report, the typical operating temperature range extends from –100 °C to +100 °C. The temperature range can be extended, depending upon the instrumentation used. The method is applicable to mineral insulating oils obtained from petroleum crudes. It may be also applied to mineral oils containing pour point depressants, as these additives do not prevent the formation of paraffin crystals but only the growing of such micro-crystals.

GSO IEC 62021-2:2014 缓冲液 酸度的测定 第2部分：比色滴定

This part of IEC 62021 describes a procedure for determination of the acidity of unused and used electrical mineral insulating oils. NOTE 1 In unused and used 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 a mineral insulating oil during use under oxidizing conditions that may or may not be shown by other properties of the resulting mineral oil. The acidity can be used in the quality control of unused mineral oil. As a variety of oxidation products present in used mineral oil contribute to acidity and these products vary widely in their corrosion properties, the test cannot be used to predict corrosiveness of a mineral oil under service conditions. NOTE 2 The acidity results obtained by this test method may or may not be numerically the same as those obtained by potentiometric methods, but they are generally of the same magnitude. The potentiometric method uses an endpoint at pH 11,3 to ensure titration of all species, whereas the colourimetric methods uses an indicator changing colour at approximately pH 9,5. This may lead to slightly higher results for oils with acidities above 0,3 mg KOH/g oil when using the potentiometric method.

GSO IEC/TS 61464:2014 绝缘穿透套管 解释绝缘穿透套管中溶解气体分析 (DGA) 的指南 其中油是底层绝缘材料（通常为纸）的浸渍介质

This technical report gives guidance for the interpretation of dissolved gas analysis (DGA) which has been developed for bushings, in service, where the main insulation (generally paper) is impregnated with mineral insulating oil according to IEC 60296. This technical report is applicable to oil-filled and impregnated paper bushings in service. Until further experience has been gained, the methods should be applied with caution in relation to other materials, e.g. synthetic hydrocarbons based on dodecylbenzene, according to IEC 60867. The indication obtained by the interpretation of a dissolved gas analysis of an oil sample taken out of a bushing should be viewed as a guide and any resulting action should be undertaken with proper engineering judgement.

GSO IEC 62021-1:2014 介电液体 酸度的测定 第1部分：电位法自动滴定

This part of IEC 62021 describes the procedure for the determination of the acidity of unused and used electrical mineral insulating oils. NOTE 1 In unused and used 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 a mineral insulating oil during use under oxidizing conditions regardless of the colour or other properties of the resulting mineral oil. The acidity can be used in the quality control of unused mineral oil. As a variety of oxidation products present in used mineral oil contribute to acidity and these products vary widely in their corrosion properties, the test cannot be used to predict corrosiveness of a mineral oil under service conditions. NOTE 2 The acidity results obtained by this test method may or may not be numerically the same as those obtained by colorimetric methods, but they are generally of the same magnitude.

GSO IEC/TR 61294:2014 绝缘液 局部放电起始电压的测定 试验程序

This technical report describes a test procedure to measure the pa rtial discharge inception voltage (PDIV). It is one of a group of methods which have been recently developed to describe the behaviour of insulating liquids when subjected to high electrical stress. The method is applicable to all types of insulating liquids used in medium and high voltage equipment. Nevertheless the equipment described in this repo rt may not be adapted to liquids with values of PDIV greater than 70 kV (see annex A). Complementary information may be obtained by the gassing properties (IEC 628) and the lightning impulse breakdown voltage (IEC 897) in addition to the widely used measurement of electric strength (IEC 156).

1.1 This method uses the change of electrical and/or chemical characteristics of transformer askarel to eliminate those materials which are not suitable due to their contaminating effect on the askarel. Delayed or long time contamination effects may not be detected. 1.2 This method also utilizes various physical tests on the electrical insulation and construction materials after controlled exposure to the askarel to eliminate those materials which are not suitable for further consideration. 1.3 This method is not suitable for the complete evaluation of the compatibility of insulating and structural materials with the askarels for any given application.

EN 62021-3:2014 绝缘液体 酸度的测定 第3部分：非矿物绝缘油的试验方法

IEC 62021-3:2014 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. 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.
