An Australian standard, the AS 1883-1992 standard applies to mineral insulating oils found in transformers, switchgear and similar electrical equipment, which originally complies with the requirements of the IEC 296 standard, where oil sampling is applicable and normal operating conditions as specified in the equipment specifications apply. The IEC 296 standard, developed by the International Electrotechnical Commission (IEC), describes the technical specifications for non-mineral insulating oils for transformers and switchgear.
The purpose of the AS 1883-1992 standard is to assist the power equipment operator in assessing the condition of the oil in the equipment and in their efforts to keep the oil usable. For this purpose, standard test methods are defined, evaluation procedures are suggested, and methods for oil regeneration and recovery are explained when necessary. It is recognized that oil in certain types of equipment may contain dissolved gases, the analysis of which can be useful in assessing the condition of the insulation system.
Briefly, in AS 1883-1992 standard, The reasons for the deterioration of the oil in use are explained and the test methods that give information about the condition of the oil are defined. It also makes recommendations for the processing and periodic inspection of oil.
Recently this standard has been further developed and the AS 60422 standard has been published (AS 60422-2017 Mineral insulating oils for electrical equipment - Inspection and maintenance manual). This new standard provides guidance on the inspection and maintenance of the quality of insulating oil in electrical equipment. This standard is applied to mineral insulating oils originally supplied in accordance with the IEC 60296 standard, in transformers, switchgear and other electrical equipment from which the oil sample is reasonably taken. This standard is also intended to assist the electrical equipment operator in assessing the condition of the oil and keeping it in serviceable condition.
The new standard also provides a common basis for the preparation of more specific and complete local codes of practice. This standard contains recommendations on testing and evaluation procedures, and provides methods for oil regeneration and recovery, and for the disinfection of oil contaminated with polychlorinated biphenyls.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides test services for the maintenance and inspection of insulating oils in use, within the scope of AS 1883-1992 standard, with its trained and expert staff and advanced technological equipment.
