چکیده مقاله:

Standards were developed as early as the late 19th Century for the purpose of harmonizing the properties of certain products and processes and thus rendering them comparable. Specific dimensions and technical properties are defined in accordance with the specifics of a standard. Needless to say that the world of transformers is equally governed by standards, and that without a doubt, much effort has been invested in the creation of viable guidelines and principles useful for the various different applications. Without a doubt, a general distinction can be made between two fundamentally different types of standards: - Standards created to define a specific design or technical feature - Standards created to facilitate or define the evaluation of data In the world of transformers, both types of standards have their established place. It could be said that one type of standards represents the hard standards established to specify particular data and features in a mandatory and measurable manner. Whereas the other type of standards is based on empirical values gained by experience which may not be measurable in every single case. In many cases, the answers provided in such documents may be somewhatvague or relative and may therefore be valid only under certain marginal conditions. Especially where the evaluation of data from DGA and oil testing is concerned, to focus tends to be rather on the soft side. That is why there is a huge margin for interpretation - especially what with the collision of two fundamentally different worlds and philosophies, i.e. the world of IEC and the world of IEEE. And it takes a due and careful account of these fundamentally different ways of thinking and working to allow for a reasonably comparability and joint application. However, background efforts must be made at all times to comply with the general physical rules.
