与所谓的“寿命损失”或配电变压器的绝缘老化相关的问题在很长一段时间内一直是令人感兴趣的。自上个世纪开始以来，各种概念已被用来解释变压器寿命损失，但通常这些概念都被错误地解释。事实上，“生命损失”一直被理解为“减少隔离的生命损失”。IEEE和IEC标准在确定配电变压器老化的方法上存在着热工差异。本文对这些标准中定义的变量进行了比较分析。所提出的分析涉及具有以下参数的Transformer：630 kVA，10/0.4 kV，Dy 5。
Problems related to the so called "loss of life", or isolation aging of distribution transformers, have been interesting over a long period of time. Since the beginning of the last century various concepts have been used to explain the transformers loss of life and as usual those are interpreted incorrectly. In fact, "loss of life" has always been understood as "reducing the isolation's loss of life". There are existing therminological differencess in IEEE and IEC standards, that are used in the methods for determination of ageing in distribution transformers. This paper is comparative analysis between the variables, defined in those standards. The presented analysis relates to a transformer with the following parameters: 630 kVA, 10/0,4 kV, Dy5.
