More and more components of electric power grids are on the verge of reaching their assumed maximum service life. Today's DSOs apply modern and optimised maintenance, as well as replacement strategies based on the knowledge of the actual condition of the operating electrical equipment. This enables an efficient and fair distribution of the limited budget over the individual grid areas. In addition to the condition of medium-voltage (MV) substations, knowledge of their ageing behaviour is essential for long-term, well-founded replacement strategies. The asset simulation tools used by DSOs are mostly based on the bathtub curve, which is intended to describe the hypothetical failure rate in the distribution grid versus time. This paper presents a new and innovative approach to derive condition-dependent ...
