It might seem Footnote 6 that there is an obvious answer to the question, 'What sort of explanation is involved in mechanistic explanation of a regular behavior?' The answer is that mechanistic explanations explain by laying out the structure and operation of the mechanism that gives rise to that behavior, i.e. showing its parts, arrangements, interactions, activities and the like.Operating Mechanisms. Operating mechanisms of type HMB and HMC from Hitachi Energy are designed for reliable switching in the entire product range of high voltage circuit-breakers from 52 kV to 1,100 kV. The circuit-breaker constitutes the last link in the chain of different apparatus which form part of the protection equipment for power supply ... ….
