Italian experience in distribution transformers optimisation and operation

摘要

The suitable optimization and the correct operation of a large MV (medium voltage)/LV (low valtage) distribution fleet requires the knowledge of several elements, such as: transformers fleet composition and the trend of growth of the same; no-load and on-load losses of the several transformer classes belonging to the concerned fleet; service procedures in order to evaluate the amount of loss of the whole fleet either by using mathematical models and/or through service experiences, whether the adopted improvements have been useful in limiting the amount of power lost and in upgrading the transformer operation.
