Contributions on increasing safety in exploitation of power transformers by checking the stability to oxidation of the insulating oil

摘要

Because the electro insulating oils into operation not preserve their properties unlimited, presents some contributions on verification stability to oxidation of electro-insulating oils, in order to increase safety in exploitation of power transformers. The novelty is a cell to check the stability to oxidation of electro insulating oil. This cell is the subject of an application for patent, which is registered at OSIM Bucharest and which is presented in detail in the following.
