Properties of Mineral Insulating Oils in Service
The infrastructure of the electricity grid and super grid system in the hitherto industrialized world was to a large extent built up in the decades following World War II with a peak in investments around 1960-1980. This means that the flotilla of power transformers is now starting to reach projected lifetime of around 40 years. During the last couple of decades there has also been an ongoin...
متن کاملOn the Mineral and Vegetal Oils Used as Electroinsulation in Transformers
Due to the relatively large availability and reduced price, the mineral transformer oils are widely used as electrical insulating liquids. However, mineral oil drastically degrades over time in service. New efforts were made to improve mineral oils characteristics, and other types of liquids like vegetal oils are proposed. This paper deals with new comparative tests on mineral and vegetal oils ...
متن کاملA Complex Permittivity Based Sensor for the Electrical Characterization of High-Voltage Transformer Oils
This work investigates the use of a specially designed cylindrical metal cell, in order to obtain complex permittivity and tanδ data of highly insulating High Voltage (HV) transformer oil samples. The data are obtained at a wide range of frequencies and operation temperatures to demonstrate the polarization phenomena and the thermally stimulated effects. Such complex permittivity measurements m...
متن کاملStatic secondary ion mass spectrometry investigation of corrosion inhibitor Irgamet39 on copper surfaces treated in power transformer insulating oil
Static secondary ion mass spectrometry was used to study the corrosion inhibitor Irgamet®39 on the surface of copper treated in insulating oils and the effect of temperature changes, by means of temperature programmed desorption experiments under vacuum, on metal coverage. Four commercial oils, both corrosive and noncorrosive, showed no significant influence on the stability of the tolyltriazol...
متن کاملPhysicochemical and Aging Tests of 2605SA1 and 2605HB1 Amorphous Ribbons for Power Applications
To evaluate the physicochemical compatibility of rapidly solidified ribbons with transformer insulating fluids, isothermal heating process was carried out in order to prove the sustainability of these materials. Fe-based amorphous ribbons were immersed in mineral and vegetable transformer oils for a period of 580 hours at 110 and 140°C. Chemical analyses of oils after experimentation have shown...
