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...

Semi-insulating Liquids

Charge separation near a liquid/solid interface is explored by the electrohydrodynamic pumping of Freon TF, transformer oil, and silicone oil using high voltage traveling waves. Liquid head displacement measurements show strong dependencies on peak voltage amplitude (1.0-2.5 kV), frequency (0.1-20 Hz), liquid viscosity (0.5-20 cS), and liquid conductivity to 10-9 0-lm-l ). Reverse pumping, oppo...

Oriental Rugs in the American Market

After the World War II was over, and due to the relative peace of mind, a population explosion occurred and baby boomers were born. This generation which is called “Generation X” entered the 80’s as the buyers of homes and consumers of furniture, bed, mattress and rugs. This was one of the reasons for huge increase in demand for Oriental rugs of the 80’s. In this short a...
