A novel bench size model coalescer: Dehydration efficiency of AC fields on water-in-crude-oil emulsions

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1385596

We describe herein the design of a small AC electrostatic model coalescer for investigating coalescence efficiency of water in oil emulsions. The function of the model coalescer is tested on emulsions with different water cuts. In the coalescer, coalescence takes place in a couette flow in the bulk ...

Self-healing composites for high voltage electrical insulation

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258142

A self-healing electrical insulation material for high voltage apparatuses has yet not been developed. Such a material would have been very attractive for electrical components installed in conditions were service failures cause time consuming and very expensive replacements. This paper reports resu...

Liquid insulation of IGBT modules: Long term chemical compatibility and high voltage endurance testing

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1385622

To facilitate operation of power electronics for subsea operation at ambient pressure components have to be submerged in a liquid. Equipment and schemes for testing of long term properties have been developed. Several techniques were used to investigate compatibility between a silicone gel and vario...

Absorption of water in silicon gel

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1162815

Water is an important enemy of an electric insulation system. Water vapour can be absorbed by electrical insulation materials (liquids or solid) and migrate in between the materials to achieve the same relative humidity equilibrium everywhere. Water can reduce withstand voltage of the insulation liq...

Self-healing high voltage electrical insulation materials

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1142937

Electrical treeing can be the precursor to catastrophic failure for electrical insulation materials and hence significantly shorten their service lifetime. Considering that damage inside the composites (thermoset insulation materials containing fillers) is difficult to detect and particularly to rep...

Esterification of low molecular weight acids in cellulose

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1133456

The interaction between low molecular weight acids dissolved in mineral oil with cellulose has been studied. The formation of esters as a function of temperature has been demonstrated using attenuated total reflection infrared (IR) spectroscopy. Higher temperatures lead to a shift towards ester form...
