In Situ Preparation of Epoxy-SiO2 Nanocomposites as High Voltage Insulation
Compatibility of liquid and solid insulation materials for high voltage subsea connectors
The main objective of this study is to identify reliable insulation materials and systems for novel AC and DC subsea power connectors for oil and gas exploitation. A combined solid-liquid insulation system might be radically altered if the materials are not compatible. Different combinations of rele...
Epoxy-Based Nanocomposites for High-Voltage Insulation: A Review
Epoxy nanocomposites, with inorganic oxide nanoparticles as ﬁller, can exhibit novel property combinations, such as enhanced mechanical strength, higher thermal conductivity, increased dielectric breakdown strength, and reduced complex permittivity. Therefore, they have interesting applications in n...
Comparison between synthetic ester and mineral oil impregnated transformer paper aging markers
For transformers in service, aging markers from cellulose in oil such as furans, water, methanol and acids are measured for diagnostic purposes. The content of these indicators, measured in oil, may therefore vary with load, temperature, solid and liquid insulation aging, as well as marker stability...
Electrocoalescence III : staus and summary report from activities
A novel bench size model coalescer: Dehydration efficiency of AC fields on water-in-crude-oil emulsions
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-assembly and characterization of transferrin-gold nanoconstructs and their interaction with bio-interfaces
Transferrin (Tf) conjugated to gold nanoparticles and clusters combine the protein's site-specific receptor targeting capabilities with the optical properties imparted by the nano-sized gold. We have described two different synthesis protocols, one yielding fluorescent Tf-stabilized gold nanocluster...
