Cylindrical geometry electroquasistatic dielectrometry sensors - Dielectrics and Electrical Insulation, IEEE Transactions on [see also Electrical Insulation, IEEE

Semi-analytical models are used to simulate the response of periodic-field electroquasistatic dielectrometry sensors. Due to the periodic structure of the sensors it is possible to use Fourier transform methods in combination with collocation point numerical techniques to generate accurate sensor simulations much more efficiently than with the more general finite-element methods. The models pre...

Moisture solubility for differently conditioned transformer oils - Dielectrics and Electrical Insulation, IEEE Transactions on [see also Electrical Insulation, IEEE

It is important to monitor the moisture content of transformer oil in a transformer. One parameter of particular interest is the moisture solubility of transformer oil. It has been reported that transformer oils under different conditions have different solubility. Measurements of solubility for four different types of conditioned oil are presented in this paper: fresh Shell Diala AX oil, lab-a...

Fractal Image Compression for Classification of PD Sources - Dielectrics and Electrical Insulation, IEEE Transactions on [see also Electrical Insulation, IEEE

The fractal image compression technique has an unique feature due to which physical position of blockslregions in the input image can be extracted directly from the compressed data. Applying this technique, +-q-n partial discharge (PD) patterns (treated as an image) are compressed and stored as affine transformations. These transfornations then are used directly to extract the embedded pattern ...
