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...
متن کاملMoisture 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...
متن کاملFractal 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 ...
متن کاملOptical, Electrical and Electromechanical Measurement Methodologies of Field, Charge and Polarizatio - Dielectrics and Electrical Insulation, IEEE Transactions on [see also Electrical Insulation, IEEE
A selective review is presented of the use of optical, electrical, and electromechanical measurement methodologies of the electric field, charge, conductivity, and permittivity in dielectrics. Kerr electro-optic measurements are presented to demonstrate how volume charge distributions can distort the electric field distribution :significantly and how the field and charge distributions depend on...
متن کاملAlternative use of the electrical burn appliance.
Electrical burns to the oral commissure result in significant contracture, with resultant microstomia and severe disfigurement if left untreated. Successful management requires the skills of both the pediatric dentist and plastic surgeon, and good cooperation from the patient and parents. Splinting appliances reportedly have reduced the possibility of scar contracture following a burn to the li...
