anisotropic dielectric constantlaminated wood insulationoiltransformerLaminated compressed wood is one of the most important insulation materials for liquid-immersed power transformers. It is used for pressure beams, platforms, coil clamping rings, lead and cleat supports, step blocks, and fasteners, e.g...
Temperature also affects the value of the dielectric constant although the effects are relatively small for hydrocarbon lubrication oils. The typical decrease in dielectric constant for hydrocarbon oils is about 0.0013 or 0.05 percent per degree Celsius. The density of the oil also influences the depen...
Starting from the Maxwell鈥揋arnett theory and Bruggeman theory, the effective dielectric constant of oil/water random composites is presented. The nonlinearity of the theory is obvious. The model is especially suited to study the dielectric properties of oil/water composites of different nature. The...

Considering the electric double layers between oil and water, a new "complex model" of dielectric constant of oil/water composites was built up. Starting from the Maxwell–Garnett theory and Bruggeman theory, the effective dielectric constant of oil/water random composites is presented. The nonlinear...

Fault information of machinery equipments is often contained in the process of lubricating oil wearing off.Meanwhile, the dielectric constant of the oil would changeaccordingly during the process. The principle of online oilcontamination monitoring based on dielectric constantmeasurement is proposed. The ...

A critical examination is given of a simplifying assumption made in an earlier calculation of the functional dependence of the integral dielectric constant of polar liquids on the applied field. It was assumed in this calculation that, for the cavity and reaction fields at all field strengths the...
