The particle-dispersed composite material is assumed as a cell combination 10 in which unit cells 1 having a length a are combined together in an x-axis direction, a y-axis direction, and a z-axis direction and which has a length l in the x-axis direction, a length m in the y-axis direction, and a length n in the z-axis direction, the cell combination 10 is created in which a particle element or a medium element is assigned to each of the unit cells 1 in consideration of the number-based median particle diameter D 50 , the maximum diameter D max , the minimum diameter D min , and the geometric standard deviation σ g in the particle diameter distribution and a content of the particles in the particle-dispersed composite material, and a relative dielectric constant of the particle-dispersed composite material is calculated by assuming the cell combination 10 as a laminate in which layers having a thickness d in the z-axis direction are combined and layered in the z-axis direction and assigning a capacitance C Layer,h of each of the layers represented by Formula 1 below to Formula 2 below to determine a relative dielectric constant ε Total of the cell combination 10.

    摘要： The invention concerns a method for charging a structure (1) consisting of an insulating body (2) sandwiched between two electrodes (3, 4). Said method comprises the following steps: placing a Faraday cage (9) in contact with one of the electrodes (3) of the structure (1), the other electrode (4) being brought to a reference potential, introducing the electrodes from a controlled electron emitting device (6) in the Faraday cage (9), the electrons reaching the electrode (3) with which it is contacted, so as to charge the structure (1). The invention is useful in particular for determining the properties of insulating materials.

    摘要： Systems and methods for measuring the integrity of insulation components in electrical systems. In preferred embodiments, an active sensor is coupled to a test tap of a bushing, the active sensor having an electrical circuit electrically coupled to the test tap, and wherein the electrical circuit includes a high pass filter that divides the electrical circuit into a high frequency bus and a power frequency bus. A grounded high frequency voltage is injected into the test tap via the frequency bus circuit. Resulting voltages and currents may be measured and compared to a reference voltage to determine capacitances and power factors for both the inner and outer sections of the bushing. Once the capacitances and power factors of the bushings are known, grounded and ungrounded high frequency voltages may be injected to determine capacitances and power factors of a connected transformer or reactor.

    摘要： A fluid contamination analyzer (90) accepts data from a sensor array (94). The fluid is affected by a magnetic field stimulus (96) from a control driver (98). Alternatively, an electrostatic field exciter may be used. The sensors impedance as a function of field strength is an indication of the particles characteristics, when multiple sensors are separated by substantial distances, a system of communication links is used and the information is digested at a central location.
