摘要： To characterize an electrical component, namely a medium or high voltage transformer, electrical motor or generator, a two-step procedure is carried out. In a first step, a set of terminal configurations are applied to the terminals (p1, . . . , pn) of the component in order to obtain data describing the linear electrical response of the component to any pattern of voltages uk or currents ik applied to the terminals (p1, . . . , pn). Typically, such data is e.g. expressed in terms of an admittance matrix Y or impedance matrix Z or, by the set of current and voltage vectors (ik, uk). Using this data, the linear electrical response of the component 1 under a test terminal configuration can now be calculated in a second step. This procedure allows to determine the response under any desired test terminal configuration without the need to carry out the measurement under the test terminal configuration.

摘要： Residue perturbation is used for enforcing passivity of a linear response model of an electrical component having n>1 ports. According to an exemplary embodiment, a modal perturbation approach can be used, which allows weighted perturbation of the individual modes by the inverse of the corresponding eigenvalues. This provides superior results if the admittance or impedance matrix of the device has a large eigenvalue spread.

摘要： A method and device characterize linear properties of an electrical component having n>1 ports. The linear properties of the component are described in a matrix relating a voltage applied to the ports to a current through the ports. A frequency dependence of the matrix is approximated to preserve eigenvalues of the matrix by a pole-residual model. The method includes: (a) obtaining a set of values of the matrix at discrete frequencies, and obtaining eigenvalues and eigenvectors for each value; (b) fitting a set of vector equations to the eigenvalues and eigenvectors with a first set of pole frequencies; and (c) calculating a second set of pole frequencies by a vector fitting process for all modes of an element of the matrix. Steps (b) and (c) are repeated using the second set of pole frequencies in step (c) in a subsequent step (b) until a stop condition is met.

摘要： Rational macromodeling of multiport devices is disclosed that can ensure high accuracy with arbitrary terminal conditions. This can be achieved by reformulating a vector fitting technique to fit eigenpairs rather than matrix elements, and weighting can be chosen equal to an inverse of an eigenvalue magnitude in order to achieve a relative accuracy criterion for the eigenvalue fit. The procedure can improve accuracy for cases with a large eigenvalue spread. Impedance characteristics of an adjacent network can be used to lessen the complexity of the fitting and to improve accuracy.

摘要： A method and device for determining the linear response of an electrical multi-port component has an “estimation procedure” in which an estimated admittance matrix is determined by applying voltages to the ports of the component and measuring the response of the component. The estimation procedure can e.g. consist of a conventional measurement of the admittance matrix. The method further has a “measurement procedure” in which several voltage patterns are applied to the port. The voltage patterns correspond to the eigenvectors of the estimated admittance matrix. For each applied voltage pattern, the response of the component is measured. This allows to measure the linear response of the component accurately even if the eigenvalues of the admittance matrix differ by several orders of magnitude.

摘要： Some of the embodiments of the present disclosure provide a method for analyzing a substance, where the method includes subjecting the substance to a dynamic excitation to produce an observable response, and determining a characteristic quantity of the substance based on a correlation between the excitation and the response. The correlation between the excitation and the response is expressed by a parametric model for which a specific model structure with a finite number of unspecified parameters is preset. The determining a characteristic quantity of the substance includes calculating the parameters of the model from values of the excitation and the response in a time domain, determining from the calculated parameters a transfer function in a frequency range, and calculating the characteristic quantity directly from the transfer function. Other embodiments are also described and claimed.

摘要： The electrical insulator has an insulator body 3 which is fitted between an electrical conductor 1 and a grounded holder 2. The surface of the insulator is at least partially formed by a protective body 6. The material of the protective body has a low dielectric constant in comparison to that of the material of the insulator body 3. The protective body 6 prevents an electrically conductive particle 12 from coming to rest directly on the surface of the insulator body 3, in particular in the region of the triple points T, or causing a considerable increase in the field due to immediate proximity to the insulator body 3. The breakdown voltage of a gas-insulated system which contains such insulators provided with a protective body is increased. Gas-insulated systems can thus be made more compactly and more cheaply, and their life can be extended.

摘要： Substance analysis based upon observed reponse to excitation described herein. When a substance is subjected to an excitation and a response is observed, a relational evaluation is made based on the concept that the parameters of a mathematical model may be determined, which emulate the relationship between the excitation and the response, and that characteristic substance properties are subsequently determined/calculated from the time series of estimated values of the mathematical model.
