Influence of double excitation AC/DC in the reactive power demand of 3-phase transformers
(IEEE, 1999-12-01)
In this work it is discussed the performance of the reactive power demand in three-leg transformer core and three-phase transformer bank, under different conditions of AC/DC double excitation. In order to analyse the ...
Description of electric field-dependent dielectric permittivity in PMN ceramics
(2019-01-01)
The temperature dependences of the linear and nonlinear components of the dielectric permittivity of PMN ceramics were determined as a function of bias electric fields. The influence of the applied bias electrical field, ...
