Based on the Preisach theory in hysteresis, this paper presents a novel transformer core model. Unlike existing mathematical-based hysteresis models, the proposed model is based on a physically correct hysteresis model and can precisely represent the actual behaviors of magnetic materials. In addition, the experimental results of a ferroresonance test of a Voltage Transformer (VT) are presented...

This article considers the issue of wide implementation in various branches national economy caused intensive growth electric machines production. Due to high specific consumption magnetic materials production machines, a very promising direction is development waste-free technology manufacture cores and by methods powder metallurgy. The use metallurgy allows reducing losses electrical steel el...
Soil organic C content, a major source of system stability in agroecosystems, is controlled by many factors that have complex interactions. The purpose of this study was to evaluate the major controls over soil organic carbon content, and to predict regional patterns of carbon in range and cultivated soils. We obtained pedon and climate data for 500 rangeland and 300 cultivated soils in the U.S...
