Analysis of load test, transformation, turns ratio, efficiency and voltage regulation of single phase transformer

Abstract

This paper presents analysis obtained for the design of single phase transformer. The method is simple, efficient and accurate, by an exhaustive analysis. The following constraints are imposed: excitation current, load fractions, efficiency and voltage regulations. The methodology of this paper requires only two input data: primary side of the transformer and the secondary side of the transformer. The input side of the transformer include the following parameters; voltage, current and power while the secondary side of the transformer includes; voltage, current, efficiency, voltage regulation. These data are included in the transformer nameplate. In this paper, the minimization of the following four objective functions is considered: total owing cost, mass, total losses and material cost was considered.The consideration of these four objective functions is implemented automatically by running the analysis several times without intervention of a designer. Consequently, transformer manufacturers save design man-hours and increase capacity. The optimized solutions of transformer design are validated with laboratory and process measurements. In this paper the simulation of single phase transformer with different supplies such as Load Test and efficiency of voltage regulation are carried out.
