THE STUDY 01 CHARACTERISTICS OF INRUSH CURRENTS FOR HIGH POWER SHORT-CIRCUIT TESTING TRANSFORMER

  • 발행 : 2006.07.12

초록

The inrush current of transformer cause saturation effects of recovery voltage for short-circuit power testing. the inrush current depends on the residual flux of the transformer core. when inrush current occurs, it is contains a d.c. component and the high harmonic content of the current are of importance to relay protection of testing circuit. this paper describes of decrease method of inrush current for high power short-circuit testing transformer.
