Electrical characteristic analyzer of single phase transformer using Pseudo Random Binary Sequence

摘要

PURPOSE: A device for analyzing electric property of single-phase transformer with PRBS(pseudo random binary signal) is provided to analyzing a system property easily in a high-frequency band by using a PRBS in describing a property of a single-phase transformer in a whole frequency band. CONSTITUTION: A PRBS generation unit(1) offers an energy for an electromagnetic reaction of a single-phase transformer(T). A measure board(2) uses a high-rate analog digital convertor which has a 40 MHz sampling. A computer(3) receives data of the measure board(2) and analyzes a frequency response property of the single-phase transformer(T) on the ground of the data.
