Abstract

A computer-aided testing program for electrical apparatus (CATEA) is designed to test the performance of single and polyphase electrical devices. It has been applied to measure the losses of single- and three-phase AC and DC electrical machines, single- and three-phase transformers with linear and nonlinear loads. On-line measurements of iron-core and copper losses of singleand three-phase transformers with rectifier load are presented and compared with the results of the open- and short-circuit tests
