摘要：
A monitoring algorithm based on wavelet transform and fuzzy logic was developed in this paper to perform event classification in power transformers. These events were observed in an electrical power system simulated using the alternative transients program software. It should be emphasized that the modeled system presented transformers connected in parallel, which allowed the study of specific operational events, including sympathetic inrush. The proposed algorithm presented a satisfactory performance to many situations, identifying the causes of the differential currents, either caused by faults or other operation conditions. © 2013 Brazilian Society for Automatics - SBA.
