Abstract
"PROCESSO PARA A SUPERVISãO DO ENTRE-FERRO RADIAL ENTRE O ROTOR E O ESTATOR DE UM GERADOR ELéTRICO E DISPOSIçãO PARA A REALIZAçãO DO PROCESSO". O processo para a supervisão do entreferro radial (10) entre o rotor (6) e o estator (8) de um gerador elétrico (2) deve proporcionar de forma especialmente confiável uma análise de forma do entreferro radial (10) durante a operação do gerador (2). Para isso é realizado um ciclo de medições em um estado de operação estacionário e compensado do gerador (2), realizado em intervalos de tempo regulares onde no ciclo de medições a partir de grandezas randómicas (50) do gerador (2), a partir de grandezas de influência atuais (80) do gerador (2) e a partir de dados de medição (100) do entreferro radial (10) são determinadas grandezas características (120) do entreferro radial (1 0) e uma determinação e avaliação da forma do entreferro radial (1 0) e do espaçamento entre o rotor (6) e o estator (8).
