Abstract

"PROCESSO DE DETECçãO E DE LOCALIZAçãO DE FONTE DE DESCARGA PARCIAL EM UM APARELHO ELéTRICO". A presente invenção refere-se a um processo de detecção e de localização de uma fonte de descarga parcial em um aparelho elétrico instalado em um compartimento contendo um fluido acusticamente condutor. Ele consiste em: - posicionar (31) detectores acústicos e adquirir a posição dos detectores; - definir (35) grupos de detectores que têm pelo menos três detectores; - se assegurar (37) que cada grupo está isento de triângulo, com vértices materializados por três detectores, dos quais pelo menos um ângulo está fora de uma faixa de ângulos, senão eliminação do grupo; - para cada grupo não eliminado, calcular (38) uma posição aproximada da fonte; - assegurar-se (39) que cada grupo, não eliminado, está isento de triângulo, com vértices materializados por dois detectores do grupo e pela posição aproximada, do qual um ângulo está fora da faixa, senão eliminação do grupo; - calcular (43) a posição buscada da fonte, por média das posições aproximadas para o total ou parte dos grupos não eliminados.
