Title (EN) METHOD FOR PROTECTING TRANSFORMERS AGAINST INNER FAULTS
(FR) PROCÉDÉ DE PROTECTION DE TRANSFORMATEUR CONTRE LES DÉFAILLANCES INTERNES
(PT) MÉTODO DE PROTEÇÃO DE TRANSFORMADOR PARA FALTAS INTERNAS
Abstract: front page image
(EN)The present invention relates to a method for protecting transformers against inner faults. In short, the method disclosed in the present invention is aimed at increasing the detection sensitivity of inner faults in devices, mainly power transformers, but is also useful for detecting inner faults in other devices, such as motors, generators, shunt reactors, capacitor banks, transmission lines and even a combination of multiple devices in the protection zone. The present method increases the sensitivity to inner faults, thereby reducing operation times and damages to devices protected by this method.
(FR)La présente invention concerne un procédé de protection de transformateur contre les défaillances internes. En résumé, le procédé de l'invention vise à augmenter la sensibilité de détection de défaillances internes dans des équipements, notamment des transformateurs de puissance, mais peut également être utilisé dans la détection de défaillances internes dans d'autres équipements, tels que des moteurs, des générateurs, des réacteurs shunt, un banc de condensateurs, des lignes de transmission, voire la combinaison de plusieurs équipements dans la zone de protection. Le présent procédé permet d'augmenter la sensibilité aux défaillances internes, réduisant ainsi les temps d'actionnement et favorisant une réduction de l'endommagement des équipements auxquels cette protection est fournie.
(PT)A presente invenção refere-se a um método de proteção de transformador para faltas internas. Em suma, o método revelado na presente invenção se propõe a aumentar a sensibilidade de detecção de faltas internas em. equipamentos, principalmente/ transformadores de potência, mas podendo ser também, empregado na detecção de faltas internas a outros equipamentos como motores, geradores, reatores shunt, banco de capacitores, linhas de transmissão e até mesma para a combinação de mais de um equipamento na zona. de proteção. O presente método atua aumentando a sensibilidade para as faltas internas, diminuindo, assim, os tempos de atuação e promovendo uma redução no dano cios equipamentos sob a proteção que fornece.
