Petri net based transformer fault diagnosis [PDF]
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004 The reduction of the time needed for transformer fault diagnosis is an important task for transformer users. In this paper, Petri nets are exploited, in order to simulate the transformer fault diagnosis process and to define the actions followed to repair the transformer.

Improved RAkEL’s Fault Diagnosis Method for High-Speed Train Traction Transformer
, 2023 The traction system is very important to ensure the safe operation of high-speed trains, and the failure of the traction transformer is the most likely fault in the traction system. Fault diagnosis in actual work relies largely on manual experience. This

Transformation of fault tree into Bayesian Network Methodology for Fault Diagnosis
Mechanics, 2018 Dans cet article, nous avons montré une application d'un outil d'aide à la décision qui est le FTBN, La combinaison de Bayesian Network (BN) avec Fault Tree (FT) est une approche intéressante pour diagnostiquer les systèmes mécaniques. Les réseaux bayésiens sont des outils qui fournissent des méthodes probabilistes robustes de raisonnement dans l ...

Fault Diagnosis of Power Transformer in Mine
IOP Conference Series: Materials Science and Engineering, 2020 Abstract In view of the ambiguity of power system transformer faults in mines, the traditional gas analysis method cannot directly judge the possibility of fault occurrence based on gas concentration. A fault diagnosis method for mine transformers based on intuitionistic fuzzy Petri nets is proposed.
