A novel Web based Expert System Architecture for on-line and off-line fault diagnosis and control (FDC) of transformers

The paper presents the structure and usage mode for an integrated fault-diagnosis and control system for transformers. The fault diagnosis and control system allows on-line analysis on a desktop application, a web application and off-line analysis for determining the transformer faults and remedies based on certain symptoms observed on the equipment and their comparison with the survey results of Cooling system condition, Bushing condition, Insulation system condition, Partial discharge evolution, Transformer switching in/switching off, exceeding of monitored parameter limits and estimation of remained life, the data of which is continuously updated into the database of the existing system.
