Table 4 Parameters of the model and the faults that impact them.
From: Condition monitoring and fault diagnosis of power transformer based on non-invasive measurement
Model parameter | Type of fault |
|---|---|
Resistances (\(R\)) | Disk broking, caulking damage and wearing of tap changer |
Series inductances (\(L\)) | Disk misrepresentation, local failure, core perversion, and winding short circuit |
Series capacitances (\({C}_{s}\)) | Insulation aging, moisture infiltration, and disk displacement |
Shunt capacitances (\({C}_{g}\)) | Disk displacement, large mechanical forces buckling, ingress moisture |
