ABSTRACT: Transformer winding deformationis
one of the main types of transformer faults.
To check if a power transformer is being under winding deformation, the
transformer can be connected in a current transformer during its testing. A
transformer winding simulating model is set up under this connecting manner.
Then the simulation has been performed withcurrent source which is
the frequency sweep power. The simulation results show that the winding
deformation can be reflected effectively with current
source method.This
method lays the foundation for the realization of on-line monitoring and
diagnosis of the transformer
neutral directly grounded side winding.
