ABSTRACT

This paper describes in detail, field experiments performed on a single-phase, distribution transformer to study the behavior of transformer terminal parameters during internal winding faults. A custom-built transformer provided with external taps was used for these tests. The taps were used to stage various internal winding faults in the transformer. Terminal values of voltages and currents were monitored and the results presented. A comparison of these results with simulation results is also presented

Internal winding faults resulting from the degradation of transformer winding insulation can be catastrophic and hence expensive. In the new environment of deregulation, utilities therefore are needing inexpensive methods employed to detect such faults in the incipient stage.

The development of an accurate internal fault diagnostic technique for transformers must be based on analysis of quantities from faults scenarios.

Considering the safety of personal, the damage that will occur in the transformer, the consumed time, and related c ....etc

Abstract:
In this seminar the method used contains a degrading insulation model and a transformer internal short circuit fault model. Since deteriorating insulation involves two stages aging and arcing, the degrading insulation model is composed of an aging model and an arcing model connected in parallel. The degrading insulation model was combined with internal short circuit model, to simulate internal winding incipient faults ,Internal winding faults resulting from the degradation of transformer winding insulation can be catastrophic and hen ....etc
