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

Optimization of Distribution Systems To Transmit Power Under Single Phase Faults
INTRODUCTION
As Electricity industry continuously grows availability, quality, capacity and safety of electricity increasingly become a concern
Conservative expansion of existing structures not possible due to economic, social and technical factors new techniques to increase capability and reliability of lines devised.
Single phase faults are most frequent, and presently resulting to total ....etc

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

Modeling Transformers With Internal Incipient Faults
The Incipient fault detection in transformers can provide
early warning of electrical failure and could prevent catastrophic
losses. a transformer model to simulate internal incipient faults is described here. deteriorating insulation
models with an internal short circuit fault model are combined here for developing the fault model. based on the physical behavior of aging insulation and the arcing
phenomena an aging
model and an arcing model was combined in parallel.
