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

ABSTRACT
The wide-scale deployment of IEE 802.11 wireless networks has
generated significant challenges for Information Technology (IT) departments
in corporations. Users frequently complain about connectivity
and performance problems, and network administrators are expected
to diagnose these problems while managing corporate security
and coverage. Their task is particularly difficult due to the unreliable
nature of the wireless medium and a lack of intelligent diagnostic
tools for determining the cause of the ....etc

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

A good bread should be judged by its volume, bloom, shape, colour, texture, sheen, moistness and flavour. In general, one should examine the external area and the internal (crumb) area of the bread.

Bread faults can occur as a result of a series of small faults interacting together. Some faults may be inter-related yet others are independent. Flour varies in grade, in gluten content and quality. Colour also varies and so does the maltose content. In my bakery, when examining the faults in a loaf of bread, the temperature and timings, methods ....etc
