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

Respected sir,

with due regards that i am Ravi Mishra student of B.Tech EE 3rd year in M.I.T.,Moradabad.i wants to inform you that i have no much content about my seminar topic APPLICATION OF HAAR FUNCTION IN ESTIMATION OF TRANSMISSION LINE FAULTS/TRANSFORMER FAULTS.so i request you to give some information about this topic.

thanking you,

Identifying Transformer Incipient Events for Maintaining Distribution System
Reliability
Abstract
This paper presents the time domain and timefrequencydomain analysis results of incipient events insingle-phase distribution transformers. This analysis willaid in the development of an automatic detection methodfor internal incipient faults in the transformers. Thedetection method can provide information to predictfailures ahead of time so that the necessary correctiveactions are taken to prevent outages and reduce downtimes. The analyz ....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
