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 cost, simula ....etc

CONSTRUCTION AND USE OF BROADBAND TRANSFORMERS

Under the guidance of :
Mr. Debashis Jena

INTRODUCTION


Wound magnetic devices that are designed to transfer energy over a wide frequency range
Most broadband transformers are wound on ferrite toroids or rods
Used in telecomm equipment
Balun or binocular cores are used for broadband transformers that must accommodate RF power

1. INTRODUCTION
Electrical energy is a major requirement for the economic and industrial growth of any country. Most of the electrical energy is generated from the combustion of fossil fuels (coal, oil, gas). The fossil fuels are not only limited in nature, but generating electricity with these fuels have serious environmental, economical and safety consequences.
Energy from the sun, water, wind biomass and the ocean is renewable, biomass clean and environment friends. India has sufficient potential to develop hydro-el ....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
