    Designing of transformer and implementation of a digital scheme for its protection against over fluxing, over loading and over heating
    (University of Management and Technology, 7/19/2012) Kiran Siraj; Kausar Khawaja
    In this modern age the protection of electrical system has been a challenging problem for all protection engineers. The transformation from analogue world to digital world has created vast scope of study for all protection engineers and has moved to more economical techniques for implementation as well. With advancement of microchips we were also attracted towards protection of transformer using microcontroller. Here we have chosen PIC microcontroller due to its special features like reprogram ability, built in Analogue to digital convertor (ADC). The transformer is backbone of every electrical power system. The various application of transformer has lead to its wide usage including substations to mini house household appliances. Thus protection has been compulsion. In this project, microcontroller based protection system of transformer has been designed and explained. The main purpose of this project is to provide protection against different faulty conditions in transformer such as Internal Faults, Short circuit, Overloading Overheating.
