Efficient fault detection of distribution transformers has great worth when installation of distribution transformers in the field is taken into account. Computer software has been developed which makes it possible to detect the region of fault location and evaluate the strength of insulation puncturing. It is capable of locating the position of fault along with total percentage of insulation breakdown region. Different evaluation tests are performed which are capable to recognize not only visible faults but also those faults in the windings of distribution transformers which cannot be...

This project book claims the achievement of successfully implementation of RS encoder and decoder. First the transmitted message was received by the receiver without introducing errors; next step is to introduce the errors after that the position of error bits were identified and corrected using algorithms at the decoder side. The decoding is carried out by first calculating syndromes secondly determining error location polynomial and error magnitude polynomial, then finding error positions and calculating error values and correcting the message in its received pattern.
