Selections of transformer differential relay using fuzzy logic application / Mohd Shamsul Ibrahim

This final project studies the digital relay for the main protection of power transformer. This protective relay should avoid unnecessary trips according to some problems and several criteria of currents. They must block the tripping during the magnetizing inrush current and rapidly operate the trip...

This protective relay should avoid unnecessary trips according to some problems and several criteria of currents.

The main objective of this study is to enhance the performance of digital relay by using a fuzzy logic application.
