Transformers are very important device for transfer of electrical energy. To protect transformer against different types of faults, various methods get used. In this paper, overload protection is established for protection of transformer. Microcontroller based relay is used for protection of transformer. Simulation circuit is...

As early as the year as 1900, automobiles were powered by electricity, gasoline and steam power. Electric vehciles were not sufficiently powerful at the time and just like steam powered cars were not successful. Only gasoline powered vehicles were developed further and thanks to quick...

Abstract – The primary issue with employing chalkboard is adverse consequences of chalk-dust particles causing health complications like Asthma, Dermatitis including Inflammation in eyes. The contact-electrification serves as basis. Air-ionizer is utilized for electrifying chalkboard surface on which chalk dust particles adheres to. The chalk-dust...
