Description
The project is designed to shut down a power supply when it is overloaded by using a super-fast electronic circuit breaker. The concept of electronic circuit breaker came into focus realizing that the conventional circuit breakers such as MCBs take longer time to trip. Therefore, for sensitive loads, it is very important to activate a tripping mechanism at the shortest possible time, preferably instantaneously.
The electronic circuit breaker is based on the voltage drop across a series element proportional to the load current, typically a low-value resistor. This voltage is sensed and rectified to DC, and then is compared with a preset voltage by a level comparator to generate an output that drives a relay through the Relay to trip the load. The relay use in place of a semiconductor switch is preferred because such solid state switches would invariably fail in case of accidental short circuits. The unit is extremely fast and overcomes the drawback of thermal type. It uses a comparator and 555 timer IC.
Furthermore, this project can be enhanced by using a CT for galvanic isolation between mains and control circuit. Power electronic devices such as high power thyristors / IGBTs can be used for ultra fast operation compared to the relay methods.
Note
Super-fast electronic circuit breaker system for the good price for the engineering projects. It is very comparative engineering project. It is very good BE final year electrical microcontroller based project and this project is diploma based student is use. For the project is the embedded base project and comparator base project. This project is electrical, power electronics , core electronics based project,
Super-fast electronic circuit breaker is the without microcontroller based project for the good project, excellent project for the BE last year engineering student is use for the student is use electrical student is use. This project for the competitive project in the BE electrical core electrical without microcontroller based project last year engineering student for the electrical student in last year engineering student in the use. This project is power electronics, electrical and core electrical base project
