PROJECT 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 MOSFET 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 microcontroller from the 8051 family.

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.

Q & A
Q:  Which microcontroller is used in this project?
A:  The microcontroller used in this project is a 40 pin IC from 8051 family.
Q:  What is the role of microcontroller in this project?
A:  The microcontroller is used to develop a dynamic timing
Q:  What is the difference between Electronic circuit breaker and normal circuit breaker?
A:  Normal circuit breaker is dependent on thermal bimetal lever trip mechanism, whereas Electronic circuit breaker is formed using current sensing element and comparators
Q:  Will it auto return after fault (overload) clearance?
A:  No, one has to restart the device, as it would toggle between on and off till overload condition is cleared.

I came to know about Edgefx because one of my collegiate named Anurag the keyword used like website URL.For submitting & personally there is no time to go to shop and take the kit from my premises hence I ordered through online. I like everything like it is pretty well, neatly assembled and well build.Yes the kit delayed for a day.I purchased through online. No it’s pretty well.
