Ultra Fast Electronic Circuit Breaker

8,000.00

When the power supply is overloaded, a circuit breaker is an automatically operated switch that shuts down the power supply.
The current Flowing through the CTs, which are connected in series with the load, is what triggers the trip.
The goal of this study was to build a power supply that shuts down when it becomes overloaded by employing a super-fast electronic circuit breaker.

Description

DESCRIPTION

With an ever-increasing population, the need for and consumption of electric energy in the market has increased, as has the cost of equipment such as electrical and electronics.
So, one option for protecting the electrical system from overload or short circuit is to use an ultrafast-acting electronic circuit breaker.
When the power supply is overloaded, a circuit breaker is an automatically operated switch that shuts down the power supply.
The current Flowing through the CTs, which are connected in series with the load, is what triggers the trip.
The goal of this study was to build a power supply that shuts down when it becomes overloaded by employing a super-fast electronic circuit breaker.

When it was discovered that traditional circuit breakers, such as MCBs, took longer to trip, the idea of an electronic circuit breaker was born.
As a result, for sensitive loads, it’s critical to engage a tripping mechanism as quickly as feasible, preferably instantly.
The voltage drop across a series element proportionate to the load current, often a low-value resistor, is used to control the electronic circuit breaker.

This voltage is measured, rectified to DC, and then compared to a preset value by a level comparator, resulting in an output that powers a relay through the MOSFET to trip the load.
It is preferable to utilize a relay instead of a semiconductor switch since such solid-state switches will invariably fail in the event of an inadvertent short circuit.
The Arduino is used, and the program is dumped into it for the operation.
The unit is highly rapid, and it overcomes the slowness of thermal type circuit breakers such as MCBs, which are based on a thermal bimetal lever-trip mechanism.

The current sensing across a series element, commonly a CT, is used to create an electronic circuit breaker (Current Transformer).
The current is measured, and a comparator built into the Arduino compares it to a predetermined value proportionate to the voltage to provide an output that drives a relay through a MOSFET to trip the load very quickly.
