GSM and Arduino Based Smart Circuit Breaker

A circuit breaker is an automatic electrical switch that protects a circuit from harm brought on by overload or short circuit. Linemen might suffer catastrophic electrical accidents when operated manually during maintenance time because of a lack of communication and coordination between the maintenance team and the personnel of the electric substation. The breaker can be set up so that only persons with a password and authorization can use it in order to reduce such accidents. We have created a circuit breaker (CB) that uses OTP as the key to operate the circuit breaker using a GSM module.

I. Introduction

A circuit breaker is a type of electrical safety device used to guard against overcurrent or short circuit damage to an electrical circuit. Its primary purpose is to stop the flow of current in order to safeguard machinery and lower the likelihood of a fire. A circuit breaker can be reset to continue normal operation, in contrast to a fuse, which can only be used once before needing to be replaced. An electrical power supply can be manually or automatically controlled and protected with the help of a circuit breaker, which is a switching mechanism. Extra attention should be taken when constructing a circuit breaker to guarantee that it can safely interrupt the arc produced when the breaker is closed because the modern power system deals with enormous currents. Security is a key issue in our everyday lives, so in addition to building the circuit breaker, particular attention should also be given to the lineman's safety. Critical electrical mishaps to lineman during electric repair occur as a result of poor communication and coordination between the maintenance team and the substation team. In order to prevent this, we created a password-protected circuit breaker. Since now the circuit breaker is password protected; only the person who knows the password can operate on it to do the circuit breaker operation. Its functionality is further extended through Sending OTP the corresponding person who oversees doing the circuit breaker operation.
