CONCLUSION

CONCLUSION (week 8 - finish research and prepare for presentation)

This project is designed in the form of hardware for three single phase transformers 230v to 12V of output for to develop an automatic tripping mechanism for the three phase supply system while temporary fault and permanent fault occurs. Here we used 555 timer with relay for the fault is temporary or permanent and the hardware will be done in final year project 2 next semester.

From this project, the upgraded circuit breaker instruments from old Earth Leakage Circuit Breaker (ELCB) has created and make it safer to human and protect them from electrical danger. The Automatic Earth Leakage Circuit Breaker (Auto-ELCB) is also can be used in factory with some modifying to make it suitable for the factory needed. Auto-ELCB is the solution for the temporary trip and the temporary trip is the most factor for the trip in Malaysia. Lighting is the common factor. So when the circuit breaker automatic turn on after the temporary fault, the power will continue supply into the house and the owner do not have to worry about their house. Alarm system also can continue active to guide the house and prevent from the thief while owner is not at home.

The concept in the future can be extended to developing a mechanism to send message to the authorities via SMS by interfacing a GSM modem so the breakdown information will directly go to the person in charged to repair and monitor the power supply for the building.
