Abstract

A prototype system of relay has been design and construct based on the literature review. The prototype system solved the problem from problem statement which was detected electric fault and triggered the relay to prevent incident and downtime caused by electrical faults. The prototype system served as a protector to protect electrical devices from faults. It is used to able detect earth faults and alert to the user. Besides that, the prototype system also indicated the faults line and display amount of current leakage on the LCD display. The prototype system operated based on Arduino Uno as microcontroller. First of all, the microcontroller connected to the component such as two ACS712 current sensors, LED indicator with 500 ohm resistor, LED as relay with 500 ohm resistor, buzzer with 500 ohm and 16x2 LCD display. The prototype designed system measure two individual current lines. When current leakage occurred, the prototype design system calculated the current leakage and display on the 16x2 LCD display to show to user. Furthermore, it alerted the user with sound and lighted the LED as indication. The relay triggered by received the signal from the microcontroller. The operation operated continuous either the fault is clear or fault occur. The prototype system expected to detect earth fault and alert the user by indicating the current leakage on the LCD display. The system also expected to alert the user through sound and light and trigger the relay as fast as possible.
