Abstract
Quality of power supply system in an electrical circuit is needed. Poor quality power
supply may cause distraction and may even damage the system hardware/ electrical circuit.
One form of the disorder is the under/over voltage. To overcome this we need a protection
device that can detect the presence of interference under/over voltage and secure the
electrical equipment.
Under/over voltage relay based microcontroller ATmega328 is designed aiming to
detect the disorder under/over voltage on voltage single phase 220 V 50 Hz. Voltage limits
for nuisance under voltage is -5% of normal voltage (220V), whereas disruption over voltage
is +5% of the normal voltage. and delay settings for under / over voltage is 5 seconds. The
output of the relay is connected to the contactor, the contactor will disconnect the power
supply in case of disturbances under/over voltage.
From the results of tests performed, the relay under/over voltage ATmega328
microcontroller-based designed to work properly. Relay can detect disturbances under
voltage and over voltage -5% +5% of nominal voltage
