Abstract

Nowadays, electricity is playing an important role in human daily life. Seen that it’s a high technology world, most of the thing has been store nor save as digital data in the electronic devices. Any of the power problem manifested in current, voltage, and the frequency deviation may result in the failure nor miss operation of customer equipment. Power quality problem such as voltage spike, noise, voltage unbalance, harmonic distortion, voltage fluctuation, interruption (complete loss of voltage), and voltage sags (drop) and swells (rises) can be short-duration nor long- duration voltage variation, they do affect much on the customer equipment (edvard, 2014). So the power quality of the power supply is important in order to protect customer equipment. The purpose of this final year project is to build an uninterrupted power supply also known as voltage stabilizer with residual current devices such as relay as the protection. The output of the power supply must be able to stable at 230Volts, and 50Hz in order to supply it to the other sensitive equipment.
