I wish to express my immense gratitude to God Almighty for his mercy, guidance and protection towards me for seeing me through the rigors of this work. I am greatly indebted to my supervisor Engr. Ejimofor for his kind gesture and whose critics lead to the achievement of this work. I also will remain grateful to the tremendous contribution of my lecturers Engr. Ojobor (the Dean of Engineering Faculty), Engr. Ejimofor (Head of Electrical Electronic Engineering Department), Engr. Mbah, Engr. Ochi, and all the staff of Electrical Electronic Engineering both academic and non academic staff for their intellectual upbringing. My special appreciation goes to my loving parents Engr. & Mrs. Chukwu A. Orioha, my grandparent, my uncles and aunties, my brothers and sisters whose moral and financial support cannot be over emphasized. Also my sincere gratitude and special regards to my friends too many to mention whose encouragement also lead to the success of this work.
Due to higher damage of our electrical appliances usually caused by under-voltage (low voltage) over-voltage (high voltage), or voltage fluctuation, there is need to use our appliances with voltage stabilizer. The automatic voltage regulator (AVR) is a device designed to regulate voltage automatically – that is, to take a fluctuating voltage level and turn it into a constant voltage level, low and high voltage to normal 220VAC output.
Voltage stabilizer is one of the most essential electrical appliances which is used by people in their day to day life. This device is used in homes, commercial establishments, Govt. establishments, financial institutions, education institutions etc according to their requirement. The people are procuring every necessary item to meet up with our normal and consumable voltage supply used to protect our appliances such as fridge, some high capacity electronic items.
The aim of this work is to assemble a 5kva voltage stabilizer. This device was assembled with a 5kva Transformer (Copper Wound) which ensures 220vac output supply which operates on 50Hz and, the entire relay used on the board was rated 60 amps.
