The objective of this projectwas to design and develop a protection device that would protect electrical equipment from main power disturbances. Most of industrial and household equipment require a supply of electricity for their operation. It is therefore important to take measures to prevent power quality disturbances and interruptions that may affect the operation of anyequipment. Mains power disturbances may cause inefficient operation of electrical equipment and damage to them. The methodology of this project includes literature survey, design, construction of prototype model, performance parameters measurements and documentation of development progress. Literature survey was done to learn different types of electrical disturbances, their consequences, as well as the existing protection devices used in preventing the effects of these disturbances on electrical equipment. The designed device is to be used specifically for the protection of household electrical equipment from under and over voltage as well as frequent mains power interruptions. This protection device will disconnect household electrical equipment from mains power during the occurrence of under and over voltage, as well as frequent mains power interruptions. This device was put to test under different electrical conditions such as changes in voltage, frequency, load etc. The device shows that it can operate satisfactory under the parameters tested.
