Over Voltage Protection for Household Equipments

This paper identifies the development of an over voltage protection in order to avoid damage in load side. Most of home appliances are expensive also more sensitive. This may get damaged due to the instabilities in ac mains supply. It can also lead to losses in the electrical circuit. These losses lead to low power factors and wastage of so much power. The fluctuations can cause great impact to the power quality and many precious and expensive equipment may be damaged. It is therefore advisable to have a tripping mechanism to protect the load. The voltage above the rated values are caused by a sudden decrease in load in a circuit having a poor or damaged voltage regulator. The over voltage may also be caused by a damage in the circuit or loose connections in neutral wire. anything above that will be considered as over voltage. Thus, we can protect the equipment from damage. By doing this, the proposed circuit is able to protect the electrical appliance. Overvoltage events, caused by lightning strikes, power surges, or electrical faults, pose a significant threat to household electrical equipment, leading to malfunctions, reduced lifespan, or complete failure. This paper discusses various overvoltage protection techniques to safeguard home appliances, including surge protectors, voltage regulators
