Description
ABSTRACT
Power restoration is a period of time when the electricity supply to a particular building or area is restored, for example because of replacement or servicing damage to the cables or any other reason. Modern equipment requires a continuous supply of electricity. Not only industry, but also in the household. Take the case of a refrigerator. If you experience a power off situation, your food will be spoilt.
Power restoration alarm is a monitoring device that will trigger a buzzer when the mains supply is restored. This device is helpful to inform the restoration of power supply to some critical installation such as a pump in a fish tank. Once the buzzer sound, one will know that there is a restoration of power supply and actions need to be taken to switch ON and OFF all necessary appliances.

CHAPTER ONE
INTRODUCTION
- Background of the Study
Service restoration is one of the most mission-critical processes at a utility. When the lights go out, it’s the utility’s top job to restore service. Many utilities create storm response organizations that are activated when a large-scale outage occurs, and utility personnel immediately jump into their role in that organization.
Without a smart grid, the outage response process relies heavily on partial information and incomplete visibility (Ashutosh, 2020). Moreover, utilities continue to depend heavily on customer calls to report outages – and they lose valuable restoration time waiting for customers to report outages, especially when outages occur in the middle of the night.
Fortunately, with a smart grid, utilities can take advantage of a variety of specific real-time technologies that help address these limitations. AMI meters play a crucial role in speeding service restoration. They deliver immediate last gasp alarms whenever power is lost and service restoration notifications when service is restored.
In modern society, it is impossible to imagine life without electricity. Modern equipment requires a continuous supply of electricity. Not only industry, but also in the household. Take the case of an ordinary refrigerator. If you experience a power off situation, your food will be spoilt. But much more important, what if the power failure “spoils” your business. For example, uninterrupted power supply is needed for your server, which manages your accounting programme or provides uninterrupted operation of your website(Ashutosh, 2020).
Of course, in most critical applications, uninterruptible power supplies (UPS) are used, but this is not always the case. Also, these devices cannot provide continuous operation in the event of remote power off. Often you need to take other action according to the situation.
For us to be notified when the power ON condition has occurred a power supply signal device is used. This system indicates when there is power failure through alarm indication. As soon as the system experiences power failure you will receive a signal from an alarm.
- Statement of the Problem
Most of the time in our homes the occupant of the house will not be able to notice when there is power resumption most cases is when the occupant is using a standby generator, even when the neighbors are giving a noisy indication the occupant may not be able to hear it due to the noise of the standby generator. This simple device brings solution to this problem. Here is a simple power resumption alarm circuit that can be fixed inside the switch box itself. It gives beeps when the power resumes after a power failure. This circuit is ideal to monitor battery chargers, since the long duration power failure may sometimes remain unnoticed.
1.3 Purpose of the Study
The purpose of the project is to design a power supply monitoring device that will trigger a buzzer when the mains supply restoration. Once the buzzer sounds, one will know that there is a restoration of power supply and actions need to be taken to rectify the situation by providing alternative power supply or relocating the installation. The LED is used for visual indication so that even a deaf person can as well know when there is power resumption.
1.4 Significance of the Study
The power restoration alarm is intended to be installed on a manual transfer panel or generator-ready load center. During a power outage, when the main breaker has been turned off to allow the generator to provide emergency power to the panel, the power outage can be activated and will emit a pulsing 105dB alarm when the power outage ends and utility power is again available.
Power restoration alarm notifies you by alarm when your electrical equipment suffers a power supply. If you have important equipment you want to run and want to know if there has been a power supply so that you power the device, this app can help you by telling you when electric power is supplied.
1.5 Scope of the Study
The scope of this work covers building a Power restoration alarm using IC555 which is wired in a monostable mode, and few other components
CHAPTER FIVE
5.1 CONCLUSION
At the end of this work, the aim of the construction was achieved which is to design alarm circuit will alert you whenever there’s a power supply in the mains. In some special conditions it becomes imperative to know whether the mains that powers some important system or circuit is present.
5.2 RECOMMENDATION
This project is designed to be used in homes and industries and wherever the need for an indication of power supply is needed. And should be used and maintain by a qualified personnel.
