PROJECT DESCRIPTION: This work “design and construction of a power resumption alarm” research material is a complete and well researched project material strictly for academic purposes, which has been approved by different Lecturers from different higher institutions. We made Preliminary pages, Abstract and Chapter one of “design and construction of a power resumption alarm” visible for everyone, then the complete material on “design and construction of a power resumption alarm” is to be ordered for. Happy viewing!!!
Power supply and failure is a frequent experience that occurs in our mains. Power restoration is a period of time when the electricity supply to a particular building or area is restored, because of replacement or servicing damage to the cables or any other reason. For us to be notified when the power ON condition has occurred a power monitoring device is used. This system indicates when there is power resumption in our mains through alarm indication. As soon as the system experiences power resumption you will receive a signal from an alarm.

1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
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 [1]. 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. But how do you know that the remote site has experienced a power off condition?[1] For us to be notified when the power ON condition has occurred a power monitoring device is used. This system indicates when there is resumption in our mains through alarm indication. As soon as the system experiences power resumption you will receive a signal from an alarm [1][2].
1.2 PROBLEM STATEMENT
Power failure in homes, offices and workplaces can be irritating, frustrating and devastating, affect our appliances and at the same time affect the happiness of the occupant. It is quite unfortunate that sometimes when power is restored the occupant will not be aware most especially when there is noise and no lighting indicator. In other to overcome this problem, this device was designed. This device is designed to inform you when the power is restored in order to switch off their alternative power supply.
1.3 OBJECTIVE OF THE PROJECT
The objective of the project is to design a power failure monitoring device that will trigger a buzzer when the mains supply is restored. Once the buzzer blows it also indicate that the mains have been restored.
1.4 PURPOSE OF THE PROJECT
The purpose of this work is to build a power monitoring device that monitor power resumption.
This device is designed to inform you when the power is restored in order to switch off their alternative power supply.
1.5 SIGNIFICANCE OF THE PROJECT
Power restoration alarm notifies you by alarm when your electrical equipment suffers a power supply. If you have important equipment you want to run with mains 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 [2].
1.6 CONSEQUENCES OF A POWER FAILURE
- No lights in the house
- Loss of refrigeration – food spoils
- No heat or air conditioning
- No flushing toilets or running water
- Can’t cook on electric range or in microwave oven
1.7 APPLCATION OF THE PROJECT
Typical uses of power failure and resumption signal include monitoring [2][3]:
* fridges/freezers;
* fish tanks/aquariums;
* sump pumps;
* computer equipment;
* heating systems;
* chemical storage;
* and many other applications.
1.8 SCOPE OF THE PROJECT
This project is a power supply monitoring device that will trigger a buzzer when the mains supply is resumed. At the same time, the light emitting diode will be turned ON. Once the buzzer sound, one will know that there is resumption of mains supply [3].
1.9 METHODOLOGY
To achieve the aim and objectives of this work, the following are the steps involved:
- Study of the previous work on the project so as to improve it efficiency.
- Draw a block diagram.
- Test for continuity of components and devices,
- Design of the alarm was carried out.
- Studying of various component used in circuit.
- Construct the circuit.
- Finally, the whole device was cased and final test was carried out.
