DESIGN AND CONSTRUCTION OF A POWER FAILURE ALARM
ABSTRACT
This project presents design and construction of power failure alarm with auto generator starting device. 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 programmed or provides uninterrupted operation of your website.
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 off condition has occurred a power failure 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 and at the same time automatically power an auto-powering generator through a high current relay.
Power Outage signal notifies you by alarm when your electrical equipment suffers a power outage. If you have important equipment running and want to know if there has been a power cut while you’re not around, this app can help. From Freezers to Fish Tanks and all things electrical, Power Outage Alarm can provide you with additional peace of mind.

INTRODUCTION
BACKGROUND OF THE PROJECT
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.
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?
For us to be notified when the power off condition has occurred a power failure 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.
Power Outage signal notifies you by alarm when your electrical equipment suffers a power outage. If you have important equipment running and want to know if there has been a power cut while you’re not around, this app can help. From Freezers to Fish Tanks and all things electrical, Power Outage Alarm can provide you with additional peace of mind.
Power failure may be caused by various factors: an overload on the power plant, a thunderstorm, cable breakage during excavations. Whatever the reason you will be notified as soon as the power failure occurred in your remote area and you can act accordingly. This system also will give a notification when the power was restored.
Power Outage Alarm works happily in the background on your Android device and will keep monitoring even when your device is asleep and the screen is off.
1.1 AIMS AND OBJECTIVES
Due to inconsistent supply of power, there is a growing need for an indication when there is power failure. This has lead to destruction of our electrical appliances in industry, hospitals, schools and homes. The problem of power failure can be checkmated with the use of stand-by generating set after an indication.
Sequel to the rate at which more sophisticated electrical/electronics gadgets are being procured and installed in our homes, hospitals and business premises, there is a justifiable need for a faster and more reliable change over system in an event of power outage.
In view of these considerations, this project is aimed at designing and constructing a workable power failure alarm with a auto-generator starting device which switches on the generator when power fails.
1.2 SIGNIFICANCE OF THE PROJECT
A failure in the power supply to some people causes only a irritant, they may have to reset a clock, but to other people especially business, they can and do cause thousands of pounds of damage. This damage may be in the form of lost food in a fridge or freezer, amounting to hundreds of naira of lost stock, it may be chemicals, medicines, and electronics.
A power cut may have cut the heater off in the greenhouse, a fan off in a computer room, it may have caused a computer to fail, there are hundreds of reasons that you need to know if there is or has been a power failure. This device is designed to inform you when the power has failed.
1.3 LIMITATION OF THE PROJECT
The power failure alarm with generator auto starting device, this switch is limited at performing three automatic actions;
To automatically start a generator
To indicate when there is power supply
To blow alarm when there is power failure.
1.4 ADVANTAGES OF THE PROJECT
The power failure alarm unit can be operated in single or three phase system. And it has the following advantages;
It minimizes damages to lives/equipment since it has its own monitoring system and its switching requires no human contact with the switch, thus eliminating human error.
It reduces its change over timing to the minimum due to its fast response to power outage.
It maintains high quality of service through its fast and prompt response.
Moreover, the size and captivity of the unit will depend upon the load for which it will be used. The unit is also portable, easy, convenient and safe to install.
1.5 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
1.6 APPLICATION OF POWER FAILURE SIGNAL
Why someone would need a power failure signal is to notify them that the electricity is out, you may wonder. After all, isn’t it pretty obvious when there is a power outage — the lights go out, the TV doesn’t work, and all other appliances. In most instances, it is pretty obvious when there’s a power outage, unless:
You aren’t home when it occurs, or
You are asleep, or
Only one circuit is affected (inevitably it’s the refrigerator!)
For those kinds of power outages, or for blackouts that happen at your vacant vacation house, a power failure alarm is a sure-fire device to receive immediate notifications. And in the summer when there’s an increase in power outages caused by severe weather, a power failure alarm is a good investment to protect your home and family.
1.7 SCOPE OF THE PROJECT
This project is a power supply monitoring device that will trigger a buzzer when the mains supply cuts off. At the same time, the light emitting diode will be turned ON. This device is helpful to inform the loss 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 loss of power supply and actions need to be taken to rectify the situation by providing alternative power supply or relocating the installation.
