Electrical engineering projects for students are closely application-oriented projects and these EEE projects are very simple projects which are about power failure alarms. This project is used in most of the industries where electrical power plays a major role and power failure alarms are needed compulsorily.
Project Title: Power supply failure alarm
Usually the total electronic circuit for such kind of projects need a power supply from the main source and an additional power supply is needed for alarm circuit alone. But in this case, there is no need of an additional power supply circuit and instead an electrolytic capacitor is used in the alarm circuit. Whenever the power supply is cut, then the electrolytic capacitor acts as the main source for transistor thereby produces an alarm too thus activating the alarm circuit. The electrolytic capacitors are used to achieve high capacitance per volume and keeps electrolyte as one of its plates. Mostly aluminium and tantanium are the two types of electrolytic capacitors.

In the field of electrical engineering, most of the protection for an industrial system can be given using relays or circuit breakers but alarms are the most fascinating systems for detecting power failure. But giving connections for an electronic circuit is easier than giving connections for an electrical circuit. This type of an alarm circuit can be given for power supplies of 5-15V and variation of the potentiometer is more important to check whether the buzzer in the alarm circuit is working or not. During the power failure, resistor pulls the base of the transistor and saturates from low and turns the buzzer ON. A piezoelectric buzzer is recommended to use in an electronic circuit and the operation of this electronic circuit can be categorized into three stages namely,
- Power supply circuit stage
- Power failure sensor stage
- Alarm circuit stage
Moreover, EEE projects also includes electronic circuits needed for the students to do their final year projects and these electrical projects act as ideas for many macro projects in future.
All diploma and engineering students can download this content for carrying out their final year projects or mini projects. Hope this content may benefit the students and we also provide the necessary circuit diagrams, their operation and project report clearly in this content.
