Power problems such as power surge, high voltage spikes and power outages have caused a lot of damages in homes, offices etc. The problem of observing correctly power supply activities in electrical systems prompted the development of this device. This paper therefore presents the ‘Design of a ‘Power Failure Monitoring Data-Logger System’ that will monitor, record, alert and display all power failure activities on the Liquid Crystal display (LCD) unit. This data Logger (or data Recorder) is a microcontroller-based device that records dates and times of data acquisition in order to produce a sequence of events. In essence, the data is normally collected in non-volatile memory for later download to a computer system. This makes it ideally suited for applications requiring portability. The design is divided into the Power Supply, Data Logger, User Interface, LCD and the Microcontroller Units. The power supply activities in any electrical system are processed by the Microcontroller and stored in the Logger (Recorder). The Analysis is then displayed the LCD. The Microcontroller which is the major component is programmed in Micro-C language. It is however recommended that this Data Logger be improved upon to have access to wireless communication systems for automatic alarming, reporting and remote control of events as they are monitored. An automatic transfer Switch should be incorporated to change to any available back-up power source. In conclusion, proper use of Power failure monitor data Logger will greatly reduce the stress of personnel in monitoring power failure activities.
