1.0 INTRODUCTION As the quest for change over on public power supply and stand by generation increase. Engineering have researches deep into the different methods of achieving to both manual and automatic types. It may not be taken seriously in some places where power supply is up to 90 constant or where intermittent outage causes no great damage. However, place where they have business centers, industrial centers and even cold rooms n […]

The main aim of any electric power supply in the world is to provide uninterrupted power supply at all times to all its consumers. Although in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient hence instability and outage. Power instability or outage in general does not promote development in the public and private sector. The inventors do not feel secure to c […]
This product is another beautiful addition to the thriving DEC/ATSxxx automatic changeover series from Decrownies electronics. This model is equipped with the auto start function which automatically starts the generator when there is main power failure (if it is enabled). It allows the user to start the generator from wherever it is installed by pressing a button on the device if auto start is disabled. It also has a timer which the u […]
This project work is on the design and construction of automatic changeover for 1-phase power supply. It provides a means of switching from AC mains to generator in case of failure in the existing phase but when there is no power in any of the system when then switchover to generator. This device brings solution to overcome power fluctuation/phase interruption by selecting next most healthy available phase to feed the equipment without […]
