ABSTRACT Uninterruptible power supplies (UPS) are used to provide power when regular utility power is unavailable.  Although they are commonly used for providing power in remote locations or emergencies, this is not because they are the same as auxiliary power units, emergency power units or standby generators. Unlike the aforementioned power... Continue Reading

ABSTRACT  The importance of power supply to any economy cannot be overemphasized. It the pivot on which the economic, industrial and technological development of any nation is hinged upon. This study was carried out to assess the state of power supply and use in Gyel District of Jos- South Local Government Area of Plateau State. Four communities... Continue Reading

ABSTRACT The uninterrupted power supply (UPS) is design to help in the offices, workshops and house hold appliances, due to the unstable power supply being supplied by (NEPA) presently known as Power Holding Company of Nigeria (PHCN) usually supply to us. With the help of the UPS we don't need to depend much on PHCN it is stress free because it... Continue Reading
