AUTOMATIC TRANSFER SWITCH WITH THREE PHASE SELECTOR [ ]


Constant supply of power is the wheel of growth to any nation’s economy. A country like Nigeria, where total power generation is less than one quarter of total demand, means of augmentation and smooth operation cannot be over emphasized. This paper presents a real laboratory design and construction of Automatic Transfer Switch (ATS) with three phase selector. The design method involves the use of electromechanical type relays, and comparators, etc. The ATS designed demonstrates its ability to perform automatic power change over activities easily without any human interaction.
