This project work deals on the design and construction of an automatic power changeover that will change/transfer control from MAINS to Gen set and can switch ON/OFF the Gen automatically. The system integrates phase selector in MAINS and changeover to Gen. It is designed in several blocks all combined to from one functional unit. A +5v regulated DC power supply unit forms the first block whose output is fed to priority encoder and decoder block. The output of the BCD – Decimal decoder is used to select the phase in priority through a transistor driver stage and electromagnetic relay that activates contactors. The least prioritized phase is the Gen set which contains a circuitry that automatically starts and stops the Gen set. The system is realized with TTL chips market. LEDs and AC panel lamps are used to indicate the status of the system while a manual switch is used to demonstrate the mode of operation of the system.

contributed immensely to the high rate of the world’s technological
growth. Power control and automation is a part of this field which is
applied in virtually anywhere electrical power is used, generated or
transmitted. Manual power change-over switches have been in existence
and in different forms and shapes. 1959, the advent of microelectronics
has paved way to modify the manually operated change-over switches. Thi ... Continue reading---
