ABSTRACT

This project presents the construction of automatic change over switch in between the 3-phase electrical power supply. The purpose of this is to isolate human means of changing electrical power supply from one phase to another which not only dangerous for unprofessional or untrained personnel. Changing from one phase to another involves removing the cut-out fuse from one phase and inserts it into another available phase which not only takes time but could also leads to electrocution of the personnel doing such if his/her hand mistakenly touches live wire.

Every home in Nigeria or outside is connected to the 3-phase power supply but could only make use of one phase at a time which therefore requires switching over to other phase if the previous is interrupted.

Therefore, this project will solve the manual change over switch being operated by human being into automated change over switch which will reduce the stress being encountered and minimized the danger of electrocution involves.

The device is built around transformer, relay switch, contactor and NE 555 timer IC.

Keywords: transformer, 3-phase, electrocution, contactor.
