Abstract

The Cameroon development corporation (CDC) which is the second largest employer in Cameroon after the state is a public establishment which acquires, develop, and operates extensive plantation of tropical crops namely banana, rubber, and oil palm in the Littoral and southwest region of Cameroon.

These crops are processed top certain levels. In such a corporation, electrical power is highly used in running the equipment in the corporation and for general electrification within the cooperation.

CDC-TSD faces some challenges such as power failure from ENEO since the main electrical supply comes from the national grid managed by ENEO. Another challenge is that CDC faces a problem of imbalance voltages across its low voltage 3phase lines, that is a situation in which the voltage in one of the lines goes low as compared to the others. When such happens, the technicians change the phase manually.

This report presents the design of an Automatic Changeover system which will eliminate the challenges faced in this unit without human intervention. Thus, reducing the risk involved in manual changeover system.
