Abstract | This research embodies the design, construction and simulation of a feeder pillar (415VAC) with over-current, overload and earth-fault protection with the aid of a phase sequence relay, contactor, earth-leakage circuit breaker and three-phase overload relay. The analog voltmeters in the various bus-bars (red, yellow and blue phases) in a conventional feeder pillar is replaced with a digital panel voltmeter indicating the voltage across a phase (240V) or lineto-line (415VAC) flowing through the bus-bars. The major reason for this research study is to prevent the constant changing of fuses. It also provides sufficient protection in electric power distribution, and easy identification of faults when encountered. The feeder pillar not only distributes power through the channels but also protects the transformer against damage through the use of the earth-leakage circuit breakers as well as miniature circuit breakers. The panel of the feeder is well earthed against lightning surges that can bring about damage to the distributing system. |
