Title

Smart Automatic Electricity Changeover Switches

Abstract

Electricity (energy), which plays a major role in economic development of a nation, forms the basis of this study, with interests in human, infrastructural and economic development. In most developing and underdeveloped parts of the world, the supply of electricity for industrial, commercial and domestic use is highly unstable(Ezema et al., 2019). This gives rise to the frequent use of alternative sources of power supply to meet up with the energy demands. The introduction of these alternative sources of supply brings forth the challenge of switching smoothly and timely between the mains supply and the alternative sources whenever there is a failure on the mains source. The first objective of this study was to design and implement a changeover switch that uses a revers bi-directional relay to decide when to change the power supplier i.e. from a utility power supplier to a secondary/ localized power supplier. The second objective was to design and implement a notification module which monitors the state of the switch and send a notification if it detects an anomaly. The third and last objective was to assess the effectiveness of the use of a connected and intelligent/smart changeover switch in deciding whether to change from a primary source to a secondary source or vice versa. The researcher developed a changeover switch model that Arduino microcontrollers to detect power in a line and automatically switch to auxiliary power if power is cut which satisfies the second research objective.The model is also capable of communicating to the user of the person in charge automatically. The researcher performed all the necessary black, white box tests and performance tests using the confusion matrix, the author found that the system had satisfactory performance. The system was tested in average response time, accuracy and it achieved 1.05 seconds and 95% respectively. Therefore, providing an improvement over the results obtained by other researchers such as (Ezema et al., 2019) and (Boma & Ikwuagwu, 2021) The gained results are signiﬁcant and conﬁrm the efﬁciency of the use of connected and intelligent/smart changeover switch in deciding whether to change from a primary source to a secondary source or vice versa .
